 The above configuration works out of the box for new installations.
 When migrating from a running instance with existing SSH keys from the built-in SSH server to the host SSH server, you need to make sure that the host SSH server is running and that the `gitea_user` has the necessary permissions to access the repository data and the keys (stored in `<gitea_home>/.ssh/`)
 
+NB: To use `git@` as described above, `gitea_user` must be `git` and it does not suffice to set `gitea_ssh_user: git`.
