+# 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:
+
+```
+<commit message>
+
+Signed-off-by: Author name <Author email>
+```
+
+By signing off your work, you agree to the terms below:
+
+    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

+        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.

+- Make it clear that your fork is not PolyMC and is not endorsed by or affiliated with the PolyMC project (https://polymc.org).
+- Go through [CMakeLists.txt](CMakeLists.txt) and change PolyMC'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).

+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
