 The above would make `pnpm.fetchDeps` call only install dependencies for the `@astrojs/language-server` workspace package.
 Note that you do not need to set `sourceRoot` to make this work.
 
+If you need to install packages for multiple workspaces, pass a list of workspaces to `pnpmWorkspaces`:

+```nix
+pnpmWorkspaces = ["@atproto/pds" "@atproto/did"]
