+    If you are using an Apple Silicon Mac or another ARM64 device then use this command.
+
+    ```bash
+    $ docker run -dp 3000:3000 \
+        -w /app -v "$(pwd):/app" \
+        node:12-alpine \

+    ```

     - `-dp 3000:3000` - same as before. Run in detached (background) mode and create a port mapping
     - `-w /app` - sets the "working directory" or the current directory that the command will run from
     - `-v "$(pwd):/app"` - bind mount the current directory from the host in the container into the `/app` directory
