 # Database Preparation
 
-You need a database to use Gitea. Gitea supports PostgreSQL (>=10), MySQL (>=5.7), MariaDB, SQLite, and MSSQL (>=2008R2 SP3). This page will guide into preparing database. Only PostgreSQL and MySQL will be covered here since those database engines are widely-used in production. If you plan to use SQLite, you can ignore this chapter.

 Database instance can be on same machine as Gitea (local database setup), or on different machine (remote database).

 # 数据库准备
 
-在使用 Gitea 前，您需要准备一个数据库。Gitea 支持 PostgreSQL（>=10）、MySQL（>=5.7）、SQLite 和 MSSQL（>=2008R2 SP3）这几种数据库。本页将指导您准备数据库。由于 PostgreSQL 和 MySQL 在生产环境中被广泛使用，因此本文档将仅涵盖这两种数据库。如果您计划使用 SQLite，则可以忽略本章内容。
