Thanks for the feedback, I'll look into the language packs issue and get back to you.
About the nvm version, it is mentioned twice in the new document: in Requirements and in Troubleshooting. If you mean that the exact version is not mentioned, that's a conscious decision. Given that the version can change in the future, it is better not to mention it explicitly so that the document stays up to date. You should be able to configure the correct version by running nvm install, or looking at engines within package.json if you're not using nvm.
