+# Adding a new dashboard to AWS
+
+## Preparing files
+ - Define the whole dashboard script as a function named run_dashboard(token, container_ip). It is called in the main file app.py later.
+ - Add files verification.py, setup_callbacks.py, environment.yml and the dashboard source file (dashboard.py) to the same directory app.py is located.
+
+## Building and publishing the image to repository
+ - Inside terminal, run:
+    * docker build -t <tag_name> .
+ - Using Docker Hub to store the image:
+    * docker login
+    * docker tag mypanelapp:latest myuser/mypanel:latest
+    * docker tag push myuser/mypanel:latest
+
+ - In case of using public AWS ECR, the user needs to be logged in before pushing any images.
+    * aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/a3o6k3z1
+    * When using WSL 2, "Error saving credentials" may occur. To fix this, ~/.docker/config.json needs to be modified so that "credsStore": "".
+    * docker tag <tag_name> public.ecr.aws/a3o6k3z1/atlas:<tag_name>
+    * docker push public.ecr.aws/a3o6k3z1/atlas:<tag_name>
