-Please read on to learn [about Omni](./learn/introduction/introduction.md), [the network](./protocol/introduction/introduction.md), [developer docs](./develop/contracts.md) and [running a validator](./operate/introduction/introduction.md).
+Omni is an Ethereum-native interoperability protocol that establishes low latency communications between all Ethereum rollups. Omni offers a secure, performant, and globally compatible architecture that presents Ethereum as a single, unified operating system to both users and developers.
+
+[**Learn**](./learn/introduction/introduction.md): New to Omni or Ethereum interoperability? Start here to understand the basics of how Omni connects all Ethereum rollups.
+
+[**Protocol**](./protocol/introduction/introduction.md): Dive deep into Omni’s network architecture and core processes. This section is ideal for those interested in the technical underpinnings and innovative solutions Omni brings to Ethereum interoperability.
+
+[**Develop**](./develop/contracts.md): Ready to build on Omni? Explore our developer resources and examples to easily integrate Omni into your application. This area is tailored for developers seeking practical tools and examples to expand their applications to all Ethereum rollups.
+
+[**Operate**](./operate/introduction/introduction.md): Learn how to run an Omni validator and contribute security to Omni’s network.

 # Background
 
-Ethereum’s commitment to the rollup-centric roadmap has forced the network to scale via isolated execution environments. While this allows rollups to support various execution environments and programming languages, creates negative externalities that degrade Ethereum’s network effects. Specifically, liquidity, users, and developers are fragmented between disparate ecosystems. The expanding variety of rollup designs and their growing adoption will only exacerbate these issues. Consequently, Ethereum requires a native interoperability protocol that realigns the network with its original vision of being a single, unified operating system for decentralized applications.
