The `package` line is the one that actually alters the system. Until Pyruse is packaged for your operating system, you may want to change this line to `checkinstall package`. [Checkinstall](https://en.wikipedia.org/wiki/CheckInstall) should be able to turn your Pyruse installation into a native Linux package.
Then, to run Pyruse, start (and enable) `pyruse.service`.
If you use nftables bans, you should also start (and enable) `pyruse-boot@action_nftBan.service`.
