Hi @sooni,
Before addressing your question, I want to bring the code of conduct to your attention - specifically the section on patience. Please remember that all of our forum moderators offer our assistance for free, and we will follow up with you as soon as we are able. Please keep this in mind for future replies, and do not double post any of your questions. Thanks for your understanding and cooperation! 
As @cherman2 mentioned, we do not have a formal tutorial on our shotgun distribution of QIIME 2, as these plugins are still in an alpha release. You can find more information on this distribution in this forum post. For particular commands for functional analysis, please take a look at the link @cherman2 provided for q2-moshpit.
Cheers
