-# Contribution Guidelines
-
-1. All commits need a sign-off by the author (except for drafts)
-   If additional reviewers gave their ack, a proper attribution
-   header may be added.
-
-2. Commit messages should explain what's really done here and their
-   headlines need a short an precise subject. See history for examples.
-
-   Keep in mind that history is also a piece of documentation.
-
-3. Once release is out, bugfixes should be submitted separately, against
-   the affected release branch(es) as well as master (so multiple pull requests)
-
-4. If new functions or types are introduced, these should be documented
-   in-code, so we can generate docs directly from the code :)
-
-5. Use pull request tags if you can - if we need some more, just ask.

-XLibre Xserver
-===============
+X Server
+--------
 
-Xlibre is a fork of the [Xorg Xserver](https://gitlab.freedesktop.org/xorg/xserver)
-with lots of code cleanups and enhanced functionality.
+The X server accepts requests from client applications to create windows,
+which are (normally rectangular) "virtual screens" that the client program
+can draw into.
 
-This fork was necessary since toxic elements within Xorg projects, moles
-from BigTech, are boycotting any substantial work on Xorg, in order to
-destroy the project, to eliminate competition of their own products.
-Classic "embrace, extend, extinguish" tactics.
+Windows are then composed on the actual screen by the X server
+(or by a separate composite manager) as directed by the window manager,
+which usually communicates with the user via graphical controls such as buttons
+and draggable titlebars and borders.
 
-Right after journalists first began covering the planned fork Xlibre,
-on June 6th 2025, Redhat employees started a purge on the Xlibre founder's
-GitLab account on freedesktop.org: deleted the git repo, tickets, merge
-requests, etc, and so fired the shot that the whole world heard.
+For a comprehensive overview of X Server and X Window System, consult the
+following article:
+https://en.wikipedia.org/wiki/X_server
 
-This is an independent project, not at all affiliated with BigTech or any
-of their subsidiaries or tax evasion tools, nor any political activists
-groups, state actors, etc. It's explicitly free of any "DEI" or similar
-discriminatory policies. Anybody who's treating others nicely is welcomed.
+All questions regarding this software should be directed at the
+Xorg mailing list:
 
-It doesn't matter which country you're coming from, your political views,
-your race, your sex, your age, your food menu, whether you wear boots or
-heels, whether you're furry or fairy, Conan or McKay, comic character, a
-small furry creature from Alpha Centauri, or just a boring average person.
-Anybody who's interested in bringing X forward is welcome.
+  https://lists.freedesktop.org/mailman/listinfo/xorg
 
-Together we'll make X great again!
+The primary development code repository can be found at:
 
-Upgrade notice
---------------
+  https://gitlab.freedesktop.org/xorg/xserver
 
-* Module ABIs have changed - drivers MUST be recompiled against this Xserver
-  version, otherwise the Xserver can crash or fail to start up correctly.
+For patch submission instructions, see:
 
-* If your console is locked up (no input possible, not even VT switch), then
-  most likely the input driver couldn't be loaded due to a version mismatch.
-  When unsure, it's best to be prepared to ssh into your machine from another one
-  or set a timer that's calling `chvt 1` after certain time, so you don't
-  need a cold reboot.
-  Or, make sure that you have magic `SysRq` key enabled (`Alt+PrtSc`)
-  via sysctl (`kernel.sysrq=1`), then press following combination depending on keyboard
-  layout to make kernel regain control over keyboard to make VT switching work:
-  - QWERTY/AZERTY keyboard layout: `SysRq + R`
-  - Dvorak/Colemak keyboard layout: `SysRq + P`
+  https://www.x.org/wiki/Development/Documentation/SubmittingPatches
 
-* Proprietary Nvidia drivers might break: they still haven't managed to do
-  even simple cleanups to catch up with Xorg master for about a year.
-  All attempts to get into direct mail contact have failed. We're trying to
-  work around this, but cannot give any guarantees. But you can make it work
-  by adding `Option "IgnoreABI" "1"` line to `ServerFlags` section in Xorg config.
+As with other projects hosted on freedesktop.org, X.Org follows its
+Code of Conduct, based on the Contributor Covenant. Please conduct
+yourself in a respectful and civilized manner when using the above
+mailing lists, bug trackers, etc:
 
-* Most Xorg drivers should run as-is (once recompiled!), with some exceptions.
-  See `.gitlab-ci.yml` for the versions/branches built along with Xlibre.

-Driver repositories
--------------------
-
-Since Redhat had deleted and banned all X11Libre repositories from freedesktop.org,
-the driver repositories are now moved to GitHub:
