+We use `pre-commit` hooks to ensure consistent development standards are maintained, and encourage any contributors to ensure `pre-commit` is installed prior to committing any changes to your branch. You can read the `pre-commit` docs [here](https://pre-commit.com).

+`pre-commit` is installed as a dev dependency in QREF, but prior to committing any changes you must run:
+```bash
+poetry run pre-commit install

+```bash
+poetry run pre-commit run --all
+```
+This command will print a summary of the current code quality in your branch.
