What is Hacktoberfest?
Hacktoberfest is an annual, month-long celebration of open source software run by DigitalOcean and DEV, where developers of all skill levels can win one of 50,000 limited edition t-shirts by making four legitimate, non-spammy PRs to ANY (well ok, not literally any, but almost every) open source project on GitHub. While any PR counts, organizations, such as the Stellar Development Foundation, will label specific issues with the Hacktoberfest label, meaning an issue is new contributor friendly.
