+## Simulate a CI/CD pipeline
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/337282) in GitLab 15.3 [with a flag](../../administration/feature_flags.md) named `simulate_pipeline`. Disabled by default.
+
+FLAG:
+On self-managed GitLab, by default this feature is not available. To make it available,
+ask an administrator to [enable the feature flag](../../administration/feature_flags.md) named `simulate_pipeline`.
+The feature is not ready for production use. When this feature is enabled, it replaces the **Lint** tab.
+
+To look for pipeline syntax and logic issues, you can simulate the creation of a
+GitLab CI/CD pipeline in the **Validate** tab. A pipeline simulation can help find
+problems such as incorrect `rules` and `needs` job dependencies, and is similar to
+simulations in the [CI Lint tool](../lint.md#simulate-a-pipeline).
