+# Naming Conventions
+
+The naming conventions for Zen are intended to remain close to the Unreal Engine coding style, with some minor exceptions wrt prefixes.
+
+* Classes/Structs - `PascalCase`
+* Functions - `PascalCase()`
+* Class member variables - `m_PascalCase`
+* Global variables - `g_PascalCase`
+* Static variables - `s_PascalCase`
+* Thread local variables - `t_PascalCase`
+
+Those who are familiar with the UE coding standards will note that we do not require or encourage `F` prefixes on struct or classes, and we expect class members to have a `m_` member prefix.
+
+# Code formatting
+
+To ensure consistent formatting we rely on `clang-format` to automatically format source code. This leads to consistent formatting which should lead to fewer surprises and more straightforward merging.
+
+Formatting is ensured by using [pre-commit](https://pre-commit.com/)
+
+- [Ensure you have a Python install](https://www.python.org/downloads/) and that Python has been added to the PATH environment variable
+- [Install pre-commit](https://pre-commit.com/#installation) so it is available in PATH
+- Run pre-commit manually on staged files `pre-commit run`
+- Run pre-commit manually on all files `pre-commit run --all-files`
+- Install git commit hooks `pre-commit install`, which will automatically run before every commit.
