pnpm: What is purpose of `node_modules` in .pnpm?

Question

I've been thinking about migration from npm to pnpm.

Before starting to migrate, I first saw documentation(pnpm motivation).

There are hard link packages that point .pnpm store(Centralized) in .pnpm, and within node_modules, they point each package using symbolic links.

I removed node_modules in my project, then, I reinstalled packages using pnpm. Everything seemed as I expected, except there was a node_modules in .pnpm.

What's the purpose of the node_modules in .pnpm?

What packages are there?
