**Slim Framework** is a lightweight PHP micro‑framework that helps you quickly build web applications and APIs. While some frameworks are available via Softaculous, Slim requires **manual installation** on your hosting account.

## Why Use Slim Framework?

- Minimalist design, ideal for RESTful APIs.
- Easy to learn and extend with middleware.
- Supports routing, dependency injection, and PSR standards.
- Lightweight and fast compared to larger frameworks.

## Steps to Install Slim Framework (Manual)

1. **Download Slim Framework.**

   - Visit the official GitHub repository: Slim Framework.
   - Download the latest `.zip` file.
2. **Extract Files.**

   - Unzip the downloaded package on your local computer.
   - You’ll see a folder named `Slim-x.y.z` (where `x.y.z` is the version number).
3. **Upload Files to Your Hosting Account.**

   - Use FTP or File Manager in cPanel to upload the contents of the extracted folder.
   - Place them in the `public_html` directory if you want Slim at the root (e.g., `example.com`).
   - Alternatively, upload to a subdirectory (e.g., `example.com/slim`).
4. **Create a Test Application.**

   - Inside `public_html`, create a file named `slimtest.php`.
   - Add the following sample code:

     ```
     <?php
     require 'Slim/Slim.php';
     \Slim\Slim::registerAutoloader();

     $app = new \Slim\Slim();

     $app->get('/hello/:name', function ($name) {
         echo "Hello, $name";
     });

     $app->run();
     ?>
     ```
5. **Run the Application.**

   - In your browser, go to:

     - `http://example.com/slimtest.php/hello/world`
   - You should see:

     ```
     Hello, world
     ```
6. **Adjust Paths if Needed.**

   - If you uploaded Slim to a subdirectory, update the `require` path in `slimtest.php` accordingly.

> **Note:**
- Slim Framework is compatible with all **ruachost.com** accounts.
- Always use strong admin and database passwords if connecting Slim to a database.
- Keep Slim updated to prevent vulnerabilities.
- Consider enabling automatic backups for added protection.
