I used to work as a Windows application developer for a while and even though Windows itself never gave me the feeling of “oh, I’d really like to have this at home too” there was the C++ debugger in Microsoft Visual Studio that I remember as being remarkably good, to this day I haven’t seen anything quite like it anywhere else.

Simon Tatham wrote this several decades ago, but I still think it’s all excellent advice:

Even if you’re not technical, it should be possible for you to learn how to write a good bug report if you’re interested and as a longtime developer I can tell you from experience that a really good bug report is a real delight to receive.

Documentation is always needed. If you have any aptitude at all for explaining things to people, it’s almost certain that you’d be able to help there.

If you don’t know where to start, I can recommend starting with making a tutorial for doing whatever it was that you yourself last found difficult to learn how to do.

You’re wrong.
