 ## Code Style & Conventions
 - **PHP Standards**: Follow PSR-12. Use 4 spaces for indentation.
 - **Naming**: Classes `PascalCase` (e.g., `CodePressCMS`), methods `camelCase` (e.g., `renderMenu`), variables `camelCase`, config keys `snake_case`.
 - **Architecture**: 
-  - Core logic resides in `index.php`.
-  - Configuration in `config.php`.
-  - Public entry point is `public/index.php`.
- **Content**: Stored in `public/content/`. Supports `.md` (Markdown), `.php` (Dynamic), `.html` (Static).
- **Templating**: Simple string replacement `{{placeholder}}` in `templates/layout.html`.
+  - Core CMS logic in `engine/core/class/CodePressCMS.php`
+  - Bootstrap/requires in `engine/core/index.php`
+  - Configuration loaded from `config.json` via `engine/core/config.php`
+  - Public website entry point: `public/index.php`
+  - Admin entry point + routing: `public/admin.php`
+  - Admin authenticatie: `admin-console/src/AdminAuth.php`
+- **Content**: Stored in `content/`. Supports `.md` (Markdown), `.php` (Dynamic), `.html` (Static).
+- **Templating**: Mustache-style `{{placeholder}}` in `templates/layout.mustache` via `SimpleTemplate.php`.
 - **Navigation**: Auto-generated from directory structure. Folders require an index file to be clickable in breadcrumbs.
- **Security**: Always use `htmlspecialchars()` for outputting user/content data.
- **Git**: `main` is the clean CMS core. `e.noorlander` contains personal content. Do not mix them.
+- **Security**: 
+  - Always use `htmlspecialchars()` for outputting user/content data
+  - Use `realpath()` + prefix-check for path traversal prevention
+  - Admin forms require CSRF tokens via `AdminAuth::verifyCsrf()`
+  - Passwords stored as bcrypt hashes in `admin.json`
+- **Git**: `main` is the clean CMS core. `development` is de actieve development branch. `e.noorlander` bevat persoonlijke content. Niet mixen.
+
+## Admin Console
+- **File-based**: Geen database. Gebruikers opgeslagen in `admin-console/config/admin.json`
+- **Routing**: Via `?route=` parameter in `public/admin.php`
+- **Routes**: `login`, `logout`, `dashboard`, `content`, `content-edit`, `content-new`, `content-delete`, `config`, `plugins`, `users`
+- **Auth**: Session-based. `AdminAuth` class handelt login, logout, CSRF, brute-force lockout af
+- **Templates**: Pure PHP templates in `admin-console/templates/pages/`. Layout in `layout.php`

 ## Important: Title vs File/Directory Name Logic
 - **CRITICAL**: When user asks for "title" corrections, they usually mean **FILE/DIRECTORY NAME WITHOUT LANGUAGE PREFIX AND EXTENSIONS**, not the HTML title from content!
@@ -26,4 +101,10 @@
  - `en.php-testen` → display as "Php Testen" (not "ICT")
 - **Method**: Use `formatDisplayName()` to process file/directory names correctly
 - **Priority**: Directory names take precedence over file names when both exist
- **Language prefixes**: Always remove `nl.` or `en.` prefixes from display names
+- **Language prefixes**: Dynamisch verwijderd op basis van beschikbare talen via `getAvailableLanguages()`
+
+## Bekende aandachtspunten
+- LSP errors over "Undefined function" in PHP files zijn vals-positief (standaard PHP functies worden niet herkend door de LSP). Negeer deze.
+- Zie `TODO.md` voor alle openstaande verbeteringen en nieuwe features.
+- `vendor/` map bevat Composer dependencies (CommonMark, Mustache). Niet handmatig wijzigen.
+- `admin-console/config/admin.json` bevat wachtwoord-hashes. Niet committen met echte productie-wachtwoorden.

+# CodePress CMS - Verbeteringen TODO
+
+## Kritiek
+
+- [x] **Path traversal fix** - `str_replace('../')` in `getPage()` is te omzeilen. Gebruik `realpath()` met prefix-check (`CodePressCMS.php:313`)
+- [x] **JWT secret fallback** - Standaard `'your-secret-key-change-in-production'` maakt tokens forgeable (`admin-console/config/app.php:11`)
+- [x] **executePhpFile() onveilig** - Open `include` wrapper zonder pad-restrictie (`CMSAPI.php:164`)
+- [ ] **Plugin auto-loading** - Elke map in `plugins/` wordt blind geladen zonder allowlist of validatie (`PluginManager.php:40`)
+
+## Hoog
+
+- [x] **IP spoofing** - `X-Forwarded-For` header wordt blind vertrouwd in MQTTTracker (`MQTTTracker.php:211`)
+- [x] **Debug hardcoded** - `'debug' => true` hardcoded in admin config (`admin-console/config/app.php:6`)
+- [x] **Cookie security** - Cookies zonder `Secure`/`HttpOnly`/`SameSite` flags (`MQTTTracker.php:70`)
+- [ ] **autoLinkPageTitles()** - Regex kan geneste `<a>` tags produceren (`CodePressCMS.php:587`)
+- [ ] **MQTT wachtwoord** - Credentials in plain text JSON (`MQTTTracker.php:37`)
+
+## Medium
+
+- [x] **Dead code** - Dubbele `is_dir()` check, tweede blok onbereikbaar (`CodePressCMS.php:328-333`)
+- [x] **htmlspecialchars() op bestandspad** - Corrumpeert bestandslookups in `getPage()` en `getContentType()` (`CodePressCMS.php:311, 1294`)
+- [x] **Ongebruikte methode** - `scanForPageNames()` wordt nergens aangeroepen (`CodePressCMS.php:658-679`)
+- [x] **Orphaned docblock** - Dubbel docblock zonder bijbehorende methode (`CodePressCMS.php:607-611`)
+- [x] **Extra `</div>`** - Sluit een tag die nooit geopend is in `getDirectoryListing()` (`CodePressCMS.php:996`)
+- [x] **Dubbele require_once** - PluginManager/CMSAPI geladen in zowel index.php als constructor (`CodePressCMS.php:49-50`)
+- [x] **require_once autoload** - Autoloader opnieuw geladen in `parseMarkdown()` (`CodePressCMS.php:513`)
+- [x] **Breadcrumb titels ongeescaped** - `$title` direct in HTML zonder `htmlspecialchars()` (`CodePressCMS.php:1197`)
+- [x] **Zoekresultaat-URLs missen `&lang=`** - Taalparameter ontbreekt (`CodePressCMS.php:264`)
+- [x] **Operator precedence bug** - `!$x ?? true` evalueert als `(!$x) ?? true` (`MQTTTracker.php:131`)
+- [ ] **Taalwisselaar verliest pagina** - Wisselen van taal navigeert altijd naar homepage (`header.mustache:22`)
+- [ ] **ctime is geen creatietijd op Linux** - `stat()` ctime is inode-wijzigingstijd (`CodePressCMS.php:400`)
+- [ ] **getGuidePage() dupliceert markdown parsing** - Zelfde CommonMark setup als `parseMarkdown()` (`CodePressCMS.php:854`)
+- [ ] **HTMLBlock ontbrekende `</div>`** - Niet-gesloten tags bij null-check (`HTMLBlock.php:68`)
+- [ ] **formatDisplayName() redundante logica** - Dubbele checks en overtollige str_replace (`CodePressCMS.php:688`)
+
+## Laag
+
+- [x] **Hardcoded 'Ga naar'** - Niet vertaalbaar in `autoLinkPageTitles()` (`CodePressCMS.php:587`)
+- [x] **HTML lang attribuut** - `<html lang="en">` hardcoded i.p.v. dynamisch (`layout.mustache:2`)
+- [x] **console.log in productie** - Debug log in app.js (`app.js:54`)
+- [x] **Event listener leak** - N globale click listeners in forEach loop (`app.js:85`)
+- [x] **Sidebar toggle aria** - Ontbrekende `aria-label` en `aria-expanded` (`CodePressCMS.php:1171`)
+- [x] **Taalprefix hardcoded** - Alleen `nl|en` i.p.v. dynamisch uit config (`CodePressCMS.php:691, 190`)
+- [ ] **Geen type hints** - Ontbrekende type declarations op properties en methoden
+- [ ] **Public properties** - `$config`, `$currentLanguage`, `$searchResults` zouden private moeten zijn
+- [ ] **Inline CSS** - ~250 regels statische CSS in template i.p.v. extern bestand
+- [ ] **style.css is Bootstrap** - Bestandsnaam is misleidend, Bootstrap wordt mogelijk dubbel geladen
+- [ ] **Geen error handling op file_get_contents()** - Meerdere calls zonder return-check
+- [ ] **Logger slikt fouten** - `@file_put_contents()` met error suppression
+- [ ] **Logger tail() leest heel bestand** - Geheugenprobleem bij grote logbestanden
+- [ ] **Externe links missen rel="noreferrer"**
+- [ ] **Zoekformulier mist aria-label**
+- [ ] **mobile.css override Bootstrap utilities** met `!important`
+
+---
+
+## Admin Console - Nieuwe features
+
+### Hoog
+
+- [ ] **Markdown editor** - WYSIWYG/split-view Markdown editor integreren in content-edit (bijv. EasyMDE, SimpleMDE, of Toast UI Editor). Live preview, toolbar met opmaakknoppen, drag & drop afbeeldingen
+- [ ] **Plugin activeren/deactiveren** - Toggle knop per plugin in admin Plugins pagina. Schrijft `enabled: true/false` naar plugin `config.json`. PluginManager moet `enabled` status respecteren bij het laden
+- [ ] **Plugin API** - Uitgebreide API voor plugins zodat ze kunnen inhaken op CMS events (hooks/filters). Denk aan: `onPageLoad`, `onBeforeRender`, `onAfterRender`, `onSearch`, `onMenuBuild`. Plugins moeten sidebar content, head tags, en footer scripts kunnen injecteren
+
+### Medium
+
+- [ ] **Plugin configuratie editor** - Per-plugin config.json bewerken vanuit admin panel
+- [ ] **Bestand uploaden** - Afbeeldingen en bestanden uploaden via admin Content pagina
+- [ ] **Map aanmaken/verwijderen** - Directory management in admin Content pagina
+- [ ] **Admin activity log** - Logboek van alle admin acties (wie deed wat wanneer) met viewer in dashboard
+- [ ] **Wachtwoord wijzigen eigen account** - Apart formulier voor ingelogde gebruiker om eigen wachtwoord te wijzigen (met huidig wachtwoord verificatie)
+- [ ] **Admin thema** - Admin sidebar kleur overnemen van site thema config (`header_color`)
+
+### Laag
+
+- [ ] **Content preview** - Live preview van Markdown/HTML content naast de editor
+- [ ] **Content versioning** - Simpele file-based backup bij elke save (bijv. `.bak` bestanden)
+- [ ] **Zoeken in admin** - Zoekfunctie binnen de admin content browser
+- [ ] **Drag & drop** - Bestanden herordenen/verplaatsen via drag & drop
+- [ ] **Keyboard shortcuts** - Ctrl+S om op te slaan in editor, Ctrl+N voor nieuw bestand
+- [ ] **Dark mode** - Admin panel dark mode toggle
+- [ ] **Responsive admin** - Admin sidebar inklapbaar op mobiel (nu is het gestacked)

+# PHP Enum implementation inspired from SplEnum
+
+[![GitHub Actions][GA Image]][GA Link]
+[![Latest Stable Version](https://poser.pugx.org/myclabs/php-enum/version.png)](https://packagist.org/packages/myclabs/php-enum)
+[![Total Downloads](https://poser.pugx.org/myclabs/php-enum/downloads.png)](https://packagist.org/packages/myclabs/php-enum)
+[![Psalm Shepherd][Shepherd Image]][Shepherd Link]
+
+Maintenance for this project is [supported via Tidelift](https://tidelift.com/subscription/pkg/packagist-myclabs-php-enum?utm_source=packagist-myclabs-php-enum&utm_medium=referral&utm_campaign=readme).
+
+## Why?
+
+First, and mainly, `SplEnum` is not integrated to PHP, you have to install the extension separately.
+
+Using an enum instead of class constants provides the following advantages:
+
+- You can use an enum as a parameter type: `function setAction(Action $action) {`
+- You can use an enum as a return type: `function getAction() : Action {`
+- You can enrich the enum with methods (e.g. `format`, `parse`, …)
+- You can extend the enum to add new values (make your enum `final` to prevent it)
+- You can get a list of all the possible values (see below)
+
+This Enum class is not intended to replace class constants, but only to be used when it makes sense.
+
+## Installation
+
+```
+composer require myclabs/php-enum
+```
+
+## Declaration
+
+```php
+use MyCLabs\Enum\Enum;
+
+/**
+ * Action enum
+ *
+ * @extends Enum<Action::*>
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+
+## Usage
+
+```php
+$action = Action::VIEW();
+
+// or with a dynamic key:
+$action = Action::$key();
+// or with a dynamic value:
+$action = Action::from($value);
+// or
+$action = new Action($value);
+```
+
+As you can see, static methods are automatically implemented to provide quick access to an enum value.
+
+One advantage over using class constants is to be able to use an enum as a parameter type:
+
+```php
+function setAction(Action $action) {
+    // ...
+}
+```
+
+## Documentation
+
+- `__construct()` The constructor checks that the value exist in the enum
+- `__toString()` You can `echo $myValue`, it will display the enum value (value of the constant)
+- `getValue()` Returns the current value of the enum
+- `getKey()` Returns the key of the current value on Enum
+- `equals()` Tests whether enum instances are equal (returns `true` if enum values are equal, `false` otherwise)
+
+Static methods:
+
+- `from()` Creates an Enum instance, checking that the value exist in the enum
+- `toArray()` method Returns all possible values as an array (constant name in key, constant value in value)
+- `keys()` Returns the names (keys) of all constants in the Enum class
+- `values()` Returns instances of the Enum class of all Enum constants (constant name in key, Enum instance in value)
+- `isValid()` Check if tested value is valid on enum set
+- `isValidKey()` Check if tested key is valid on enum set
+- `assertValidValue()` Assert the value is valid on enum set, throwing exception otherwise
+- `search()` Return key for searched value
+
+### Static methods
+
+```php
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+
+// Static method:
+$action = Action::VIEW();
+$action = Action::EDIT();
+```
+
+Static method helpers are implemented using [`__callStatic()`](http://www.php.net/manual/en/language.oop5.overloading.php#object.callstatic).
+
+If you care about IDE autocompletion, you can either implement the static methods yourself:
+
+```php
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+
+    /**
+     * @return Action
+     */
+    public static function VIEW() {
+        return new Action(self::VIEW);
+    }
+}
+```
+
+or you can use phpdoc (this is supported in PhpStorm for example):
+
+```php
+/**
+ * @method static Action VIEW()
+ * @method static Action EDIT()
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+
+## Native enums and migration
+Native enum arrived to PHP in version 8.1: https://www.php.net/enumerations  
+If your project is running PHP 8.1+ or your library has it as a minimum requirement you should use it instead of this library.
+
+When migrating from `myclabs/php-enum`, the effort should be small if the usage was in the recommended way:
+- private constants
+- final classes
+- no method overridden
+
+Changes for migration:
+- Class definition should be changed from
+```php
+/**
+ * @method static Action VIEW()
+ * @method static Action EDIT()
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+ to
+```php
+enum Action: string
+{
+    case VIEW = 'view';
+    case EDIT = 'edit';
+}
+```
+All places where the class was used as a type will continue to work.
+
+Usages and the change needed:

+# Changelog
+
+## Version `v1.0.0`
+
+Significant improvements to the architecture, API and design of the library have been part of `v1.0.0`.
+Upgrading should be rather simple for most users though, since the public API has not changed a lot
+and only in places which are not used too frequently.
+
+A lot of effort has been put into this summary to document as many changes as possible.
+It is impossible to give a guarantee about the completeness of this list though.
+You should cover your uses of the library with tests yourself as well.
+
+The following summary compares `v0.3.0` to `v1.0.0`.
+
+### Breaking Changes
+
+- The library does now require PHP 7.4 and supports PHP 8.0. This move was made with the clear intention to drop support for PHP 7.4 at some point.
+- The primary interface and class of the library have been renamed to StudlyCaps to follow PSR-2:
+  - `\PhpMqtt\Client\Contracts\MQTTClient` &rarr; `\PhpMqtt\Client\Contracts\MqttClient`
+  - `\PhpMqtt\Client\MQTTClient` &rarr; `\PhpMqtt\Client\MqttClient`
+  - `\PhpMqtt\Client\Exceptions\MQTTClientException` &rarr; `\PhpMqtt\Client\Exceptions\MqttClientException`
+- Protocol specific logic has been extracted from the `MQTTClient` class to a new interface `\PhpMqtt\Client\Contracts\MessageProcessor` and the respective implementation for MQTT 3.1, `\PhpMqtt\Client\MessageProcessors\Mqtt31MessageProcessor`.
+  - The `MessageProcessor` is responsible for parsing and building packages on a byte level.
+  - Splitting the logic from the main class did not only reduce the overall complexity of the class, it also made testing a lot easier and builds a solid foundation for future development and extension by implementing more protocol versions (like MQTT 5).
+- Some `protected` properties have been changed to `private` to ensure they are not manipulated outside the offered scope, which is enforced through getters and setters. This change only affects users which actively inherited their own implementation from the library.
+- The QoS 2 message flow is now implemented properly and should just work.
+  
+#### Connection Settings
+
+- The `$caFile` parameter of the `MQTTClient` constructor as well as the `$username` and `$password` parameters of the `MQTTClient::connect()` method have been moved to the `ConnectionSettings` class.
+- The `ConnectionSettings` use fluent setters for configuration now ([see README](README.md)). 
+- The `ConnectionSettings`` passed to `MQTTClient::connect()` are now validated and may not contain invalid configuration. In case of invalid configuration, a `\PhpMqtt\Client\Exceptions\ConfigurationInvalidException` is thrown.
+- Additional TLS options have been added to the `ConnectionSettings` to support more uses cases with secured connections.
+
+#### Methods
+
+- Most methods can now throw a `\PhpMqtt\Client\Exceptions\RepositoryException` if an interaction with the repository fails. This should happen with the `MemoryRepository` only in exceptional situations, but when implementing persisted repositories, this may happen more frequently and should therefore be considered.
+- The `MQTTClient::connect()` method had a parameter called `$sendCleanSessionFlag` while the `MqttClient::connect()` method has the same parameter, but called `$useCleanSession`. The parameters `$username` and `$password` have been removed entirely and are now part of the `ConnectionSettings`.
+- The method `MQTTClient::close()` has been renamed to `MqttClient::disconnect()`.
+- The parameter `$topic` of `MQTTClient::subscribe()` has been renamed to `$topicFilter` to reflect its meaning (which is a topic, but with wildcards). The `$callback` parameter can be `null` now and has `null` as default.
+- The parameter `$topic` of `MQTTClient::unsubscribe()` has been renamed to `$topicFilter` as well.
+
+#### Exceptions
+
+- New exceptions have been introduced and old ones were removed. All exceptions inherit from `\PhpMqtt\Client\Exceptions\MqttClientException` as base. You should ensure your calls to methods of the `MqttClient` handle the exceptions appropriately.
+- The exception constants previously defined on the `\PhpMqtt\Client\MQTTClient` class have been moved to the respective exception classes. This change only affects you if you used these constants to render detailed exception information for your users.
+
+#### Repositories
+
+- The `\PhpMqtt\Client\Contracts\Repository` interface has been changed significantly and summarizing all changes would be quite hard anyway. We therefore encourage you to have a look at the interface again and update your own implementation(s) of it, if you have any.
+
+#### Logger
+
+- The `\PhpMqtt\Client\Logger` implementation of `Psr\Log\LoggerInterface` does now decorate the log output with details about the MQTT client (format: `MQTT [{host}:{port}] [{clientId}] {message}`).
+
+### Additions
+
+- It is now possible to register event handlers for received messages. In combination with subscriptions without a callback, this allows to use centralized logic for multiple subscriptions. It also can be used for centralized logging, for example.
+- A lot of unit and integration tests have been added which cover most parts of the library, especially the non-exception paths.
+- All unit tests, integration tests, and the code style are enforced using a GitHub Actions workflow which runs under Ubuntu against multiple MQTT brokers (currently Mosquitto, HiveMQ and EMQ X). Contributing became easier therefore, but we expect that tests are added for changes and additions.
+  - To run the tests locally, an MQTT broker without authorization needs to run at `localhost:1883` (or the configuration in `phpunit.xml` is changed instead).
+- The project is now analyzed using [sonarcloud.io](https://sonarcloud.io/dashboard?id=php-mqtt_client) which helps us keep up the high standards of the library.
+
+#### Methods

+
+[`php-mqtt/client`](https://packagist.org/packages/php-mqtt/client) was created by, and is maintained
+by [Marvin Mall](https://github.com/namoshek).
+It allows you to connect to an MQTT broker where you can publish messages and subscribe to topics.
+The current implementation supports all QoS levels ([with limitations](#limitations)).
+
+## Installation
+
+The package is available on [packagist.org](https://packagist.org/packages/php-mqtt/client) and can be installed using `composer`:
+
+```bash
+composer require php-mqtt/client
+```
+
+The package requires PHP version 8.0 or higher.
+
+## Usage
+
+In the following, only a few very basic examples are given. For more elaborate examples, have a look at the
+[`php-mqtt/client-examples` repository](https://github.com/php-mqtt/client-examples).
+
+### Publish
+
+A very basic publish example using QoS 0 requires only three steps: connect, publish and disconnect
+
+```php
+$server   = 'some-broker.example.com';
+$port     = 1883;
+$clientId = 'test-publisher';
+
+$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
+$mqtt->connect();
+$mqtt->publish('php-mqtt/client/test', 'Hello World!', 0);
+$mqtt->disconnect();
+```
+
+If you do not want to pass a `$clientId`, a random one will be generated for you. This will basically force a clean session implicitly.
+
+Be also aware that most of the methods can throw exceptions. The above example does not add any exception handling for brevity.
+
+### Subscribe
+
+Subscribing is a little more complex than publishing as it requires to run an event loop which reads, parses and handles messages from the broker:
+
+```php
+$server   = 'some-broker.example.com';
+$port     = 1883;
+$clientId = 'test-subscriber';
+
+$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
+$mqtt->connect();
+$mqtt->subscribe('php-mqtt/client/test', function ($topic, $message, $retained, $matchedWildcards) {
+    echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
+}, 0);
+$mqtt->loop(true);
+$mqtt->disconnect();
+```
+
+While the loop is active, you can use `$mqtt->interrupt()` to send an interrupt signal to the loop.
+This will terminate the loop before it starts its next iteration. You can call this method using `pcntl_signal(SIGINT, $handler)` for example:
+
+```php
+pcntl_async_signals(true);
+
+$clientId = 'test-subscriber';
+
+$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
+pcntl_signal(SIGINT, function (int $signal, $info) use ($mqtt) {
+    $mqtt->interrupt();
+});
+$mqtt->connect();
+$mqtt->subscribe('php-mqtt/client/test', function ($topic, $message, $retained, $matchedWildcards) {
+    echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
+}, 0);
+$mqtt->loop(true);
+$mqtt->disconnect();
+```
+
+### Client Settings
+
+As shown in the examples above, the `MqttClient` takes the server, port and client id as first, second and third parameter.
+As fourth parameter, the protocol level can be passed. Currently supported is MQTT v3.1,
+available as constant `MqttClient::MQTT_3_1`.
+A fifth parameter allows passing a repository (currently, only a `MemoryRepository` is available by default).
+Lastly, a logger can be passed as sixth parameter. If none is given, a null logger is used instead.
+
+Example:
+```php
+$mqtt = new \PhpMqtt\Client\MqttClient(
+    $server, 
+    $port, 
+    $clientId,
+    \PhpMqtt\Client\MqttClient::MQTT_3_1,
+    new \PhpMqtt\Client\Repositories\MemoryRepository(),
+    new Logger()
+);
+```
+
+The `Logger` must implement the `Psr\Log\LoggerInterface`.
+
+### Connection Settings
+
+The `connect()` method of the `MqttClient` takes two optional parameters:
+1. A `ConnectionSettings` instance
+2. A `boolean` flag indicating whether a clean session should be requested (a random client id does this implicitly)
+
+Example:
+```php
+$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
+
+$connectionSettings = (new \PhpMqtt\Client\ConnectionSettings)
+    ->setConnectTimeout(3)
+    ->setUseTls(true)
+    ->setTlsSelfSignedAllowed(true);
+    
+$mqtt->connect($connectionSettings, true);
+```
+
+The `ConnectionSettings` class provides a few settings through a fluent interface. The type itself is immutable,
+and a new `ConnectionSettings` instance will be created for each added option.
+This also prevents changes to the connection settings after a connection has been established.
+
+The following is a complete list of options with their respective default:
+
+```php
+$connectionSettings = (new \PhpMqtt\Client\ConnectionSettings)
+
+    // The username used for authentication when connecting to the broker.
+    ->setUsername(null)
+    
+    // The password used for authentication when connecting to the broker.
+    ->setPassword(null)
+    
+    // Whether to use a blocking socket when publishing messages or not.
+    // Normally, this setting can be ignored. When publishing large messages with multiple kilobytes in size,
+    // a blocking socket may be required if the receipt buffer of the broker is not large enough.
+    //
+    // Note: This setting has no effect on subscriptions, only on the publishing of messages.
+    ->useBlockingSocket(false)
+    
+    // The connect timeout defines the maximum amount of seconds the client will try to establish
+    // a socket connection with the broker. The value cannot be less than 1 second.
+    ->setConnectTimeout(60)
+    
+    // The socket timeout is the maximum amount of idle time in seconds for the socket connection.
+    // If no data is read or sent for the given amount of seconds, the socket will be closed.
+    // The value cannot be less than 1 second.
+    ->setSocketTimeout(5)
+    
+    // The resend timeout is the number of seconds the client will wait before sending a duplicate
+    // of pending messages without acknowledgement. The value cannot be less than 1 second.
+    ->setResendTimeout(10)
+    
+    // This flag determines whether the client will try to reconnect automatically
+    // if it notices a disconnect while sending data.
+    // The setting cannot be used together with the clean session flag.
+    ->setReconnectAutomatically(false)
+    
+    // Defines the maximum number of reconnect attempts until the client gives up.
+    // This setting is only relevant if setReconnectAutomatically() is set to true.
+    ->setMaxReconnectAttempts(3)
+    
+    // Defines the delay between reconnect attempts in milliseconds.
+    // This setting is only relevant if setReconnectAutomatically() is set to true.
+    ->setDelayBetweenReconnectAttempts(0)
+    
+    // The keep alive interval is the number of seconds the client will wait without sending a message
+    // until it sends a keep alive signal (ping) to the broker. The value cannot be less than 1 second
+    // and may not be higher than 65535 seconds. A reasonable value is 10 seconds (the default).
+    ->setKeepAliveInterval(10)
+    
+    // If the broker should publish a last will message in the name of the client when the client
+    // disconnects abruptly, this setting defines the topic on which the message will be published.
+    //
+    // A last will message will only be published if both this setting as well as the last will
+    // message are configured.
+    ->setLastWillTopic(null)
+    
+    // If the broker should publish a last will message in the name of the client when the client
+    // disconnects abruptly, this setting defines the message which will be published.
+    //
+    // A last will message will only be published if both this setting as well as the last will
+    // topic are configured.
+    ->setLastWillMessage(null)
+    
+    // The quality of service level the last will message of the client will be published with,
+    // if it gets triggered.
+    ->setLastWillQualityOfService(0)
+    
+    // This flag determines if the last will message of the client will be retained, if it gets
+    // triggered. Using this setting can be handy to signal that a client is offline by publishing
+    // a retained offline state in the last will and an online state as first message on connect.
+    ->setRetainLastWill(false)
+    
+    // This flag determines if TLS should be used for the connection. The port which is used to
+    // connect to the broker must support TLS connections.
+    ->setUseTls(false)
+    
+    // This flag determines if the peer certificate is verified, if TLS is used.
+    ->setTlsVerifyPeer(true)
+    
+    // This flag determines if the peer name is verified, if TLS is used.
+    ->setTlsVerifyPeerName(true)
+    
+    // This flag determines if self signed certificates of the peer should be accepted.
+    // Setting this to TRUE implies a security risk and should be avoided for production
+    // scenarios and public services.
+    ->setTlsSelfSignedAllowed(false)
+    
+    // The path to a Certificate Authority certificate which is used to verify the peer
+    // certificate, if TLS is used.
+    ->setTlsCertificateAuthorityFile(null)
+    
+    // The path to a directory containing Certificate Authority certificates which are
+    // used to verify the peer certificate, if TLS is used.
+    ->setTlsCertificateAuthorityPath(null)
+    
+    // The path to a client certificate file used for authentication, if TLS is used.
+    //
+    // The client certificate must be PEM encoded. It may optionally contain the
+    // certificate chain of issuers.
+    ->setTlsClientCertificateFile(null)
+    
+    // The path to a client certificate key file used for authentication, if TLS is used.
+    //
+    // This option requires ConnectionSettings::setTlsClientCertificateFile() to be used as well.
+    ->setTlsClientCertificateKeyFile(null)
+    
+    // The passphrase used to decrypt the private key of the client certificate,
+    // which in return is used for authentication, if TLS is used.
+    //
+    // This option requires ConnectionSettings::setTlsClientCertificateFile() and
+    // ConnectionSettings::setTlsClientCertificateKeyFile() to be used as well.
+    ->setTlsClientCertificateKeyPassphrase(null);
+
+     // The TLS ALPN is used to establish a TLS encrypted mqtt connection on port 443,
+     // which usually is reserved for TLS encrypted HTTP traffic.
+     ->setTlsAlpn(null);
+```
+
+### Hooks
+
+The client includes a flexible and powerful hook system to allow custom behaviors during different stages of the MQTT lifecycle. Hooks are registered using closures and can be added or removed dynamically at runtime.
+
+> 💡 All hooks receive the MQTT client instance (`MqttClient`) as their first argument, allowing full access to the client's capabilities from within the hook.
+
+> 💡 Each hook is executed in a `try-catch` block to ensure no individual exception can crash the loop or hook processing.
+
+#### Loop Event Hooks
+
+Called on each iteration of the MQTT client's loop. This hook is especially useful to implement timeouts or other deadlock-prevention logic.
+
+##### Register
+
+```php
+$callback = function (MqttClient $mqtt, float $elapsedTime) {
+    echo "Running for {$elapsedTime} seconds already.";
+};
+
+$mqtt->registerLoopEventHandler($callback);
+```
+
+##### Unregister
+
+```php
+$mqtt->unregisterLoopEventHandler($callback); // Unregister specific event handler
+$mqtt->unregisterLoopEventHandler(); // Unregister all event handlers
+```
+
+#### Publish Event Hooks
+
+Triggered every time a message is published to the broker. This hook is useful to implement centralized logging or metrics.
+
+##### Register
+
+```php
+$callback = function (
+    MqttClient $mqtt,
+    string $topic,
+    string $message,
+    ?int $messageId,
+    int $qualityOfService,
+    bool $retain
+) {
+    echo "Published to [{$topic}]: {$message}";
+};
+
+$mqtt->registerPublishEventHandler($callback);
+```
+
+##### Unregister
+
+```php
+$mqtt->unregisterPublishEventHandler($callback); // Unregister specific event handler
+$mqtt->unregisterPublishEventHandler(); // Unregister all event handlers
+```
+
+#### Message Received Hooks
+
+Executed when a message is received from the broker as part of a subscription. This hook is useful to implement centralized logging or metrics.
+
+##### Register
+
+```php
+$callback = function (
+    MqttClient $mqtt,
+    string $topic,
+    string $message,
+    int $qualityOfService,
+    bool $retained
+) {
+    echo "Message on [{$topic}]: {$message}";
+};
+
+$mqtt->registerMessageReceivedEventHandler($callback);
+```
+
+##### Unregister
+
+```php
+$mqtt->unregisterMessageReceivedEventHandler($callback); // Unregister specific event handler
+$mqtt->unregisterMessageReceivedEventHandler(); // Unregister all event handlers
+```
+
+#### Connected Hooks
+
+Invoked when the client connects to the broker (initial or auto-reconnect).
+
+##### Register
+
+```php
+$callback = function (MqttClient $mqtt, bool $isAutoReconnect) {
+    echo $isAutoReconnect ? "Auto-reconnected!" : "Connected!";
+};
+
+$mqtt->registerConnectedEventHandler($callback);
+```
+
+##### Unregister
+
+```php
+$mqtt->unregisterConnectedEventHandler($callback); // Unregister specific event handler
+$mqtt->unregisterConnectedEventHandler(); // Unregister all event handlers
+```
+
+## Features
+
+- Supported MQTT Versions
+  - [x] v3 (just don't use v3.1 features like username & password)
+  - [x] v3.1
+  - [x] v3.1.1
+  - [ ] v5.0
+- Transport
+  - [x] TCP (unsecured)
+  - [x] TLS (secured, verifies the peer using a certificate authority file)
+- Connect
+  - [x] Last Will
+  - [x] Message Retention
+  - [x] Authentication (username & password)
+  - [x] TLS encrypted connections
+  - [ ] Clean Session (can be set and sent, but the client has no persistence for QoS 2 messages)
+- Publish
+  - [x] QoS Level 0
+  - [x] QoS Level 1 (limitation: no persisted state across sessions)
+  - [x] QoS Level 2 (limitation: no persisted state across sessions)
+- Subscribe
+  - [x] QoS Level 0
+  - [x] QoS Level 1
+  - [x] QoS Level 2 (limitation: no persisted state across sessions)
+- Supported Message Length: unlimited _(no limits enforced, although the MQTT protocol supports only up to 256MB which one shouldn't use even remotely anyway)_
+- Logging possible (`Psr\Log\LoggerInterface` can be passed to the client)
+- Persistence Drivers
+  - [x] In-Memory Driver
+  - [ ] Redis Driver
+  
+## Limitations
+  
+- Message flows with a QoS level higher than 0 are not persisted as the default implementation uses an in-memory repository for data.
+  To avoid issues with broken message flows, use the clean session flag to indicate that you don't care about old data.
+  It will not only instruct the broker to consider the connection new (without previous state), but will also reset the registered repository.
+  
+## Developing & Testing
+
+### Certificates (TLS)
+
+To run the tests (especially the TLS tests), you will need to create certificates. A command has been provided for this:
+```sh
+sh create-certificates.sh
+```
+This will create all required certificates in the `.ci/tls/` directory. The same script is used for continuous integration as well.
+
+### MQTT Broker for Testing
+
+Running the tests expects an MQTT broker to be running. The easiest way to run an MQTT broker is through Docker:
+```sh
+docker run --rm -it \
+  -p 1883:1883 \
+  -p 1884:1884 \
+  -p 8883:8883 \
+  -p 8884:8884 \
+  -v $(pwd)/.ci/tls:/mosquitto-certs \
+  -v $(pwd)/.ci/mosquitto.conf:/mosquitto/config/mosquitto.conf \
+  -v $(pwd)/.ci/mosquitto.passwd:/mosquitto/config/mosquitto.passwd \
+  eclipse-mosquitto:1.6
+```
+When run from the project directory, this will spawn a Mosquitto MQTT broker configured with the generated TLS certificates and a custom configuration.
+
+In case you intend to run a different broker or using a different method, or use a public broker instead,
+you will need to adjust the environment variables defined in `phpunit.xml` accordingly.
