Jira Cloud - How to Install
NOTE: The Cloud apps will ONLY work in Jira on demand cloud.
You need to be a JIRA Administrator in order to install the app.
As a JIRA Administrator, navigate to the Administration page and click on "Apps" in the top menu bar.
Now select the "Find New Plugins" menu item and enter the name of the app you want to install, into the Search box on the left.
In the resulting search, select the app you want to install, and click on the "Buy Now" or "Free Trial" buttons. Clicking on one of them will take you to https://my.atlassian.com where you can either enter your userid/password or create a new account. The Buy Now button lets you buy a license whereas the Free Trail gives you a free 30-day evaluation version.
The software will now be installed and the license key will be automatically added to activate it.
