 ```yaml
-- uses: local-ch/calculate-deployment-name-action@v1
+- uses: local-ch/calculate-deployment-name-action@v2
+  id: calculate-deployment-name
   with:
     app: ${{github.event.repository.name}}
     branch: ${{ github.head_ref }}
 ```

+This action export `DEPLOYMENT_NAME` as variable, and could be used anywhere as any other variable with `$DEPLOYMENT_NAME`
+Because we have cases like `customer-apps` where we have multiple apps needed to be deployed and their deployment name has to be calculated in same job, there is option to use output of step where you calculate deployment name.
+
+Example: `${{steps.step_id.outputs.name}}`, or if you had action defined like in top example, then you type `${{steps.calculate-deployment-name.outputs.name}}`, because step_id is `calculate-deployment-name`
