 ## Setup
 
+We currently only support building and running the server on Windows. Linux and Mac will be supported before UE5 release

 To build the code you will need Visual Studio 2019 (we use c++20 features), git and vcpkg.
 
 * Install Visual Studio 2019 Version 16.9.4 or later (16.10 is recommended as it contains improvements to debug codegen which have a pretty significant impact when iterating in debug mode)

+# Contributing Code
+
+We rely on clang-format for consistent code formatting. You can install version 12 or later from https://llvm.org/builds/
+
+The helper scripts also depend on Python 3.x, which you may install from https://www.python.org/downloads/windows/
+
+Once you have those dependencies, you can simply run `prepare_commit.bat` to ensure the code is properly formatted and has the Epic copyright header comment
