5. Customize Your XBlockΒΆ

Now that you have created your XBlock skeleton, myxblock, you need to make it do something. This part of the tutorial explains modifying myxblock; for practical purposes, we will update it to match the Thumbs XBlock that is installed with the XBlock SDK.

For more information about the Thumbs XBlock, see Anatomy of an XBlock

For more information about the different components of an XBlock, see XBlock Concepts.
