+## Using your own contracts
+
+If you want to use your own contracts there are a few simple steps. 
+
+1. Replace the `TipActionModule.sol` contract in `/packages/hardhat/contracts` with your own. 
+2. Update the script(s) in `/packages/hardhat/deploy` to deploy your contract(s) instead of the mock contracts.
+3. Change the tag in the `deploy:mumbai` script in `/packages/hardhat/package.json` to the tag(s) of your contract(s).
+4. (Optional) Remove the `/packages/hardhat/contracts/helpers` directory and related deploy scripts unless you want to use the `MockModuleRegistry` and `TestToken` contracts for testing and debugging.
