+
+To run this example, which uses the Foundry tooling, we first need to fork the [Sepolia network](https://sepolia.etherscan.io/). 
+
+In a terminal window do
+
+```
+export ETH_RPC_URL='https://your-sepolia-rpc-server/etc'
+yarn chainsep
+```
+
+In a second terminal window do
+
+```
+export DEPLOYER_PRIVATE_KEY="0xdeadbeefcafebabe"
+cd packages/foundry
+cp .env.example .env
+yarn deploy
+```
+
+when this completes, you should be see a contract address in the output:
+
+```
+...
+##### sepolia
+✅  [Success]Hash: 0xda5b4871929d1414a5b447769f4d8d757b1aea8e280555adb9dd7ec67bb6b683
+Contract Address: 0xA2B4473120b9d18abfE90EEb2722A57CB72C4212
+```
+
+Now, you can verify that you can read with the Foundry `cast` command:
+
+```
+🦄 cast call 0xA2B4473120b9d18abfE90EEb2722A57CB72C4212 'read()(uint)'
+3319415000000000000000 [3.319e21]
+```
+
+Note that because this is a fork of the Sepolia network, you should be getting a pretty up-to-date value for `ETH/USD`.
