(Optionally): If you want to install any additional add-ons, repeat the sideload steps above for those packages in sequence.
Note: Additional add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that saysSignature verification failed

We strongly advise you to opt out of installing these, as they may cause your device to bootloop,
as well as attempt to access or corrupt your data.
