-If you want to hack on the GTK+ project, you'll need to have the development
-tools appropriate for your operating system, including:
+# Contribution guidelines
+
+Thank you for considering contributing to the GTK project!
+
+These guidelines are meant for new contributors, regardless of their level
+of proficiency; following them allows the maintainers of the GTK project to
+more effectively evaluate your contribution, and provide prompt feedback to
+you. Additionally, by following these guidelines you clearly communicate
+that you respect the time and effort that the people developing GTK put into
+managing the project.
+
+GTK is a complex free software GUI toolkit, and it would not exist without
+contributions from the free and open source software community. There are
+many things that we value:
+
+ - bug reporting and fixing
+ - documentation and examples
+ - tests
+ - new features
+
+Please, do not use the issue tracker for support questions. If you have
+questions on how to use GTK effectively, you can use:
+
+ - the `#gtk` IRC channel on irc.gnome.org
+ - the [gtk](https://mail.gnome.org/mailman/listinfo/gtk-list) mailing list,
+   for general questions on GTK
+ - the [gtk-app-devel](https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list)
+   mailing list, for questions on application development with GTK
+ - the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
+   mailing list, for questions on developing GTK itself
+
+You can also look at the GTK tag on [Stack
+Overflow](https://stackoverflow.com/questions/tagged/gtk).
+
+The issue tracker is meant to be used for actionable issues only.
+
+## How to report bugs
+
+### Security issues
+
+You should not open a new issue for security related questions.
+
+When in doubt, send an email to the [security](mailto:security@gnome.org)
+mailing list.
+
+### Bug reports
+
+If you're reporting a bug make sure to list:
+
+ 0. which version of GTK are you using?
+ 0. which operating system are you using?
+ 0. the necessary steps to reproduce the issue
+ 0. the expected outcome
+ 0. a description of the behavior; screenshots are also welcome
+ 0. a small, self-contained example exhibiting the behavior; if this
+    is not available, try reproducing the issue using the GTK examples
+    or interactive tests
+
+If the issue includes a crash, you should also include:
+
+ 0. the eventual warnings printed on the terminal
+ 0. a backtrace, obtained with tools such as GDB or LLDB
+
+For small issues, such as:
+
+ - spelling/grammar fixes in the documentation
+ - typo correction
+ - comment clean ups
+ - changes to metadata files (CI, `.gitignore`)
+ - build system changes
+ - source tree clean ups and reorganizations
+
+You should directly open a merge request instead of filing a new issue.
+
+### Features and enhancements
+
+Feature discussion can be open ended and require high bandwidth channels; if
+you are proposing a new feature on the issue tracker, make sure to make
+an actionable proposal, and list:
+
+ 0. what you're trying to achieve
+ 0. prior art, in other toolkits or applications
+ 0. design and theming changes
+
+If you're proposing the integration of new features it helps to have
+multiple applications using shared or similar code, especially if they have
+iterated over it various times.
+
+Each feature should also come fully documented, and with tests.
+
+## Your first contribution
+
+### Prerequisites
+
+If you want to contribute to the GTK project, you will need to have the
+development tools appropriate for your operating system, including:
 
  - Python 3.x
  - Meson
  - Ninja
  - Gettext (19.7 or newer)
- - a C99 compatible compiler
+ - a [C99 compatible compiler](https://wiki.gnome.org/Projects/GLib/CompilerRequirements)

+### Dependencies
 
- * https://wiki.gnome.org/GitLab
+In order to get GTK from Git installed on your system, you need to have the
+required versions of all the software dependencies required by GTK; typically,
+this means a recent version of GLib, Cairo, Pango, and ATK, as well as the
+platform-specific dependencies for the windowing system you are using (Wayland,
+X11, Windows, or macOS).

+ - [Epoxy](https://github.com/anholt/libepoxy)
+ - [ATK](https://gitlab.gnome.org/GNOME/atk)
+ - [Graphene](https://github.com/ebassi/graphene)
+
+GTK will attempt to download and build some of these dependencies if it
+cannot find them on your system.
+
+Additionally, you may want to look at projects that create a development
+environment for you, like [jhbuild](https://wiki.gnome.org/HowDoI/Jhbuild)
+and [gvsbuild](https://github.com/wingtk/gvsbuild).

+
+### Commit messages
+
+The expected format for git commit messages is as follows:
+
+```plain
+Short explanation of the commit
+
+Longer explanation explaining exactly what's changed, whether any
+external or private interfaces changed, what bugs were fixed (with bug
+tracker reference if applicable) and so forth. Be concise but not too

+Closes #1234
+```
+
+ - Always add a brief description of the commit to the _first_ line of
+ the commit and terminate by two newlines (it will work without the
+ second newline, but that is not nice for the interfaces).
+
+ - First line (the brief description) must only be one sentence and
+ should start with a capital letter unless it starts with a lowercase
+ symbol or identifier. Don't use a trailing period either. Don't exceed
+ 72 characters.
+
+ - The main description (the body) is normal prose and should use normal
+ punctuation and capital letters where appropriate. Consider the commit
+ message as an email sent to the developers (or yourself, six months
+ down the line) detailing **why** you changed something. There's no need
+ to specify the **how**: the changes can be inlined.
+
+ - When committing code on behalf of others use the `--author` option, e.g.
+ `git commit -a --author "Joe Coder <joe@coder.org>"` and `--signoff`.
+
+ - If your commit is addressing an issue, use the
+ [GitLab syntax](https://docs.gitlab.com/ce/user/project/issues/automatic_issue_closing.html)
+ to automatically close the issue when merging the commit with the upstream
+ repository:
+
+```plain
+Closes #1234
+Fixes #1234
+Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1234
+```
+
+ - If you have a merge request with multiple commits and none of them
+ completely fixes an issue, you should add a reference to the issue in
+ the commit message, e.g. `Bug: #1234`, and use the automatic issue
+ closing syntax in the description of the merge request.
+
+### Commit access to the GTK repository
+
+GTK is part of the GNOME infrastructure. At the current time, any
+person with write access to the GNOME repository can merge changes to
+GTK. This is a good thing, in that it encourages many people to work
+on GTK, and progress can be made quickly. However, GTK is a fairly
+large and complicated project on which many other things depend, so to
+avoid unnecessary breakage, and to take advantage of the knowledge
+about GTK that has been built up over the years, we'd like to ask
+people committing to GTK to follow a few rules:
+
+0. Ask first. If your changes are major, or could possibly break existing
+   code, you should always ask. If your change is minor and you've been
+   working on GTK for a while it probably isn't necessary to ask. But when
+   in doubt, ask. Even if your change is correct, somebody may know a
+   better way to do things. If you are making changes to GTK, you should
+   be subscribed to the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
+   mailing list; this is a good place to ask about intended changes.
+   The `#gtk` IRC channel on irc.gnome.org is also a good place to find GTK
+   developers to discuss changes, but if you live outside of the EU/US time
+   zones, an email to the gtk-devel mailing list is the most certain and
+   preferred method.
+
+0. Ask _first_.
+
+0. Always write a meaningful commit message. Changes without a sufficient
+   commit message will be reverted.
+
+0. Never push to the `master` branch, or any stable branches, directly; you
+   should always go through a merge request, to ensure that the code is
+   tested on the CI infrastructure at the very least. A merge request is
+   also the proper place to get a comprehensive code review from the core
+   developers of GTK.
+
+If you have been contributing to GTK for a while and you don't have commit
+access to the repository, you may ask to obtain it following the [GNOME account
+process](https://wiki.gnome.org/AccountsTeam/NewAccounts).
