What is Hacktoberfest?
"Hacktoberfest is a month-long celebration of open source software." - DigitalOcean
Hacktoberfest is open to everyone. For the official limited edition Hacktoberfest shirt, you must register and make four pull requests in the month of October (to a repository with the hacktoberfest label) - you can even contribute to this repository! You can sign up at hacktoberfest.digitalocean.com.
Hacktoberfest® encourages participation in the open source community.
In all of the hacktoberfest excitement, many companies want to join the celebration by rewarding their contributors with even more swag! That's why we're here!
The purpose of this list is to incentivise meaningful contributions. If you intend to make low-value changes -- just for swag. Don't.
