+
+- **Pre-Commit Checks** - Optional, but **highly recommended**, for helping to identify simple issues before committing. (trailing-whitespace, end-of-file-fixer, check-yaml, yamlfmt, yamllint)
+    - Installation
+        - Virtual Environment Route
+            - It is recommended to create a virtual env for your repo (`python3 -m venv venv`)
+            - Install the required pip packages (`pip install -r requirements.txt`)
+            - Continue to the "Install `pre-commit` Hooks"
+        - `pre-commit` Only Route
+            - [Install pre-commit](https://pre-commit.com/#install) (`pip install pre-commit`)
+        - Install `pre-commit` Hooks
+            - To install the pre-commit script: `pre-commit install`
+    - Usage & Useful `pre-commit` Commands
+        - After staging your files with `git`, to run the pre-commit script on changed files: `pre-commit run`
