+
+This guide covers all installation methods for the Kirby Loop plugin.
+
+## Prerequisites
+
+Before installing the plugin, ensure your system meets these requirements:
+
+- **Kirby CMS**: Version 4.0 or higher
+- **PHP**: Version 8.3 or higher
+- **SQLite**: Support enabled (usually included by default in PHP)
+
+## Installation Methods
+
+### Method 1: Composer (Recommended)
+
+Composer is the preferred installation method
+
+```bash
+composer require moinframe/kirby-loop
+```
+
+### Method 2: Manual Installation
+
+For environments where Composer isn't available or preferred:
+
+1. **Download the plugin**
+   - Visit the [GitHub releases page](https://github.com/moinframe/kirby-loop/releases)
+   - Download the latest version as a ZIP file
+
+2. **Extract and place**
+   - Unzip the downloaded archive
+   - Rename the folder to `loop` (remove version numbers)
+   - Move the folder to `/site/plugins/loop`
+
+3. **Verify installation**
+   - The plugin folder should contain `index.php` and other plugin files
+   - Your final structure should be: `/site/plugins/loop/index.php`
+
+### Method 3: Git Submodule
+
+For projects using Git version control, submodules provide a clean way to include the plugin:
+
+```bash
+git submodule add https://github.com/moinframe/kirby-loop.git site/plugins/loop
+```
+
+## Next Steps
+
+After successful installation:
