How to setup a simple proxy with auth command? Need step-by-step guidance!

Hey everyone!

I’m trying to setup simple proxy with auth command for a small project, but I’m kinda stuck. I’ve looked around but most guides are either too complex or outdated.

Can someone break it down for me step-by-step? Like, what tools to use, how to configure it, and how to add the auth part? I’m not super techy, so plain English would be awesome lol.

Also, if there’s a way to test if it’s working properly, that’d be great.

Thanks in advance! You guys are lifesavers.
