 ## Prototype usage
 
-This is an extremely early prototype that demonstrates basic breadth-first concepts. It outlines the core engine flow using batched sets, and includes a basic scope-local promissory workflow. These patterns are being matured for real production use in [graphql-ruby](https://github.com/rmosolgo/graphql-ruby/pull/5509). To experiment with this prototype, you can setup a `GraphQL::BreadthExec::FieldResolver`:
