Yes, I will be providing documentation in addition to the starter project which will showcase how to use each of the blueprint nodes. Here is the in progress API reference. It still has a lot of missing content, but I will be updating it as I finalize the workings of each blueprint node.

When I release the first beta version I will also launch a Slack channel where you can ask me questions and get clarification on the workings of any of the blueprint nodes. We can also discuss strategies to integrate the system into your project.
