When you go to a github repo, the extension will check for various things on that page and give a score/grade. It is not meant to make the decision for you, it is just a quick assessment.

For the time being it only works on the English version of Github, but we hope to internationalize at some point soon.

Here is some of the criteria we look for.
It is **important** to note that missing some of these is not a huge problem. They add up in total to more than 100% of a possible score. So, one missing can still allow a perfect grade.

- Has License file or section in the README. It is an immediate fail if no license is found.

- Stars count being above 100.
- Has Readme file.
- Most recent commit. Scaled to within a year. 1 year ago being a 0 and now being a 20.
- Amount of contributors being greater than 5.
- Amount of commits.
- Has a sponsors section.
- Has a releases section
- Has docs folder.
- Frequency of commits for root level files and folders. Checks amount of time between most recent and oldest. Also checks for varied dates between and ratio of unique commits.
- Open issues relative to star count or commit count, whichever is greater.
