 # Sample AWS Blockchain Node Runner app for Scroll Nodes
 
-This is RPC Scroll nodes (L2Geth) setup on AWS guide.
+[Scroll](https://docs.scroll.io/en/getting-started/overview/) is a "Layer 2" scaling solution for Ethereum leveraging zero knowledge proofs. This blueprint helps to deploy Scroll nodes (L2Geth) on AWS as RPC nodes and use [Amazon Managed Blockchain Access Ethereum](https://docs.aws.amazon.com/managed-blockchain/latest/ethereum-dev/ethereum-concepts.html) node for "Layer 1". It is meant to be used for development, testing or Proof of Concept purposes.
