+## PDF rendering
+
+If you want to use solidtime features that create PDFs, like exporting a report as PDF, you need to configure a PDF rendering server.
+solidtime uses [Gotenberg](https://gotenberg.dev/) to render PDFs.
+The application needs to be able to send requests to the Gotenberg server.
+The self-hosting guide already includes a Gotenberg container.
+The environment variable `GOTENBERG_URL` is used to configure the URL of the Gotenberg server.
+
+```bash
+GOTENBERG_URL=http://gotenberg:3000
+```

 ## Email
 
 Configure the email settings for sending emails. Solidtime supports every (transactional) mail service that offers an SMTP integration.

+More information about the CLI commands can be found in the [CLI commands documentation](../cli-commands).

+```
+
+The command output a random password for the user.
+Afterwards you need to restart the containers:

+```bash
+docker compose down && docker compose up -d
+```
+
+Then you should be able log in with the user you created.
+If the user is a super admin, you can access the super admin panel via `/admin`.
+More information about the super admin panel can be found in the [super admin panel documentation](../super-admin-panel).
