 15. optional: in addition to the Vercel project based on the `apps/backend` folder, create a second project based on the `apps/frontend` folder. No environment variables needed.
-16. optional: if your Vercel deployments fail but after a redeployment without build cache they work, add an environment variable [`VERCEL_FORCE_NO_BUILD_CACHE`](https://vercel.com/docs/deployments/troubleshoot-a-build#managing-build-cache) with value `1` to force Vercel to not use the build cache.
