 # Database
 
-Flarum supports a variety of database systems, including MySQL, PostgreSQL, and SQLite. Most extensions will not have to worry about the specifics of the database system, as [Laravel's query builder](https://laravel.com/docs/11.x/queries) handles the differences between them. However, you can still run into instances where you need to write certain database operations differently depending on the database system. This section aims to document some of the common pitfalls and solutions.

 Flarum uses [Composer](https://getcomposer.org) to manage its dependencies and extensions. If you're not familiar with it, read [our guide](composer.md) for information on what it is and how to set it up. Afterwards, run this command in an empty location that you want Flarum to be installed in:

 To update Flarum, you'll need to use [Composer](https://getcomposer.org). If you're not familiar with it (although you should be, because you need it to install Flarum), read [our guide](composer.md) for information on what it is and how to set it up.
