Hi Kaleb
This is possible, yes. No attribution is needed if you're linking to
devdocs.io or opening
devdocs.io (unaltered) within your application (and that is not the primary feature of your app).
However, if you're repackaging DevDocs with a different UI, then you need to follow the terms of the
MPL license for any code that you re-use from DevDocs (e.g. license any derivative code under MPL and tell your users where they can download the code), and attribute all content to DevDocs /
devdocs.io.
Hope that answers your question.
