Contributing

If you want to add a project to this list, please make sure that:

• You read the contributing guide
• The repository has hacktoberfest as a topic and counts for the hacktoberfest event
• The project can't be just an "add your name" or simply +1 contribution to hacktoberfest
• Place them in alphabetical order
• One repository per PR/contribution - avoid conflicts and simplify review
• Your pull request is not spammy, just adding an empty line; otherwise, it will be marked as invalid and not count towards hacktoberfest.

If they meet the requirements above, feel free to create a PR. Happy Hacking! ✨
