Make sure ports 5555 and 5173 are free.
Install Docker on your machine with compose and cd into the project dir and run docker-compose up or docker compose up depending on your docker + compose installation.
Now open your web browser and go to url http://localhost:5555 (prisma studio). Here open the Roles model and add the roles USER and ADMIN.
Now you can open http://localhost:5173 (svelte app) and make your user account and assign it ADMIN role from prisma studio.
Congrats! Setup is complete, happy developing!
