-# csv
+# Comma-Separated Values by RFC 4180
+A lightweight database in pure PHP<br>
+It will perfectly replace complex databases in simple projects
 
+## Requirements
+- PHP 8.4
+
+## Installation
+1. `composer require mirzaev/csv`
+2. Create a class that inherits `mirzaev/csv/database` and redefine the `database::FILE` constant
+3. Enjoy!
+
+## Example
+```php
+<?php
+
+// Library for CSV
+use mirzaev\csv\{database, record};
+
+// Initializing the database
+$database = new database('name', 'age', 'created');
+
+// Initializing the record
+$record = new record(['Arsen', '23', time());
+
+// Writing to the database
+$database->write($record);
+?>
+```
