 #### Actions

-  - [evaluate-scenario](../.github/actions/evaluate-scenario/)
+We provide two [GitHub actions](../.github/actions/) for CARLOS:
   - [generate-job-matrix](../.github/actions/generate-job-matrix/)
+  - [evaluate-scenario](../.github/actions/evaluate-scenario/)
+
+They can be used within a GitHub CI workflow to aggregate a job list of simulation runs, and consecutively run all simulations.
 
 #### Workflow
 
-- analog to the local evaluation script, we provide a GitHub workflow
+The workflow combines the different actions and performs simulation evaluation  analog to the local `evaluation-scenarios.sh` script:
