I like drawings to explain stuff. It’s probably the most straightforward way to document things. But the pain of traditional drawings is the inability to track changes to them. It’s easy to track changes to text or code by tracking them in a git. It’s not easy when it’s a binary blob which is what most images are. SVG format helps a lot. I use it as much as possible, but it’s still very verbose, and I think not easy to see the diff and understand what happened over time.
I do quite a bit of work on the go; most of it happens on the phone. It’s not easy to software development on the phone. That is mostly due to the small screen size and lack of a hardware keyboard. Nevertheless, I have made numerous small changes to code on the phone, deployed them. The other big use case is browsing the code on the go, doing reviews and accepting merge requests, etc. I use the following apps for the same.
I use git all the time. I use quite a few GUI tools to work with git. But I also have some more CLI tools to help me work with git.
