-* 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.

 ## About 
 
 This is a fork of Pleroma, which is a microblogging server software that can federate (= exchange messages with) other servers that support ActivityPub. What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Akkoma will federate with all servers that implement ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.

 As it currently stands, your OTP build will only be compatible for the specific RedHat distribution you've built it on. Fedora builds only work on Fedora, Centos builds only on Centos, RedHat builds only on RedHat. Secondly, for Fedora, they will also be bound to the specific Fedora release. This is because different releases of Fedora may have significant changes made in some of the required packages and libraries.

+# 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
+
+```
+https://akkoma-updates.s3-website.fr-par.scw.cloud/{branch}/akkoma-{flavour}.zip
+```
+
+Where branch is usually `stable` or `develop`, and `flavour` is
+the one [that you detect on install](../otp_en/#detecting-flavour).
+
+So, for an AMD64 stable install, your update URL will be
+
+```
+https://akkoma-updates.s3-website.fr-par.scw.cloud/stable/akkoma-amd64.zip
+```
+
+To verify the integrity of this file, we have two helper files
+
+```
+# Checksums
+https://akkoma-updates.s3-website.fr-par.scw.cloud/{branch}/akkoma-{flavour}.zip.sha256
+
+# Signify signature of the hashes
+https://akkoma-updates.s3-website.fr-par.scw.cloud/{branch}/akkoma-{flavour}.zip.sha256.sig
+```
+
+Thus, to upgrade manually, with integrity checking, consider the following script:
+
+```bash
+#!/bin/bash
+set -eo pipefail
+
+export FLAVOUR=amd64
+export BRANCH=stable
+
+# Fetch signing key
+curl --silent https://akkoma.dev/AkkomaGang/akkoma/raw/branch/$BRANCH/SIGNING_KEY.pub -o AKKOMA_SIGNING_KEY.pub
+
+# Download zip file and sig files
+wget -q https://akkoma-updates.s3-website.fr-par.scw.cloud/$BRANCH/akkoma-$FLAVOUR{.zip,.zip.sha256,.zip.sha256.sig}
+
+# Verify zip file's sha256 integrity
+sha256sum --check akkoma-$FLAVOUR.zip.sha256
+
+# Verify hash file's integrity
+# Signify might be under the `signify` command, depending on your distribution
+signify-openbsd -V -p AKKOMA_SIGNING_KEY.pub -m akkoma-$FLAVOUR.zip.sha256
