+## Dependencies
+1. [PHP 8.4](https://www.php.net/releases/8.4/en.php)
+2. [Composer](https://getcomposer.org/) (php package manager)
+
+## Installation
+`composer require mirzaev/baza`
+
+## Example
+```php
+<?php
+
+use mirzaev\baza\database,
+    mirzaev\baza\column,
+    mirzaev\baza\record,
+    mirzaev\baza\enumerations\encoding,

+
+// Initializing the database
+$database = new database()

+        new column('age', type::integer),
+        new column('height', type::float)
+    )
+    ->connect(__DIR__ . DIRECTORY_SEPARATOR . 'database.ba');
+
+// Initializing the record
+$record = $database->record(
+    'Arsen',
+    'Mirzaev',
+    23,
+    (float) 165
+);
+
