If it's the cloud hosted version (I can't speak to their on-prem software since I haven't used it in a few years), watch out for the nonsense that is having two separate markup languages, used it two different contexts. The original "Atlassian markup" (made famous by Confluence) is used, as best I can tell, in issue creation and descriptions, whereas some kind of Markdown hybrid is used in issue comments Be careful if you use subtasks for issues, which may sound like a perfectly reasonable work breakdown idea but subtasks are snowflakes in Jira and become very hard to have visibility into, assign points to, etc The rest of the rant I'll omit, since it's more rooted in my personal hatred for their products and has less substantiation
