-### Fonts and Font Images
-
-More than just a script tag is needed for this component to work. You will also need a 'fnt', font image file, and to pass the paths to these files with 'fnt' and 'fntImage' properties.
-
-```html
-<a-entity bmfont-text="text: Hello World; width: 1000; fnt:../fonts/DejaVu-sdf.fnt; fntImage:../fonts/DejaVu-sdf.png">
-</a-entity>
-```
-
-Since the paths "../fonts/DejaVu-sdf.fnt" and "../fonts/DejaVu-sdf.png" are set by default, it is possible to avoid declaring them explicitly by using the DejaVu font and organizing your project folders to match the defaults.
-
-It should be possible to use different fonts, but I have yet to try. A guide for generating SDF fonts can be found [here](https://github.com/libgdx/libgdx/wiki/Distance-field-fonts).

 To be honest, I'm not sure what units width uses as it is not specified by three-bmfont-text. You will have to play around a bit.
 
+### Fonts and Font Images

+Custom fonts can be specified with 'fnt' and 'fntImage' properties.

+These default to hosted "DejaVu-sdf.fnt" and "DejaVu-sdf.png" files thanks to RawGit.

 ### Advanced Usage
 
 This component does not make use of all of the features of [three-bmfont-text](https://github.com/Jam3/three-bmfont-text) and its sister modules, if you require more advanced functionality such as tabSize and start and end indices, I recommend forking this component and modifying it. Pull requests are welcome, but please include a test example.
