+# Contributions Guidelines
+
+## Code formatting
+
+Try to follow the existing formatting.
+If there is no existing formatting, you may use `clang-format` with our included `.clang-format` configuration.
+
+In general, in order of importance:
+
+- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
+- Prefer readability over dogma.
+- Keep to the existing formatting.
+- Indent with 4 space unless it's in a submodule.
+- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.
+
+## Signing your work
+
+In an effort to ensure that the code you contribute is actually compatible with the licenses in this codebase, we require you to sign-off all your contributions.
+
+This can be done by appending `-s` to your `git commit` call, or by manually appending the following text to your commit message:
+
+```text
+<commit message>
+
+Signed-off-by: Author name <Author email>
+```
+
+By signing off your work, you agree to the terms below:
+
+```text
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+These terms will be enforced once you create a pull request, and you will be informed automatically if any of your commits aren't signed-off by you.
+
+As a bonus, you can also [cryptographically sign your commits][gh-signing-commits] and enable [vigilant mode][gh-vigilant-mode] on GitHub.
+
+[gh-signing-commits]: https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits
+[gh-vigilant-mode]: https://docs.github.com/en/authentication/managing-commit-signature-verification/displaying-verification-statuses-for-all-of-your-commits
+
+## Backporting to Release Branches
+
+We use [automated backports](https://github.com/PrismLauncher/PrismLauncher/blob/develop/.github/workflows/backport.yml) to merge specific contributions from develop into `release` branches.
+
+This is done when pull requests are merged and have labels such as `backport release-7.x` - which should be added along with the milestone for the release.

-If you want to build PolyMC yourself, check [Build Instructions](https://polymc.org/wiki/development/build-instructions/) for build instructions.

-## Code formatting
-
-Just follow the existing formatting.
-
-In general, in order of importance:
-
-- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
-- Prefer readability over dogma.
-- Keep to the existing formatting.
-- Indent with 4 space unless it's in a submodule.
-- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.

 ## Forking/Redistributing/Custom builds policy
 
-Do whatever you want, we don't care. Just follow the license. If you have any questions about this feel free to ask in an issue.
+You are free to fork, redistribute and provide custom builds as long as you follow the terms of the [license](LICENSE) (this is a legal responsibility), and if you made code changes rather than just packaging a custom build, please do the following as a basic courtesy:
 
-Be aware that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions:
- - [Microsoft Identity Platform Terms of Use](https://docs.microsoft.com/en-us/legal/microsoft-identity-platform/terms-of-use)
- - [CurseForge 3rd Party API Terms and Conditions](https://support.curseforge.com/en/support/solutions/articles/9000207405-curse-forge-3rd-party-api-terms-and-conditions)
-If you do not agree with these terms and conditions, then remove the associated API keys from the [CMakeLists.txt](CMakeLists.txt) file.
+- Make it clear that your fork is not Prism Launcher and is not endorsed by or affiliated with the Prism Launcher project (<https://prismlauncher.org>).
+- Go through [CMakeLists.txt](CMakeLists.txt) and change Prism Launcher's API keys to your own or set them to empty strings (`""`) to disable them (this way the program will still compile but the functionality requiring those keys will be disabled).
+
+If you have any questions or want any clarification on the above conditions please make an issue and ask us.
+
+If you are just building Prism Launcher for your distribution, please make sure to set the `Launcher_BUILD_PLATFORM` to a slug representing your distribution. Examples are `archlinux`, `fedora` and `nixpkgs`.
+
+Note that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions:

+ECMQueryQt
+---------------
+This module can be used to query the installation paths used by Qt.
+
+For Qt5 this uses ``qmake``, and for Qt6 this used ``qtpaths`` (the latter has built-in
+support to query the paths of a target platform when cross-compiling).
+
+This module defines the following function:
+::
+
+    ecm_query_qt(<result_variable> <qt_variable> [TRY])
+
+Passing ``TRY`` will result in the method not making the build fail if the executable
+used for querying has not been found, but instead simply print a warning message and
+return an empty string.
+
+Example usage:
+
+.. code-block:: cmake
+
+    include(ECMQueryQt)
+    ecm_query_qt(bin_dir QT_INSTALL_BINS)
+
+If the call succeeds ``${bin_dir}`` will be set to ``<prefix>/path/to/bin/dir`` (e.g.
+``/usr/lib64/qt/bin/``).
+
+Since: 5.93
