+W celu utworzenia zasobów z wykorzystaniem skryptów zawartych w tym folderze należy:
+- posiadać zainstalowanego `Dockera`
+- zbudować obraz i uruchomić kontener 
+    ```bash
+    docker build -f ./Azure.Dockerfile -t azure-image .
+    docker run -it azure-image
+    ```
+- postępować zgodnie z instrukacjami wyświetlanymi w terminalu
+--------------------
+W celu usunięcia utworzonych zasobów uruchomić wcześniej stworzony kontener i wykonać w nim skrypt:
+
+```bash
+./clean.sh
+```
+###### ...lub wyklikać w portalu Azure
