+# Vertex Protocol
+
+This repository contains the smart contract implementations for the Vertex Protocol ecosystem.
+
+## Project Structure
+
+The repository is organized into two main projects:
+
+- **[vertex-contracts/core](./core)**: EVM implementation of Vertex core functionality
+- **[vertex-contracts/lba](./lba)**: Vertex LBA (Liquidity Bootstrap Auction) contracts
+
+## Requirements
+
+- Node.js >=16
+- [Yarn](https://yarnpkg.com/)
+
+## Getting Started
+
+Each project has its own setup and development commands. Navigate to the respective directories for project-specific instructions:
+
+```
+# For Vertex EVM Core Contracts
+cd vertex-contracts/core
+yarn install
+yarn compile
+
+# For Vertex LBA Contracts
+cd vertex-contracts/lba
+yarn install
+# Follow the .env setup instructions
+```
+
+## Available Commands
+
+### Core Contracts
+
+- `yarn compile`: Compile Vertex EVM contracts
+- See project-specific README for more details
+
+### LBA Contracts
+
+- `yarn lint`: Run prettier & SolHint
+- `yarn contracts:force-compile`: Compile contracts and generate TS bindings + ABIs
+- `yarn run-local-node`: Run a persistent local Hardhat node for testing
+- See project-specific README for more details
+
+## Further Documentation
+
+For more detailed information about each project, please refer to their respective README files.
