• I have read and understood the [instructions for creating a list](https://github.com/sindresorhus/awesome/blob/master/create-list.md).
• This pull request has a descriptive title in the format Add Name of List (Example: Add Swift), not Update readme.md or Add awesome list.
• The entry in the Awesome list should:
  • Include a short description about the project/theme of the list. It should not describe the list itself.
    Example: - [Fish](…) - User-friendly shell., not - [Fish](…) - Resources for Fish..
  • Be added at the bottom of the appropriate category.
• The list I'm submitting complies with the below requirements.

Requirements for your Awesome list

• Has been around for at least 30 days.
  That means 30 days from either the first real commit or when it was open-sourced. Whatever is most recent.
• It's the result of hard work and the best I could possibly produce.
• Non-generated Markdown file in a GitHub repo.
• Includes a succinct description of the project/theme at the top of the readme. (Example)
• The repo should have awesome-list & awesome as GitHub topics. I encourage you to add more relevant topics.
• Not a duplicate.
• Only has awesome items. Awesome lists are curations of the best, not everything.
• Includes a project logo/illustration whenever possible.
  • Either centered, fullwidth, or placed at the top-right of the readme. (Example)
  • The image should link to the project website or any relevant website.
  • The image should be high-DPI. Set it to maximum half the width of the original image.
• Entries have a description, unless the title is descriptive enough by itself. It rarely is though.
• Includes the Awesome badge.
  • Should be placed on the right side of the readme heading.
    • Can be placed centered if the list has a centered graphics header.
  • Should link back to this list.
• Has a Table of Contents section.
  • Should be named Contents, not Table of Contents.
  • Should be the first section in the list.
  • Should only have one level of nested lists, preferably none.
• Has an appropriate license.
  • That means something like CC0, not a code licence like MIT, BSD, Apache, etc.
  • WTFPL and Unlicense are not acceptable licenses.
  • If you use a license badge, it should be SVG, not PNG.
• Has contribution guidelines.
  • The file should be named contributing.md. Casing is up to you.
• 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.
  • Consistent and correct naming. For example, Node.js, not NodeJS or node.js.
• Doesn't include a Travis badge.
  You can still use Travis for list linting, but the badge has no value in the readme.

Go to the top and read it again.
