 This Action will automatically tag each image as follows:
 
-    {Image_Name}:{shortSHA}
+    {Image_Name}:{IMAGE_TAG}
 
 Where:
 - `Image_Name` is provided by the user as an input.
-- `shortSHA` is the first 12 characters of the GitHub SHA that triggered the action.
+- `IMAGE_TAG` is either the first 12 characters of the GitHub commit SHA or the value of INPUT_IMAGE_TAG env variable
+
+Additionally it will use Git Tags pointing to the HEAD commit to create docker tags accordingly. 
+E.g. Git Tag v1.1 will result in an additional docker tag v1.1.

+3. `DOCKERHUB_REPOSITORY`: if value is set, you don't need to set `IMAGE_NAME`. It will push the image to the given dockerhub repository instead of using GPR.
+Why? Because Github Actions don't support downloading images without authentication at the moment. See: https://github.community/t5/GitHub-Actions/docker-pull-from-public-GitHub-Package-Registry-fail-with-quot/m-p/32782
