This page will guide you through the steps for adding a new connection.
Having authorized your JIRA instance with your Salesforce.com account by adding an application link, you may now add a new connection, which actually connects your JIRA instance to your Salesforce.com account.
In the Add new Cloud/System Connection section underneath the connections list, type in a name for your new connection. Select "Salesforce.com" as the External System Type. Click Add.
The next screen is titled Add New Connection. Here you will need to select an application link for the connection. Choose your desired application link from the drop-down menu. In the following example screen, we are using the "Salesforce" application link (which we created previously). Click Add.
Or, if you want to add a remote system reference, the next step you are required to do is to create mappings and mappings schemes for the connection you just created.
