+
+- Git initialisiert
+- GitLab als `remote` eingerichtet
+
+## Vorgehen
+
+1. [CI/CD Settings](./-/settings/ci_cd)
+   - Timeout
+     - [projektseitig](./-/settings/ci_cd#js-general-pipeline-settings)
+     - serverseitig (Admin informieren)
+   - [Runners Settings](./-/settings/ci_cd#js-runners-settings)
+     - Server-Admin: Freigabe der GPU
+   - [Variables Settings](./-/settings/ci_cd#js-cicd-variables-settings)
+2. `.gitlab-ci.yml` erstellen
+    ```yaml
+    create-file:
+      stage: build
+      image: python
+      tags:
+        - gpu
+      script:
+        - |
+          cat <<EOF > test.py
+          with open('output.txt', 'w') as f:
+            f.write('hello world!\\n')
+          EOF
+        - python test.py
+      artifacts:
+        paths:
+          - output.txt
+
+    test-file-output:
+      stage: test
+      script:
+        - grep -q "hello world!" output.txt
+      dependencies:
+        - create-file
+
+    deploy-output:
+      stage: deploy
+      script:
+        - cp output.txt release.txt
+      artifacts:
+        paths:
+          - release.txt
+      dependencies:
+        - create-file
+    ```
+3. `$ git add <files>`
+4. `$ git push`
+5. [Pipelines](./-/pipelines) beobachten
+   - ![pipeline_badge](./badges/main/pipeline.svg)
+6. [Artifacts](./-/artifacts) abrufen
