I used YouTube tutorial to learn a few basic openings. GothamChess has a bunch of videos on different openings, where he goes through the main moves as well as a few variations. He’s definitely not for everyone though - he’s very much primarily a YouTuber/streamer and a chess teacher secondarily.
I used to work at an accounting/consulting firm who were dead set on writing business applications in VBA within Excel. The code was embedded in the notebook, and to distribute the software was sending the latest version of the Excel file. This made version control virtually impossible, and we would instead combine our work manually.
I cannot recommend having tech-illiterate people lead software projects.
