+### Style Guide
+
+The project uses [ruff](https://docs.astral.sh/ruff/) for linting and  formatting.
+Our style configurations are set in the `pyproject.toml` file.
+
+We have a pre-commit hook to run the formatter before you commit, but Ruff can also be [integrated with most editors](https://docs.astral.sh/ruff/editors/setup/) to run automatically.
+
+We recommend you also run the linter before pushing code. 
+
+# Running the linter
+
+We have Makefile commands to run common tasks (Note if you're on Windows you might need to install `make` first, or you can use ruff directly):
+
+This outputs a report of any issues found:
+```shell
+make ruff-check
+```
+
+This command will attempt to fix any issues it can:
+
+⚠️ Warning: This can cause breaking changes. ⚠️
+
+Ensure you check any modifications by this before committing them.
+```shell
+make ruff-fix
+```
+
+**Note:** If you're on Windows you might not have `make` installed by default.
+This is included with [Git for Windows](https://gitforwindows.org/) or you can install make via [Chocolatey](https://chocolatey.org/):
+```shell
+choco install make
+```
+
+**Running directly with ruff**
+
+Alternatively, you can run the commands directly with ruff.
+
+Our rules are quite lenient for general usage, but if you want to explore more rigorous checks you can explore the [ruff documentation](https://docs.astral.sh/ruff/configuration/).
+You can then run checks to see more nuanced errors which you can review manually.
