By submitting this pull request I confirm I've read and complied with the below requirements 🖖

Please read it multiple times. I spent a lot of time on these guidelines and most people miss a lot.

Requirements for your pull request

• [✅ ] Don't open a Draft / WIP pull request while you work on the guidelines. A pull request should be 100% ready and should adhere to all the guidelines when you open it. Instead use #2242 for incubation visibility.

  Try to prioritize unreviewed PRs, but you can also add more comments to reviewed PRs. Go through the below list when reviewing. This requirement is meant to help make the Awesome project self-sustaining. Comment here which PRs you reviewed. You're expected to put a good effort into this and to be thorough. Look at previous PR reviews for inspiration. Just commenting “looks good” or simply marking the pull request as approved does not count! You have to actually point out mistakes or improvement suggestions. Comments pointing out lint violation are allowed, but does not count as a review.

  • A code license like MIT, BSD, Apache, GPL, etc, is not acceptable. Neither are WTFPL and Unlicense.
  • Place a file named license or LICENSE in the repo root with the license text.
  • Do not add the license name, text, or a Licence section to the readme. GitHub already shows the license name and link to the full text at the top of the repo.
  • To verify that you've read all the guidelines, please comment on your pull request with just the word unicorn.
• [✅ ] Has contribution guidelines.
  • The file should be named contributing.md. The casing is up to you.

  • The section should not appear in the Table of Contents.
• [✅ ] All non-important but necessary content (like extra copyright notices, hyperlinks to sources, pointers to expansive content, etc) should be grouped in a Footnotes section at the bottom of the readme. The section should not be present in the Table of Contents.
• [ ✅ ] Has consistent formatting and proper spelling/grammar.
  • The link and description are separated by a dash.
    Example: - [AVA](…) - JavaScript test runner.
  • The description starts with an uppercase character and ends with a period.

  You can still use a CI for linting, but the badge has no value in the readme.
