Useful Tips

Here are things to keep in mind when contributing:

  • A contribution can be anything—fixing bugs, creating new features, or updating and writing documentation.
  • Look for a repo's CONTRIBUTING.md file for contribution guidelines and instructions.

Here are tips for creating a good Hacktoberfest issue in your project:

  • Add a CONTRIBUTING.md file with contribution guidelines to your repo.
  • Choose issues that have a well-defined scope and are self-contained.
  • They should serve as good introductions to the codebase.
  • Consider adopting a code of conduct to foster a greater sense of community.
