- For a small change, just send a PR.
- For bigger changes open an issue for discussion before sending a PR.
- PR should have:
- Test case
- Documentation
- Example (If it makes sense)
- You can also contribute by:
- Reporting issues
- Suggesting new features or enhancements
- Improve/fix documentation
