How do I restrict access to a post?
Let's assume you want members of the Premium group to be able to view some restricted posts.

If you want to create a new protected post, simply go to Posts > Add New as usual and in the Groups box input Premium in the Read field. Save or publish your post.
If you want to protect an existing post you can simply edit it, input Premium in the Read field of the Groups box and update the post.

In both cases, it doesn't matter if the Premium group already exists or not, if it doesn't, it will be created automatically.

If the Premium group already exists and you want to protect one or more existing posts in bulk, go to Posts, select all posts you want to protect and choose Edit in the Bulk Actions dropdown.
Now click Apply, select the Premium group and click Update.

After you publish or update your posts, only members of the Premium group will be able to see them.
I want Advanced and Premium members, where the Premium members can access everything that Advanced members can access. How can I do that?
Example: Advanced and Premium members

Go to Groups > Groups > New Group and add two new groups, let's call them Advanced and Premium - select Advanced as the Parent for the Premium group.
Now create an example post that only members of the Advanced group should be able to access and choose the Advanced group in the Read field of the Groups box.
Create another post for members of the Premium group and choose the Premium group for that post.
Assign test users to both groups, log in as each user in turn and see which posts will be accessible.

Go to Groups > Groups > New Group and add two new groups, let's call them Green Members and Red Members
Now create an example post that only members of the Green Members group should be able to see and choose the Green Members group in the Groups box.
Create another post for Red Members and choose the Red Members group for that post.
Assign a test user to each of the groups, log in as one of them and you will see that the member of the Green Members group will only have access to the post protected by that group but not to the post protected with the Red Members group and vice-versa.

Are access restrictions for Custom Post Types (CPT) supported?
Yes. Access restrictions can be turned on or off for specific CPTs on the Groups > Options page.
How can I show groups that users belong to on their profile page in the admin section?
Go to Groups > Options and enable the option under User profiles.
Developers ... aka ... What about Groups' API?
