As demonstrated in the example above basic knowledge of `html` and [JSON](https://en.wikipedia.org/wiki/JSON) syntax is enough to get started i.e. with/without JavaScript!

 ### Un-minified versions are also available on CDN
+
 While non-minified source files may contain characters outside UTF-8, it is recommended that you specify the `charset` when loading those bundles.

 ```html

 > Please note that as of v2 the "plotly-latest" outputs (e.g. https://cdn.plot.ly/plotly-latest.min.js) will no longer be updated on the CDN, and will stay at the last v1 patch v1.58.5. Therefore, to use the CDN with plotly.js v2 and higher, you must specify an exact plotly.js version.
 
 ### MathJax

 You could load either version two or version three of MathJax files, for example:

 ### Need to have several WebGL graphs on a page?
+
 You may simply load [virtual-webgl](https://github.com/greggman/virtual-webgl) script for WebGL 1 (not WebGL 2) before loading other scripts.

 ## Bundles
+
 There are two kinds of plotly.js bundles:
+
 1. Complete and partial official bundles that are distributed to `npm` and the `CDN`, described in [the dist README](https://github.com/plotly/plotly.js/blob/master/dist/README.md).
 2. Custom bundles you can create yourself to optimize the size of bundle depending on your needs. Please visit [CUSTOM_BUNDLE](https://github.com/plotly/plotly.js/blob/master/CUSTOM_BUNDLE.md) for more information.

-## Alternative ways to load and build plotly.js
-If your library needs to bundle or directly load [plotly.js/lib/index.js](https://github.com/plotly/plotly.js/blob/master/lib/index.js) or parts of its modules similar to [index-basic](https://github.com/plotly/plotly.js/blob/master/lib/index-basic.js) in some other way than via an official or a custom bundle, or in case you want to tweak the default build configurations, then please visit [`BUILDING.md`](https://github.com/plotly/plotly.js/blob/master/BUILDING.md).
