Condition parameters
When adding this Condition you will be presented with a list of Condition Templates you created earlier. Choose one to add it to your Workflow.
Creating Condition Templates is very simple, yet effective and can get very powerful with multiple nested Conditions and different logical operators between them.
The process is practically identical to adding regular Conditions offered by JIRA, so if you're familiar with JIRA workflows it should be an easy task, however you can learn more about Condition Templates here.
