 Decimating your data will achieve the best results. When there is a lot of data to display on the graph, it doesn't make sense to show tens of thousands of data points on a graph that is only a few hundred pixels wide.
 
 There are many approaches to data decimation and selection of an algorithm will depend on your data and the results you want to achieve. For instance, [min/max](https://digital.ni.com/public.nsf/allkb/F694FFEEA0ACF282862576020075F784) decimation will preserve peaks in your data but could require up to 4 points for each pixel. This type of decimation would work well for a very noisy signal where you need to see data peaks.

 - Avoid breaking changes unless there is an upcoming major release, which are infrequent. We encourage people to write plugins for most new advanced features, and care a lot about backwards compatibility.
 - We strongly prefer new methods to be added as private whenever possible. A method can be made private either by making a top-level `function` outside of a class or by prefixing it with `_` and adding `@private` JSDoc if inside a class. Public APIs take considerable time to review and become locked once implemented as we have limited ability to change them without breaking backwards compatibility. Private APIs allow the flexibility to address unforeseen cases.

 # Installation
+
+## Package Manager
+
 Chart.js can be installed via npm or bower. It is recommended to get Chart.js this way.

+### Selecting the Correct Build
+
+Chart.js provides two different builds for you to choose: **Stand-Alone Build**, **Bundled Build**.
+
+#### Stand-Alone Build
+Files:
+* `dist/Chart.js`
+* `dist/Chart.min.js`
+
+The stand-alone build includes Chart.js as well as the color parsing library. If this version is used, you are required to include [Moment.js](https://momentjs.com/) before Chart.js for the functionality of the time axis.
+
+#### Bundled Build
+Files:
+* `dist/Chart.bundle.js`
+* `dist/Chart.bundle.min.js`
+
+The bundled build includes Moment.js in a single file. You should use this version if you require time axes and want to include a single file. You should not use this build if your application already included Moment.js. Otherwise, Moment.js will be included twice which results in increasing page load time and possible version compatibility issues. The Moment.js version in the bundled build is private to Chart.js so if you want to use Moment.js yourself, it's better to use Chart.js (non bundled) and import Moment.js manually.

 You can download the latest version of [Chart.js on GitHub](https://github.com/chartjs/Chart.js/releases/latest).
 
 If you download or clone the repository, you must [build](../developers/contributing.md#building-and-testing) Chart.js to generate the dist files. Chart.js no longer comes with prebuilt release versions, so an alternative option to downloading the repo is **strongly** advised.
