+## Code Style and Formatting
+
+Before submitting a Pull Request, please make sure your code matches the project's style guidelines.
+
+### Install `nox`
+
+We use [nox](https://nox.thea.codes/) to run automated sessions like linters and formatters.
+
+Install it using pip:
+
+```bash
+pip install nox
+```
+Then, run the linting session with:
+
+```bash
+nox -s lint
+```
+This command runs the same checks used in the continuous integration (CI) process to ensure your code follows the style conventions of the project.
