+## Generate users.yml
+
+Dozzle supports generating `users.yml` file. This file is used to authenticate users. Here is an example:
+
+```sh
+docker run amir20/dozzle generate admin --password password --email test@email.net --name "John Doe" > users.yml
+```
+
+In this example, `admin` is the username. Email and name are optional but recommended to display accurate avatars. `docker run amir20/dozzle generate --help` displays all options.
+
+| Flag         | Description     | Default |
+| ------------ | --------------- | ------- |
+| `--password` | User's password |         |
+| `--email`    | User's email    |         |
+| `--name`     | User's fullname |         |
+
+See [authentication](/guide/authentication) for more information.
+
+## Agent Mode
+
+Dozzle supports running in agent mode. Agent mode is useful when running Dozzle on a remote host and you want to monitor a different Docker host. Agent mode is enabled by setting the `--remote-agent` flag. Here is an example:
+
+```sh
+docker run --volume=/var/run/docker.sock:/var/run/docker.sock -p 8080:8080 amir20/dozzle --remote-agent remote-ip:7007
+```
+
+| Flag     | Env Variable        | Default |
+| -------- | ------------------- | ------- |
+| `--addr` | `DOZZLE_AGENT_ADDR` | `:7007` |
+
+See [agent](/guide/agent) for more information.
+
+## Healtcheck
+
+Dozzle supports healthcheck using `dozzle healthcheck` command. It is not enabled by default as it adds extra CPU usage. To use `healthcheck` you need to configure it.
+
+See [healthcheck](/guide/healthcheck) for more information.
