+To try it out, start by deploying a contract by choosing an account to submit from, picking a home key with the first twenty bytes set to that account address, and calling `deploy` with the key and your contract’s creation code (including ABI-encoded constructor arguments, of course). Alternately, you can call `lock` to give control to HomeWork and mint an NFT, and `redeem` or `redeemAndDeploy` to burn it and take control back.
+
+Two big caveats to be aware of:
+- `msg.sender` will refer to HomeWork, not to the submitter - you can still get at the submitter by calling into HomeWork *(easiest if you set a reverse lookup for the home address first)*, or you can just include it as a constructor arg.
+- you won’t be able to deploy any contract to a home address that already has a contract deployed. If you deploy a contract that can’t be removed via `SELFDESTRUCT`, HomeWork’s job is done and it will not be able to interact with that home address anymore. *(Well, state rent might change that...)*
+
 To run tests locally, start the testRPC, trigger the tests, run the linter, and tear down the testRPC *(you can do all of this at once via* `yarn all` *if you prefer)*:
 ```sh
 $ yarn start
