+## Development Practices
+
+### pre-commit
+
+`pre-commit` is a package manager for git hooks that we use during local development.
+
+Current checks are:-
+- requirements.txt library sort and check
+- yaml file check
+- end-of-file must have white line
+- trailing white spaces check
+- `black` library (formats Python code)
+- `isort` library (standardises the order of Python imports)
+- `flake8` library (formats Python code and also improves code style)
+- Jira ticket reference (commits must reference the ticket number)
+
+To override the above for whatever reason (maybe you don't have a ticket number and because you are working on hotfix) you can use the following command.
+
+`PRE_COMMIT_ALLOW_NO_CONFIG=1 git push ...`
+
+### Git commit message
+
+Commit messages should follow the appropriate format.
+All commits must begin with the Jira ticket they are associated with.
+
+format: `ANPL-[int]`
+
+e.g.
+
+`git commit -m "ANPL-1234 insert message here"`
