+## Local Testnet
+
+To deploy the relay contract to a local environment for testing use our convenience script [here](./sdk/scripts/init-bridge.ts):
+
+```shell
+# start local ethereum testnet node
+docker-compose up anvil
+# run script to deploy the relay contract
+cd sdk
+yarn run deploy-relay --init-height 2016 --private-key dev-0 --dev --network testnet
+```
+
+The initialization height should be a multiple of 2016 with at least one subsequent retarget (i.e. if using 2016 as the starting height, blocks 4031-4032 must exist).
