Question: I was unable to find resources to understand how Docker Hub images can be managed.

I have an image tagged with V0.0.1 and built a new one tagged V0.0.2. Now I want to remove the V0.0.1 image as the new version is built differently and I don't want users to pull the old image.

Answer: 
You can easily remove or delete a tag with an image from Docker hub.

1. Log in to Docker Hub.
2. Go to "[Repositories](https://hub.docker.com/repositories)" on the top navigation bar, then open a specific image.
3. Click the "Manage Repository" button.
4. Go to the "Tags" tab on the top of the page.
5. Mark the tag which you are going to remove with a checkbox.
6. You will see an "Action" drop-down box on the top left. Click it and select "Delete".

That's it.
As of October 2016, delete button/icon is available when you click on your Docker Hub repository and Tags tab, on the right hand side of each version.
