Following the notes on how to <a target="_blank" href="https://zeropivot.xyz/notes-on-setting-up-the-windows-subsystem-for-linux-on-windows-10-pro-wsl2">install Ruby 3.0.0 on Windows 10 / WSL2 Ubuntu</a> ...
If you want to have something resembling intellisense in your Ruby code in Windows 10 and VScode:
In a powershell/cmd terminal assuming you have Ruby 3.0.0 installed:
<code>gem install nokogiri --platform=ruby</code>
That may take a while...
Then, when that is finished:
<code>gem install solargraph</code> (It installs solargraph AND rubocop)
<hr />
For the linter, in VScode you can open a powershell terminal in the same directory you are working in and type <code>rubocop -A</code>, to auto-lint everything you are currently working on. 
Do that everytime you want a cleanup to your code; auto-linters currently do not work well in VScode (at least for me), and also has an extreme performance penalty, the more files you have.
In VScode, install the <a target="_blank" href="https://marketplace.visualstudio.com/items?itemName=castwide.solargraph">Solargraph extension</a>
Restarting your terminal and/or VScode, you should have something resembling intellisense when you hit <code>CTRL + SPACE</code> or as you type. If you highlight, say, <code>Array.new</code>--it will show you info on said data structure.

Notes on a Ruby 3.0 Development Environment for VScode (linter/intellisense) on Windows 10

Formally trained as a Computer Scientist; ruby is my language of choice and I am beginning game development in DragonRuby -- I am also an Artist and plan to incorporate my art assets with code.
