Each guide takes you through one job with udpstp, from the first command to a working result. If you haven't run a Test yet, start with the [quickstart](../getting-started.md).

[Understanding the results](../understanding-results.md) explains every line and warning of a result, and [Troubleshooting](../troubleshooting.md) has the fix for each message. The [security model](../security.md) explains the defaults, and [Stable interfaces](../reference/interfaces.md) says what scripts can rely on.
