# How-To Guides

> Guides for tailoring the Aletyx Decision Control Tower Sidecar starter — customize its workflows and actions while the Tower contract stays fixed.

Guides for tailoring the Aletyx Decision Control Tower Sidecar starter. The Sidecar has no end-user interface — you customize its **workflows and actions** and configure behavior through environment variables, then verify the result in Tower and the target systems. Throughout, the **Tower integration and request/response contracts stay fixed** (see [Architecture](/docs/decision-control-tower-sidecar/architecture#core-vs-customizable)).

* [Customize the Promotion Workflow](/docs/decision-control-tower-sidecar/how-to/customize-workflow) — adapt the approval policy: review stages, assignment, branching, and which actions run.
* [Git Model Versioning](/docs/decision-control-tower-sidecar/how-to/git-model-versioning) — the Git example action: commit the promoted model's files to a repository on approval.

More example actions (messaging, REST callouts) follow the same enable-and-verify pattern; see [Configuration](/docs/decision-control-tower-sidecar/deployment/configuration) for the full variable reference.
