+            │ RELEASE NOTES for FFmpeg 5.1 "Riemann" LTS │
+            └────────────────────────────────────────────┘
+
+   The FFmpeg Project proudly presents FFmpeg 5.1 "Riemann" LTS, about 6
+   months after the release of FFmpeg 5.0, our first Long Term Support
+   release. While several past FFmpeg releases have enjoyed long term
+   support, this is the first release where such an intention is made
+   clear at release.
+
+   A complete Changelog is available at the root of the project, and the
+   complete Git history on https://git.ffmpeg.org/gitweb/ffmpeg.git
+
+   We hope you will like this release as much as we enjoyed working on it, and
+   as usual, if you have any questions about it, or any FFmpeg related topic,
+   feel free to join us on the #ffmpeg IRC channel (on irc.libera.chat) or ask
+   on the mailing-lists.

+@chapter gpg key generation
+
+If you have no gpg key yet, we recommend that you create a ed25519 based key as it
+is small, fast and secure. Especially it results in small signatures in git.
+
+@example
+gpg --default-new-key-algo "ed25519/cert,sign+cv25519/encr" --quick-generate-key "human@@server.com"
+@end example
+
+When generating a key, make sure the email specified matches the email used in git as some sites like
+github consider mismatches a reason to declare such commits unverified. After generating a key you
+can add it to the MAINTAINER file and upload it to a keyserver.
