 ### Browser
-You can use `vue-chartjs` directly in the browser without any build setup. Like in this [codepen](https://codepen.io/apertureless/pen/vxWbqB?editors=1010). For this case, please use the `vue-chartjs.full.min.js` which is the minified version. It has Vue.js and Chart.js bundled into it. And bundled to a UMD Module. So you only need that one file.

+You can then simply register your component:
+
+```js
+Vue.component('line-chart', {
+  extends: VueChartJs.Line,
+  mounted () {
+    this.renderChart({
+      labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
+      datasets: [
+        {
+          label: 'Data One',
+          backgroundColor: '#f87979',
+          data: [40, 39, 10, 40, 39, 80, 40]
+        }
+      ]
+    }, {responsive: true, maintainAspectRatio: false})
+  }
+})
+```
 
 
 ### Browserify / Webpack 1
 
 If you're using Gulp, Browserify or Webpack 1 the entry is `vue-chartjs.js` which is __transpiled__ and __bundled__ UMD Module.
 
-However Vue.js and Chart.js are `peerDependencies` so you have to install them separately. In most projects you will have `Vue.js` already installed anyways. This way, you can have different versions of Vue.js and Chart.js then in this package.

 ### Webpack 2
 If you're using Webpack 2 it will automatically use the `jsnext:main` / `module` entry point. Which is `es/index.js`
-It is a __transpiled__ es version of the source. And is not __bundled__ to a module. This way you three shaking will work.  Like in the bundled version, `Vue.js` and `Chart.js` are `peerDependencies` and need to be installed.

 ## How to use
 
-You need to import the base chart class and extend it. This gives much more flexibility when working with different data. You can pass the data over props or vue-resource.
+You need to import the component and then either use `extends` or `mixins` and add it.
 
 You can import the whole package or each module individual.
