 cssnext is a CSS transpiler that allows you to use the latest CSS syntax today.
 It transforms CSS specs into more compatible CSS so you don’t need to wait for browser support.

+# This repository contains the PostCSS plugin.
+
+## Why **postcss-cssnext** ? What is the difference with **cssnext** ?
+
+cssnext was at first designed to be a complete tool, before PostCSS became
+popular and so includes some options that does not really belong in a PostCSS
+plugin (options like `import`, `url`, `compress`, `plugins`).
+This days, most people use PostCSS directly so we decided to make integration of
+cssnext more simple by providing a simple (real) plugin.
+
+If you were using cssnext with some options here is what you need to know:
+
+- `import`: just add in your plugins list
+  [postcss-import](https://github.com/postcss/postcss-import)
+- `url`: just add in your plugins list
+  [postcss-url](https://github.com/postcss/postcss-url)
+- `compress`: just add in your plugins list
+  [cssnano](https://github.com/ben-eb/cssnano)
+- `plugins`: just add the plugins directly in your list
+- `messages`: see
+  [postcss-reporter](https://github.com/postcss/postcss-reporter)
+  and
+  [postcss-browser-reporter](https://github.com/postcss/postcss-browser-reporter)
+- `sourcemap`, `map`, `to`, `from`: see
+  [PostCSS source map documentation](https://github.com/postcss/postcss#source-map)
+
+
+## But I like cssnext as it was !
+
+_Don't worry. That's why we created another package._
+**cssnext** package will have a major release soon in order to introduce a minor
+but breaking changes in the Node.js API, but you will get the same tool as
+before.
+The nice thing is: **cssnext** will use **postcss-cssnext** under the hood.
