Git usages that are a bad practice and you should avoid.
- Do not commit directly to the main, release or dev branches.
- Donβt commit files that contain the individual user environment variables (aka. .env/.env.* files).
- Avoid working on multiple issues in the same branch.
- NEVER do a force push.
- Do not edit or delete the last commited message.
