 ### Importing data to firestore
 To achieve this goal we use [node-firestore-import-export library](https://www.npmjs.com/package/node-firestore-import-export).
 1. Create `docker-compose.override.yml` and add this content to it
-```
-version: '3'
 
-services: 
-  app:
-    volumes:
-      - ~/path/to/firebase/credentials.json:/var/www/credentials.json
-    environment: 
-      - GOOGLE_APPLICATION_CREDENTIALS=/var/www/cred.json
-```
+    ```
+    version: '3'
+
+    services: 
+      app:
+        volumes:
+          - /path/to/firebase/credentials.json:/var/www/credentials.json
+        environment: 
+          - GOOGLE_APPLICATION_CREDENTIALS=/var/www/cred.json
+    ```
+
 1. Run `docker-compose exec app firestore-import --yes --backupFile /var/www/vue/data/back-up.json`
