Rules
To earn your Hacktoberfest tee or tree reward, you must register and make four valid pull requests (PRs) between October 1-31 (in any time zone). PRs can be made to participating public repos on GitHub, those that have the Hacktoberfest topic. If a maintainer reports your pull request as spam or behavior not in line with the project’s code of conduct, you will be ineligible to participate. This year, the first 70,000 participants who successfully complete the challenge will be eligible to receive a prize.
