   - SMTP family, if your provider does not explicitly say which protocol it uses but does provide a port, you can set SMTP_PORT instead and this will be inferred.

 # 配置说明
 
-这是针对Gitea配置文件的说明，你可以了解Gitea的强大配置。需要说明的是，你的所有改变请修改 `custom/conf/app.ini` 文件而不是源文件。所有默认值可以通过 [app.example.ini](https://github.com/go-gitea/gitea/blob/master/custom/conf/app.example.ini) 查看到。如果你发现 `%(X)s` 这样的内容，请查看 [ini](https://github.com/go-ini/ini/#recursive-values) 这里的说明。标注了 :exclamation: 的配置项表明除非你真的理解这个配置项的意义，否则最好使用默认值。
