This is a bit of a broader question, but I hope this is the right place to ask.
I think I need to provide a bit of backstory regarding my goals. We tried several different PM solutions (Wrike - interface was somewhat lacking, Redbooth - good UI but not really good for managing software). Jira seems like the next best choice - so we can keep track of releases and different types of software that produced (integrations with Github etc. seem particularly useful).
Is there a comprehensive guide that would explain how to use Jira - both conceptually (most important) and practically. I found some courses on Jira but they all mix intro heavily with Agile, which would be too much to consume (introducing both Agile and new PM suite at once).
