Associate an optional Confluence page with each Jira issue
Create a Confluence page for an issue
In Jira projects linked to a Confluence space, each issue will have a "Confluence" tab that initially has a "create page" link. Clicking this will create a new Confluence page named after the issue key (e.g. MYPROJ-123).
View an issue's Confluence page in Jira
If the issue already has a page in Confluence (i.e. with the same title as its own key), this tab will display its contents.
View an issue's Confluence page in Confluence
Sometimes you will need to go to Confluence to properly view the issue page or to edit it.
