 Argo is implemented as a Kubernetes CRD (Custom Resource Definition). As a result, Argo workflows can be managed using kubectl and natively integrates with other Kubernetes services such as volumes, secrets, and RBAC. The new Argo software is lightweight and installs in under a minute but provides complete workflow features including parameter substitution, artifacts, fixtures, loops and recursive workflows.

 ## Continuous integration example
 Continuous integration is a popular application for workflows. Currently, Argo does not provide event triggers for automatically kicking off your CI jobs, but we plan to do so in the near future. Until then, you can easily write a cron job that checks for new commits and kicks off the needed workflow, or use your existing Jenkins server to kick off the workflow.
