+## Installation
+
+You can install this package using composer. To add it to your `composer.json`:
+
+    composer require iamcal/sql-parser
+
+You can then load it using the composer autoloader:
+
+    require_once 'vendor/autoload.php';
+    use iamcal\SQLParser;
+
+    $parser = new SQLParser();
+
+If you don't use composer, you can skip the autoloader and include `src/SQLParser.php` directly.
