# View a pipeline version

Open a version to check what a pipeline will do before you run it. You need read permission on the
pipeline service.

1. In **Manage Pipelines**, select the pipeline, then the **Pipeline Versions** tab.
2. Select the version's name to open its **Graph** and **Yaml** tabs.

- **Graph** is the layout of the steps, and it stays the same while a run progresses. Select a step
  to see its input and output parameters, arguments, command, image, and volume mounts, and any
  condition it runs under.
- **Yaml** is the file as uploaded, shown read only.

To start a run of this version, go back to **Pipeline Versions** and select the icon in its **Create
Run** column.
