Hi there @mshelomi!
Please see this quote from @Mehrbod_Estaki, from your last topic on this forum:
Specifically, the link to the metadata guide at the bottom. In general though I would recommend you take a step back and review the documentation and tutorials we have put together at docs.qiime2.org --- the fundamental ideas behind QIIME 2 are described in great detail there, and will hopefully steer you in the right direction, generally speaking. As always, we are here to help!
Thanks! :qiime2:
