-LayerZero is an innovative open-source, immutable messaging protocol, that connects blockchains (50+ and counting) to enable omnichain interoperability for blockchain applications. With LayerZero V2, developers have the power to create applications that can seamlessly interact across multiple blockchains.

 All of the contracts in `/oapp` can be referred to when building an Omnichain Application (OApp):
 
-- **OApp**: The OApp Standard provides developers with a generic message passing interface to send and receive arbitrary pieces of data between contracts existing on different blockchain networks. See the[ OApp Quickstart](https://docs.layerzero.network/contracts/oapp) to start building.

-The core, immutable protocol contracts (i.e., the [LayerZero Endpoint](https://docs.layerzero.network/explore/layerzero-endpoint)) live in `/protocol`.

 ## MessageLib
 
-The contracts related to the append-only, on-chain [MessageLibs](https://docs.layerzero.network/explore/messagelib) live in `/messagelib`. Inside you can see reference implementations for how the [DVN](https://docs.layerzero.network/explore/decentralized-verifier-networks) and [Executor](https://docs.layerzero.network/explore/executors) communicate with the Ultra Light Nodes on each chain.
