We use your address to send the edition and nothing else. Confirm by email, leave in one click. How we handle it.
Suggest a repository
Any public GitHub repository, any size. If it is your own, that is welcome too. We read every suggestion, and some picks are made at random, so stars do not decide. Whatever we pick goes through the same checks as every other entry, and the review is written either way.
Thanks — it is in.
Every suggestion is read. The ones we pick appear in an edition, credited to you if you left a name.
