@jlarmstrongiv Thank you for creating the pull request. LGTM 👍🏼

It might be better if we could add an example using the fix option, but I want to hear @jeddy3's idea.

@jlarmstrongiv Thanks for the pull request.

I've requested some changes.

As @ybiquitous suggested, lets add an "Example H". Something along the lines of:

---

Example H

Using a string and the fix option:

stylelint
  .lint({
    code: "a { color: pink; }",
    config: { rules: { "hue-degree-notation": "angle" } },
    fix: true
  })
  .then(function () {
    /* .. */
  });

The autofixed code will be available as the value of the output property in the returned object.

@jlarmstrongiv Thanks for making those changes.

I've added two minor nits suggestions.

Let's also update the options page as detailed in #5971 (comment)

@jeddy3 thank you! Should be all set 🤞

[jeddy3]

Thanks for making the changes.

Almost there... the markdown is lost when copying and pasting.

Two suggestions are to add the link and backticks back in.
