 # Welcome
 
+<<<<<<< HEAD
+**Welcome to the Zama Confidential Blockchain Protocol Docs.**\
+The docs aim to guide you to build confidential dApps on top of any L1 or L2 using Fully Homomorphic Encryption (FHE).
+
+## Where to go next
+=======
 Welcome to the Zama Protocol Documentation, your guide to building confidential applications on public blockchains using
 **Fully Homomorphic Encryption (FHE)**.
 
 Zama Protocol enables developers to write smart contracts that compute on encrypted data without ever decrypting it.
 This means sensitive user inputs, interactions, and outcomes can remain private onchain.
+>>>>>>> main
+
+If you're completely new to FHE or the Zama Protocol, we suggest first checking out the [Litepaper](https://app.gitbook.com/o/-MIF05xPVoj0l_wnOGB7/s/Edp93qMUwAKDm540ieDj/), which offers a thorough overview of the protocol.&#x20;
+
+Otherwise:
+
+🟨 Go to [**Quick Start**](https://app.gitbook.com/s/rDmRmmmSrBgV0SFO4eiZ/getting-started/quick-start-tutorial) to learn how to write your first confidential smart contract using FHEVM.
+
+🟨 Go to [**Solidity Guides**](https://app.gitbook.com/o/-MIF05xPVoj0l_wnOGB7/s/rDmRmmmSrBgV0SFO4eiZ/) to explore how encrypted types, operations, ACLs, and other core features work in practice.
+
+🟨 Go to [**Relayer SDK Guides**](https://app.gitbook.com/o/-MIF05xPVoj0l_wnOGB7/s/Xn2WDIaMPelG4OHaUISx/) to build a frontend that can encrypt, decrypt, and interact securely with the blockchain.
 
-## Where to go next?
+🟨 Go to [**FHE on Blockchain**](architecture/overview.md) to learn the architecture in depth and understand how encrypted computation flows through both on-chain and off-chain components.
 
-\[To Update]
+🟨 Go to [**Examples**](https://app.gitbook.com/o/-MIF05xPVoj0l_wnOGB7/s/UTmYJ1UQyasGNx2K8Aqd/) to find reference and inspiration from smart contract examples and and dApp examples.
