The easiest way to get started with MUD is to use a template.
Ensure you have
Create and start the application:
pnpm create mud@next my-project && cd my-project && pnpm dev
Select the template to use.
Browse to the application. Usually it is at http://localhost:3000 (opens in a new tab), but if that port is in use it might be 3001, 3002, etc.
