 # Why Workflow?
 
-The Workflow Plugin was built with the community’s requirements for a flexible, extensible, and script-based pipeline in mind. The Workflow Plugin:
-* Supports complex processes: you can fork/join, loop, and parallel
-* More Resilient: survives master restarts
-* Is Pausable: waits for human input/approval
-* Provides Faster cycles: restarts from checkpoints
-* Is Visualized: provides status at-a-glance dashboards including trending
