Maybe add node version somewhere at first install?

Not really an issue but more of a suggestion... Maybe it would be a good idea to write somewhere the node version used when installing a theme? So if we come back to that theme one year later, we know which version to choose with NVM... I see a lot of issue coming from npm version, it would at least remove those one ;)
Just an idea, what do you think?

.nvmrc exists for this reason. You add a .nvmrc file with a node version to the root of a project and it will switch to that version when you enter the project directory through the terminal. Documenting the use of NVM and how to setup the .nvmrc file is what I would suggest.
