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

Example of checkbox-indeterminate mdl2-checkbox-indeterminate 
<i class="mdl2 mdl2-checkbox-indeterminate" aria-hidden="true"></i>

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