+# RRZE\WP\Plugin
+
+This PHP library is designed to simplify the management of WordPress plugin files and directories. It provides methods for retrieving information about the plugin, such as its file path, basename, directory, URL, version, and slug.
+
+## Usage
+
+To use this class, simply instantiate it with the full path and filename of the plugin:
+```php
+$plugin = new RRZE\WP\Plugin(__FILE__);
+```
+
+Then call the loaded() method to initialize the plugin properties:
+```php
+$plugin->loaded();
+```
+
+You can now access various information about the plugin:
+```php
+$plugin_file = $plugin->getFile();
+$basename = $plugin->getBasename();
+$directory = $plugin->getDirectory();
+$url = $plugin->getUrl();
+$slug = $plugin->getSlug();
+$version = $plugin->getVersion();
+```
+
+## Methods
+
+- `getFile()`: Get the full path and filename of the plugin.
+- `getBasename()`: Get the basename of the plugin.
+- `getDirectory()`: Get the filesystem directory path for the plugin.
+- `getPath(string $path)`: Get the filesystem directory path for a specific file or directory within the plugin.
+- `getUrl(string $path)`: Get the URL directory path for a specific file or directory within the plugin.
+- `getSlug()`: Get the slug of the plugin.
+- `getVersion()`: Get the version of the plugin.

+# RRZE\WP\Settings
+
+The objective of this PHP library is to simplify the process of creating settings pages for WordPress plugins. Traditionally, developers have utilized the Settings API or custom code for this purpose. Although the Settings API functions well, it necessitates substantial setup effort. For instance, developers must manually write the HTML code for their options. Additionally, incorporating tabs and tab-sections can become rather complex. This PHP library aims to streamline these tasks and make settings page creation more straightforward.
+
+Based on the package `jeffreyvanrossum/wp-settings`.
+
+## Usage
+
+### Basic example
+
+```php
+use RRZE\WP\Settings\Settings;
+
+$settings = new Settings(__('My Plugin Settings'));
+
+$tab = $settings->addTab(__('Tab One', 'textdomain'));
+
+$section = $tab->addSection(__('Section One', 'textdomain'));
+
+$section->addOption('text', [
+    'name' => 'title',
+    'label' => __('Title', 'textdomain')
+]);
+
+$settings->build();
+```
+
+### Initializing the Settings class
+
+```php
+use RRZE\WP\Settings\Settings;
+
+$settings = new Settings(__('Custom Settings', 'textdomain'));
+```
+
+The constructor supports two parameters, namely `$title` and `$slug`. By default, the page slug is generated by sanitizing the title. If there's a specific slug preference, it can be passed as the second parameter to the constructor.
+
+Additional methods available in this class include:
+
+```php
+$settings->setCapability('manage_options')
+    ->setOptionName('my_plugin_option')
+    ->setMenuTitle(__('My Plugin', 'textdomain'))
+    ->setMenuIcon('dashicons-admin-generic')
+    ->setMenuPosition(5)
+    ->setMenuParentSlug('options-general.php');
+```
+
+### Tabs
+
+Tabs will be displayed only if there is more than one tab available.
+
+```php
+$settings->addTab(__('General', 'textdomain'));
+```
+
+### Sections
+
+The `addSection` method can be called from an instance of `Tab`. It can also be called from the `Settings` instance. Subsequently, it will be added to the last created `Tab`.
+
+```php
+$tab->addSection(__('Section One', 'textdomain'));
+```
+
+If sections are desired to be displayed as submenu-items, the following can be done:
+
+```php
+$tab->addSection('Section One', ['as_link' => true]);
+```
+
+Note that this only has an effect when there are more than one `as_link` sections.
+
+### Options
+
+To add an option, you either call the `addOption` method from an instance of `Section`. `addOption` can also be called from the `Settings` instance. The option will then be added to the last created section.
+
+#### Text
+
+```php
+$section->addOption('text', [
+    'name' => 'option_1',
+    'label' => __('Option 1', 'textdomain')
+]);
+```
+
+#### Textarea
+
+```php
+$section->addOption('textarea', [
+    'name' => 'option_1',
+    'label' => __('Option 1', 'textdomain')
+]);
+```
+
+#### Checkbox
+
+```php
+$section->addOption('checkbox', [
+    'name' => 'option_1',
+    'label' => __('Option 1', 'textdomain')
+]);
+```
+
+#### Checkbox Multiple
+
+```php
+$section->addOption('checkbox-multiple', [
+    'name' => 'multiple_options_1',
+    'label' => __('Multiple Options 1', 'textdomain'),
+    'options' => [
+        'option_1' => __('Option 1', 'rrze-autoshare'),
+        'option_2' => __('Option 2', 'rrze-autoshare')
+    ],
+]);
+```
+
+#### Radio Group
+
+```php
+$section->addOption('radio-group', [
+    'name' => 'radio_group_1',
+    'label' => __('Radio Group 1', 'textdomain'),
+    'options' => [
+        'option_1' => __('Option 1', 'rrze-autoshare'),
+        'option_2' => __('Option 2', 'rrze-autoshare')
+    ],
+]);
+```
+
+#### Select
+
+```php
+$section->addOption('select', [
+    'name' => 'option_1',
+    'label' => __( 'Option 1', 'textdomain' ),
+    'options' => [
+        'value_1' => 'Label 1',
+        'value_2' => 'Label 2'
+    ]
+]);
+```
+
+#### Select Multiple
+
+```php
+$section->addOption('select-multiple', [
+    'name' => 'option_1',
+    'label' => __('Option 1', 'textdomain'),
+    'options' => [
+        'value_1' => 'Label 1',
+        'value_2' => 'Label 2'
+    ]
+] );
+```
+
+#### Password
+
+```php
+$section->addOption('password', [
+    'name' => 'password_1',
+    'label' => __('Password 1', 'textdomain')
+]);
+```
+
+### Validate
+
+An option can be validated, allowing for the passing of a callback and a feedback message. Multiple validation rules can be passed as well.
+
+```php
+$section->addOption('text', [
+    'name' => 'custom_api_key',
+    'label' => __('API Key', 'textdomain'),
+    'validate' => [
+        [
+            'feedback' => __('The API key is too short.', 'textdomain'),
+            'callback' => fn($value) => strlen($value) > 35
+        ]
+    ]
+]);
+```
+
+### Sanitize
+
+A sanitize callback can be passed.
+
+```php
+$section->addOption('text', [
+    'name' => 'custom_api_key',
+    'label' => __('API Key', 'textdomain'),
+    'santitize' => fn($value) => sanitize_key($value)
+]);
+```
+
+### Additional attributes
+
+#### Description
+
+```php
+$section->addOption('text', [
+    'name' => 'custom_api_key',
+    'label' => __('API Key', 'textdomain'),
+    'description' => __('Enter the API key here.', 'textdomain')
+]);
+```
+
+#### Placeholder
+
+```php
+$section->addOption('text', [
+    'name' => 'custom_api_key',
+    'label' => __('API Key', 'textdomain'),
+    'placeholder' => __('Enter the API key here.', 'textdomain')
+]);
+```
+
+#### Default value
+
+```php
+$section->addOption('text', [
+    'name' => 'custom_api_key',
+    'label' => __('API Key', 'textdomain'),
+    'default' => 'default_value'
+]);
+```
+
+#### CSS classes
+
+```php
+$section->addOption('text', [
+    'name' => 'custom_api_key',
+    'label' => __('API Key', 'textdomain'),
+    'css' => [
+        'label_class' => 'regular-label',
+        'input_class' => 'regular-text'
+    ]
+]);
+```
+
+### Hooks
+
+```php
+add_filter('rrze_wp_settings_new_options', array $newOptions, array $currentOptions)
+```
+
+```php
+add_filter('rrze_wp_settings_new_option_{$optionName}', mixed $value, object \RRZE\WP\Settings\Options\Type)
+```
+
+```php
+add_filter('rrze_wp_settings_option_type_map', array $optionTypeMap)
+```
+
+```php
+add_filter('rrze_wp_settings_template_include', string $fileName, array $vars)
+```
+
+```php
+add_action('rrze_wp_settings_after_update_option', string $optionName, array $options)
+```
+
+### Adding a custom option type
+
+To add a custom option type, the `rrze_wp_settings_option_type_map` filter can be used.
+
+```php
+add_filter('rrze_wp_settings_option_type_map', function($options){
+    $options['custom'] = MyCustomOption::class;
+    return $options;
+});
+```
+
+Next, the class `MyCustomOption` must be added for the custom option type.
+
+```php
+use RRZE\WP\Settings\Options\Type;
+
+class MyCustomOption extends Type
+{
+    public $template = 'custom-option';
+
+    public function render()
+    {
+        echo 'My custom option HTML';
+    }
+}
+```
+
+Once registered, the option type can be used as follows:
+
+```php
+$settings->addOption('custom-option', [
+    'name' => 'my_option_name',
+    'label' => __('My label', 'textdomain')
+]);
+```
