-### Precheck
-
-* 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.

 *a smallish microblogging platform, aka the cooler pleroma*

 ## 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.

 If you choose not to install a frontend for whatever reason, it is recommended that you enable [`:static_fe`](#static_fe) to allow remote users to click "view remote source". Don't bother with this if you've got no unauthenticated access though.

 You can also replace the default "no frontend" page by placing an `index.html` file under your `instance/static/` directory.

+## Mastodon-FE
+
+Akkoma supports both [glitchsoc](https://github.com/glitch-soc/mastodon)'s more "vanilla" mastodon frontend,
+as well as [fedibird](https://github.com/fedibird/mastodon)'s extended frontend which has near-feature-parity with akkoma (with quoting and reactions).
+
+To enable either one, you must run the `frontend.install` task for either `mastodon-fe` or `fedibird-fe` (both `--ref akkoma`), then make sure
+`:pleroma, :frontends, :mastodon` references the one you want.

+#### Installing Frontends
+
+Once your backend server is functional, you'll also want to
+probably install frontends.
+
+These are no longer bundled with the distribution and need an extra
+command to install.
+
+For most installations, the following will suffice:
+
+=== "OTP" 
+    ```sh
+    ./bin/pleroma_ctl frontend install pleroma-fe --ref stable
+    # and also, if desired
+    ./bin/pleroma_ctl frontend install admin-fe --ref stable
+    ```
+
+=== "From Source"
+    ```sh
+    mix pleroma.frontend install pleroma-fe --ref stable
+    mix pleroma.frontend install admin-fe --ref stable
+    ```
+
+For more customised installations, refer to [Frontend Management](../../configuration/frontend_management)

 If you opted to allow sudo for the `akkoma` user but would like to remove the ability for greater security, now might be a good time to edit `/etc/sudoers` and/or change the groups the `akkoma` user belongs to. Be sure to restart the akkoma service afterwards to ensure it picks up on the changes.

 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
+
+# We're good, use that URL
+echo "Update URL contents verified"
