In the “Summit for Lemmy” app, if you go to a community that you moderate, click on the three dots in the bottom right corner:

then when the Community options pops up:

tap on “Community Info”:

Which will give you the “Unsubscribe” / “Instance Info” options, as well as the community Header/Profile Image, Description, Stats, etc.

If you then tap the three dots in the bottom right corner, you end up with the option to edit /delete the community.

PLEASE add a feature similar to the Community Edit/Delete for Voyager.
