So, I just had a bit of a panic after I pressed Alt+R in Atom because I was getting an error message saying -Unable to find command: ruby-, telling me my PATH wasn't configured correctly. If anyone else on Windows 10 is having this problem, I found a way to fix it pretty easy.
1. In Files Explorer, right-click -This PC- in the navigation tree panel on the left.
2. From this menu, select -Properties- at the bottom
3. Select -Advanced System Settings-
4. Click -Environment Variables...- in the advanced tab
5. Under -System Variables-, highlight -Path- and click the -edit- button below.
6. You'll want to create a new variable by selecting -New-
In the blank highlighted row, you have to enter the location you have Ruby installed. I used the default location that the installer had selected, and if you did too, you should be able to select -Browse...- and navigate to C:\Ruby31-x64 or whatever version of Ruby you have installed. Highlight this Ruby folder, click -OK-, and make sure to restart Atom so it'll recognize your changes. Then FINALLY, everything worked for me ;_;
I wrote this for my fellow smooth brains who aren't great with computers yet, so I'm sorry if any of this seemed obvious, but I hope it helps anyone having the same problem. Google saved my life, thankfully!

I installed Ruby exactly as you said and also the IDE instructions plus the package installation instructions for atom-runner afterwards created the ruby file destination .rb then added in the text field print -something- and then pressed alt +r (for windows). what I got in return held me back from going forward with your video. This is the response I got after trying to run atom-runner. Unable to find command: ruby Are you sure PATH is configured correctly?

-2:45:35 There is no such thing as a -hashtag symbol-. A -hashtag- is a combination of a pound sign or number sign (in some English speaking countries it is called a HASH symbol, not hashTAG symbol) and a word or phrase, and ONLY when used with an app/program/service that supports using that combination as a method of tagging an item for searching.

At 59:50, my name.chomp() doesn't work. I get the following error:-
-userinput.rb:3:in -': undefined method -chomp' for nil:NilClass (NoMethodError)-
Any fixes?
Edit:-
If anyone is getting this error, add the '.chomp()' inside the puts statement. It'll be like this:-
puts(-Your name is - + name.to_s.chomp() + -, you are cool!-)

I just picked a random programming language on vs code so here I am
Edit: On vs code open the terminal in the program as a workspace thingy and you can interact with it

Does this old tutorial still makes sense in 2022? I ask this in the nicest possible way. Either way, thank you for sharing the video. I will watch it.

I like it when it's supposed that Linux user by definition is smart enough to install any software so you don't need to make instructions for Linux
