Documenting NVM first use

[SamErde]

On a new Windows machine with Node.js installed, I ran nvm use 16 (README permalink) and got the message:

node vv16.18.0 (64-bit) is not installed or cannot be found.

Should a "first time use" walkthrough include instructions to install Node.js and then run nvm install 16 or nvm install latest?

Hi good point.

I've tested this with versions 14-16, but likely higher version will work just fine. Probably the best option is to use the LTS version, which I think now is 16 https://github.com/nvm-sh/nvm#long-term-support

Great, I'll submit a PR for the readme with regard to this for Node.js newbies like me!
