 ## Integration Testing
 
 Most tests require a running substrate node to communicate with. This is done by spawning an instance of the
-substrate node per test. It requires an executable binary `substrate` at [`v3.0.0`](https://github.com/paritytech/substrate/releases/tag/v3.0.0) on your path.

-This can be done by downloading the prebuilt binary:
