 # DOM Distiller
 
 DOM Distiller aims to provide a better reading experience by distilling the
 content of the page. This distilled content can then be used in a variety of
 ways.
 
 The current efforts that are or will be powered by DOM Distiller:
 
 -   Reader mode: a mobile-friendly viewing mode for Chrome mobile
 -   [Simplify page for print]

 -   Choose "Appears to be an article" to turn on Reader mode for
     non-mobile-friendly long articles, or choose "Always" for debugging.
 -   Click "Relaunch Now" at the bottom of the page
 -   Next time you're trying to read a page, tap on the "Make page
     mobile-friendly" infobar to try it out!

 # Get the code
 
 In a folder where you want the code (outside of the chromium checkout):
 
 ```bash
 git clone https://github.com/chromium/dom-distiller.git
 ```
 
 A `dom-distiller` folder will be created in the folder you run that command.

 aliases for easy access later. For example, Nexus 4 would be:

 Steps 1-3 in the guide above can typically be done in a stable version of
 Chrome, whereas the rest of the steps is typically done in your own build of
 Chrome (hence the "(Re)" in step 4). Besides speed, this also facilitates
 side-by-side comparison.
