confused about docs

Hi, thank you for your code. I'm a bit confused by your docs and demos, though.

• In demo I find a 'precision' option passed to this plugin. This is not mentioned in your docs.

    .pipe(
      gulpPostcss([
        easingGradient({
          // Default settings
          precision: 0.1,
          alphaDecimals: 5,
        }),
      ])

• In demo pcss I found:

background: linear-gradient(to right, green, steps(4, skip-none), red);

What's steps? it's not standard css syntax, If I'm not wrong..

Could you please exaplain and/or update your docs and demos?

Start by comparing the documented options with the demo's precision setting, then inspect the demo CSS containing steps(4, skip-none). Done means the documentation explains both items clearly or the demos are updated to match the documented behavior.
