OAuth authentication (Cloud and Server/Data Center)
This section is a bit out of date and needs changing:

• Images use a very old version of Jira (see the logo)
• Directions on how to find Application Links in Jira is not correct for Jira Cloud (though it is correct for Jira DC/Server). Refer to:
  https://support.atlassian.com/jira-cloud-administration/docs/use-applinks-to-link-to-atlassian-products/
  and perhaps advise to go direct to:
  https://<jira-server-url>/plugins/servlet/applinks/listApplicationLinks for Jira Cloud

• Step 7 "Select the Use this URL check box, and then click Continue." doesn't exist any more
• Step 8 - explicitly state no other field needs to be completed
• Step 15 - explicitly state that Jira MUST be logged in as the service administrator account before Click Request Jira for access.
