In your Project, Jira members can access the Settings page by clicking on the Settings link if you don't have any stand-up linked yet or the Configuration button at the top of your daily report if you already have.
Click on 'Add new connection' button to display channels with StandBot installed. You can link different stand-ups with the same project.
Then, you simply have to select the Jira project and Slack channel with StandBot installed.
Click on the Save button to applied changes and you're ready to go. From now on, every time StandBot asks team members for status they can add Jira issues they've worked on or would be working on.
