 Nothing special is required for Apache to work. We've include the `.htaccess` file in the `public` folder. If rewriting is not working for you, please check that the `mod_rewrite` module (htaccess support) is enabled in the Apache configuration.
 
+#### .htaccess example
+
+Below is an example of an working `.htaccess` file used by simple-php-router.
+
+Simply create a new `.htaccess` file in your projects `public` directory and paste the contents below in your newly created file. This will redirect all requests to your `index.php` file (see Configuration section below).
+
+```
+RewriteEngine on
+RewriteCond %{SCRIPT_FILENAME} !-f
+RewriteCond %{SCRIPT_FILENAME} !-d
+RewriteCond %{SCRIPT_FILENAME} !-l
+RewriteRule ^(.*)$ index.php/$1
+```
+
 ### Configuration
 
 Create a new file, name it `routes.php` and place it in your library folder. This will be the file where you define all the routes for your project.
