YII2 How to play RBAC?

This thing looked for a long, still did not understand.

I remember the first time I approached RBAC, the framework was

1, create the role;
2, specify which methods the role can access;
3. Then assign a role to the user ...

But YII2 I did not find the second step how to do, seemingly only with code to write the verification of the role of the character, then the question came: how to play this goods in the end?
