Fastlane structure

[yurtpage]

For the F-Droid store it's highly recommended to have a fastlane metadata folder with the app description and screenshots. It also allows to have a translation of a description which is very important.

You can simply merge this now, and build on it any time. See Fastlane Cheat Sheet for guidance if needed, e.g. update the description/screenshots, or add per-release changelogs etc.

Thank you @gjedeer BTW, have you seen the similar app https://f-droid.org/packages/de.nulide.findmydevice/ It's for a different purpose different but maybe it worth to be mentioned in README to help users to chose one that they need most
