After you get up and running, you can place MDL2 icons just about anywhere with the <i> tag:

Example of all-apps mdl2-all-apps 
<i class="mdl2 mdl2-all-apps" aria-hidden="true"></i>

Note: to improve web accessibility, we recommend using aria-hidden="true" to hide icons used purely for decoration.
