+This is a NextJS project bootstrapped with `create-next-app@latest` that contains a Tailwind
+email using most of the features we provide that will be auto-built on testing to
+make sure this new release works properly with the latest version of NextJS when being built.
+
+We do this testing so that things are more reliable and this couldn't be done using pnpm
+workspaces as they link code instead of actually copying the content into node_modules.
+The solution we use to copy the code in a way that mimics the actual `npm install @react-email/tailwind` is `yalc`.
+
+Se [the test file](../_tests/nextjs.spec.ts) for more info.
