It's great not having to use sudo to install anything. :)

Let me know if it's reasonable or let me know what a better form might be, and I can have a go at refining it.

If you add this tip, please include a note that it will break nvm (nvm-sh/nvm#606)

Yeah, this is a bit more advanced than we're trying to target, and will break a lot of default setups.

It's a good idea, but I think it requires more subtlety than these tips will provide.
