+ModernFix is a standard Minecraft-style Gradle project powered by Architectury Loom. To build the mod for all platforms,
+run the `build` task (e.g. via `./gradlew build`). You can also use `./gradlew forge:build` or `./gradlew fabric:build`
+to build for just one loader (e.g. when debugging and wanting to rebuild quickly).
+
+You must use Java 17 to develop ModernFix as the toolchain requires it. Nonetheless, the 1.16 mod JARs will work on
+a Minecraft instance with Java 8.

+## Submitting pull requests
+
+Code or documentation contributions are welcome. Please keep the following points in mind:
+
+* This project supports many Minecraft versions. Ideally, contributions should be made to the oldest relevant MC version.
+For instance, a PR optimizing new worldgen should be made to 1.18 (not 1.19 or 1.20) while a PR optimizing something
+like recipes should be made to 1.16 (the oldest supported version).
+
+  This somewhat unconventional policy ensures that all supported versions are treated equal when it comes to development,
+rather than the onus being on other modders and players to backport changes that are needed. Changes to older versions are
+quickly ported up to the latest one as part of the regular development cycle. You are still welcome to open PRs against
+a newer branch if desired - but the change will likely be applied manually and not merged as a regular PR.
+
+* Please ensure your code is reasonably neat and sufficiently documented. Remember that self-documenting code is always
+better.
