Restructure documentation. Now the documentation has installation, administration, usage, development, contributing the 5 main parts (#23629)

- **Installation**: includes how to install Gitea and related other
tools, also includes upgrade Gitea
- **Administration**: includes how to configure Gitea, customize Gitea
and manage Gitea instance out of Gitea admin UI
- **Usage**: includes how to use Gitea's functionalities. A sub
documentation is about packages, in future we could also include CI/CD
and others.
- **Development**: includes how to integrate with Gitea's API, how to
develop new features within Gitea
- **Contributing**: includes how to contribute code to Gitea
repositories.

After this is merged, I think we can have a sub-documentation of `Usage`
part named `Actions` to describe how to use Gitea actions

+## 反向代理认证
+
+Gitea 支持通过读取反向代理传递的 HTTP 头中的登录名或者 email 地址来支持反向代理来认证。默认是不启用的，你可以用以下配置启用。
+
+```ini
+[service]
+ENABLE_REVERSE_PROXY_AUTHENTICATION = true
+```
+
+默认的登录用户名的 HTTP 头是 `X-WEBAUTH-USER`，你可以通过修改 `REVERSE_PROXY_AUTHENTICATION_USER` 来变更它。如果用户不存在，可以自动创建用户，当然你需要修改 `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true` 来启用它。
+
+默认的登录用户 Email 的 HTTP 头是 `X-WEBAUTH-EMAIL`，你可以通过修改 `REVERSE_PROXY_AUTHENTICATION_EMAIL` 来变更它。如果用户不存在，可以自动创建用户，当然你需要修改 `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true` 来启用它。你也可以通过修改 `ENABLE_REVERSE_PROXY_EMAIL` 来启用或停用这个 HTTP 头。
+
+如果设置了 `ENABLE_REVERSE_PROXY_FULL_NAME=true`，则用户的全名会从 `X-WEBAUTH-FULLNAME` 读取，这样在自动创建用户时将使用这个字段作为用户全名，你也可以通过修改 `REVERSE_PROXY_AUTHENTICATION_FULL_NAME` 来变更 HTTP 头。
+
+你也可以通过修改 `REVERSE_PROXY_TRUSTED_PROXIES` 来设置反向代理的IP地址范围，加强安全性，默认值是 `127.0.0.0/8,::1/128`。 通过 `REVERSE_PROXY_LIMIT`， 可以设置最多信任几级反向代理。
+
+注意：反向代理认证不支持认证 API，API 仍旧需要用 access token 来进行认证。
