+# 3-Minute Cross-Chain dApp
+
+This QuickStart guide will run through how to start an Omni cross chain dApp in less than three minutes.
+
+In this guide you will:
+
+- Install the Omni CLI, scaffold a new project and run a local devnet
+- Deploy contracts using foundry to the local devnet and test their functionality
+
+## Steps
+
+### Step 1: Install the Omni CLI
+
+First, install the Omni CLI by running the following command:
+
+```bash
+curl -sSfL https://raw.githubusercontent.com/omni-network/omni/main/scripts/install_omni_cli.sh | sh -s
+```
+
+You may otherwise install from source by following the steps shown in the [Omni CLI Tools section](../../tools/cli/cli.md).
+
+### Step 2: Scaffold a new project
+
+Next, create a new directory for your project and scaffold a new project using the Omni CLI:
+
+```bash
+mkdir my-omni-dapp
+cd my-omni-dapp
+omni developer new
+```
+
+Note: this requires [foundry](https://github.com/foundry-rs/foundry) to be installed on your machine.
+
+<details>
+<summary>Test the Contracts with Forge</summary>
+
+You can test the contracts with Forge by running the following command:
+
+```bash
+forge test
+```
+
+</details>
+
+### Step 3: Run a local devnet
+
+Start a local devnet by running the following command:
+
+```bash
+omni devnet start
+```
+
+Note: this requires [Docker](https://docs.docker.com/get-docker/) to be installed on your machine.
+
+### Step 4: Deploy contract
+
+Deploy the contracts to the local devnet using foundry:
+
+<details>
+<summary>Obtaining Parameter Values</summary>
+
+You can obtain RPC URL values and portal addresses for the running devnet chains by running the following command:
+
+```bash
+omni devnet info
+```
+
+And you the private key value is the first anvil private key, found by running:
+
+```bash
+anvil
+```
+
+</details>
+
+```bash
+forge script DeployXGreeter --broadcast --rpc-url http://localhost:8000 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
+forge script DeployXGreeter --broadcast --rpc-url http://localhost:8001 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
+forge script DeployXGreeter --broadcast --rpc-url http://localhost:8002 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
+```
+
+### Step 5: Perform an XGreet
+
+You can now perform an XGreet by running the following command:
+
+<details>
+<summary>Obtaining Deployment Addresses</summary>
+
+You can obtain the XGreeter deployment addresses from the output of the previous forge script deployment.
+
+Because the devnet has just been started, the addresses will be the same as the ones shown below:
+
+```bash
+omni_evm: 0x0DCd1Bf9A1b36cE34237eEaFef220932846BCD82
+mock_op: 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853
+mock_arb: 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853
+```
+
+</details>
+
+```bash
+cast send 0x0DCd1Bf9A1b36cE34237eEaFef220932846BCD82 'xgreet(uint64,address,string)' 1655 0xa513E6E4b8f2a923D98304ec87F64353C4D5C853 '3 minutes go by too fast!' --value 0.1ether --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 --rpc-url http://localhost:8000
+```
+
+### 🎉 Done 🎉
+
+You have successfully deployed and interacted with an Omni cross-chain dApp in less than three minutes!
