GradeD

A workable base with real gaps. Start with setup instructions and issue and PR templates.

Top 49% of 5,156 graded repos

A low grade is a to-do list, not a judgment of your code

Most gaps here are documentation, tests, and setup, not the code itself. Closing your top 3 gaps alone would lift this repo to B (85).
