 This generator allows to build images for both Arch Linux and Debian Testing, you can replace `<sysid>` by either `arch` or `debian` in the following examples. Note that mkosi may require tools that are not available on your distribution.
 
+First:
+- Put your SSH public key in `root/.ssh/authorized_keys`
+- Put a SFTPGo binary as `usr/local/bin/sftpgo`
+
 You can generate a new image in `/var/lib/machines/servnest-<sysid>` by running `mkosi --force -d <sysid>` from this repository (`--force` erases an already existing image).
 
 You need to copy `mkosi.nspawn` into `/etc/systemd/nspawn/servnest-<sysid>.nspawn` to allow the container to use network without restrictions.
 
 You can then boot the container:
-```
+```shell
 machinectl start servnest-<sysid>
 machinectl shell servnest-<sysid>
 ```
