+# postcss-url [![Build Status](https://travis-ci.org/postcss/postcss-url.png)](https://travis-ci.org/postcss/postcss-url)
+
+> [PostCSS](https://github.com/postcss/postcss) plugin to rebase or inline on url().
+
+## Installation
+
+    $ npm install postcss-url
+
+## Usage
+
+```js
+// dependencies
+var fs = require("fs")
+var postcss = require("postcss")
+var url = require("postcss-url")
+
+// css to be processed
+var css = fs.readFileSync("input.css", "utf8")
+
+// process css
+var output = postcss()
+  .use(url({
+    url: "rebase" // or "inline"
+  }))
+  .process(css, {
+    // "rebase" mode need at least one of those options
+    // "inline" mode might need `from` option only
+    from: "src/stylesheet/index.css"
+    to: "dist/index.css"
+  })
+  .css
+```
+
+Checkout [tests](test) for examples.
+
+### Options
+
+#### `url` (default: `"rebase"`)
+
+##### `url: "rebase"`
+
+Allow you to fix `url()` according to postcss `to` and/or `from` options (rebase to `to` first if available, otherwise `from` or `process.cwd()`).
+
+##### `url: "inline"`
+
+Allow you to inline assets using base64 syntax. Can use postcss `from` option to find ressources.
