1. Open /admin/events/contracts (Events Contracts Templates) and click Add New.
2. Enter a Title and draw Your Signature on the signature pad (both required — you'll get "Empty Title" / "Empty Signature" otherwise), then Save.
3. You land in the contract page builder: click Add Module to add text blocks, a customer-details block, a totals block, spacers, etc.; edit each module, move modules up/down, and use Preview / the Live Preview toggle to see the result. Type @ tags such as @customerFirstName, @eventName, @total, @totalOwed, @contractSignatureDate in text blocks to merge live proposal data.
4. Settings lets you rename the contract and toggle Is Active? (uncheck this to retire a template without deleting it) and redraw your signature.

From the list page you can Clone a template to start a new one from it. In the current version there is no delete button in the admin UI for contract templates — use Is Active? to hide a template you no longer want offered; existing signed proposals keep their frozen copy of the contract regardless.
