The French language coordinator of Localization Lab asked us to make the app store descriptions localizable as well.

In Transportr, I just added them to the strings.xml, so they can be translated as part of the other strings.

There, I use fastlane to upload all descriptions with one command after extracting them from the strings.xml file with a script.

Using fastlane has the advantage that the localized descriptions will be picked up by F-Droid automatically as well. Also, it supports taking automated localized screenshots and uploading those as well.
