-* For support use https://git.pleroma.social/pleroma/pleroma-support or [community channels](https://git.pleroma.social/pleroma/pleroma#community-channels).
-* Please do a quick search to ensure no similar bug has been reported before. If the bug has not been addressed after 2 weeks, it's fine to bump it.
-* Try to ensure that the bug is actually related to the Pleroma backend. For example, if a bug happens in Pleroma-FE but not in Mastodon-FE or mobile clients, it's likely that the bug should be filed in [Pleroma-FE](https://git.pleroma.social/pleroma/pleroma-fe/issues/new) repository.

+# Verifying OTP release integrity
+
+All stable OTP releases are cryptographically signed, to allow
+you to verify the integrity if you choose to.
+
+Releases are signed with [Signify](https://man.openbsd.org/signify.1),
+with [the public key in the main repository](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/SIGNING_KEY.pub)
+
+Release URLs will always be of the form

+
+Where branch is usually `stable` or `develop`, and `flavour` is

+
+```
+https://akkoma-updates.s3-website.fr-par.scw.cloud/stable/akkoma-amd64.zip
