-## Explanation of Different Builds
-There are three different entry points. It depends on which build setup do you have. The dependencies are bundled or required as a peerDependency.

-- Browser
-- Browserify / Webpack 1
-- Webpack 2

-| Build | Chart.js |
-|---|---|
-| vue-chartjs.full.js | Bundled |
-| vue-chartjs.full.min.js |  Bundled |
-| vue-chartjs.js | peerDependency |
-| vue-chartjs.min.js | peerDependency  |
-| es/index* |  peerDependency |
 
 ### Browser
-You can use `vue-chartjs` directly in the browser without any build setup. Like in this [codepen](https://codepen.io/apertureless/pen/zEvvWM).
