Download Sideloader from this repo's releases https://github.com/Dadoum/Sideloader. The dependencies are libimobiledevice and libplist-2.X (The exact name differs between distros)
In the install via AltServer step, use Sideloader instead, login with the burner apple account you created (I logged in with it as an icloud calendar account)
Just after installing Sidestore, refresh it after doing anything else. This is for switching the signature from your desktop computer to the Sidestore self signed one.
To add the AltStore repo, open the Sidestore app, go to Browse > Sources > + Button and type https://apps.altstore.io. Check the other ones if you feel like it.
You can keep the WireGuard loopback VPN off unless you need to install apps or refresh with Sideloader. You only need it on for these both tasks.
To install apps that are outside of the repos, like Aidoku, download the IPA file and place it inside the SideStore folder in your iPhone file explorer. Then tap it so it's opened in Sidestore and installed. Otherwise it will throw an error saying it isn't found.
