Whether you have a specific need to solve or want to explore the wider possibilities of JSU, our use cases will help get you started. We have included examples of our more common use cases for you with scenarios and step-by-step instructions. You can use JSU to create simple automation rules or build more intricate combinations to bring more powerful functionality to your Jira projects. Why not try some out in a test instance?

If you want to create validation and conditional rules, try rule builders for [Conditions](https://appfire.atlassian.net/wiki/spaces/JSUCLOUD/pages/1958084925) or [Validators](https://appfire.atlassian.net/wiki/spaces/JSUCLOUD/pages/1973288961). 

If you aren’t familiar with editing workflows, see our [Jira Workflow Fundamentals](https://appfire.atlassian.net/wiki/spaces/JSUCLOUD/pages/12518207) topics or visit Atlassian’s [documentation](https://support.atlassian.com/jira-cloud-administration/docs/work-with-issue-workflows/) for Jira Cloud Administrators. We recommend testing your rules in a test environment before publishing changes to live projects. 

> ✅ To help ensure that your JSU rules work the way your team expects, test your workflows in a test project with user permissions that represent the different roles within your team.
