I watched a video on Linux Setup for Competitive Programming (with Geany) by Errichto and wanted the same on my Windows laptop. If you're a beginner and want to use Geany as the default editor, follow the video linked above.

I did Geany setup as showed in Video, However, I wasn't able to Add/Edit template files using File Explorer. So, I worked around for a solution using PowerShell and made a short guide on it.

Do check out if you're a beginner like me : Geany Template Add/Edit Windows10

P.S. I made a guide on GitHub because markdown was easier for me to write and GIFs are added with each step.
