How do you document your design process? I don’t mean organizing files and naming conventions but the actual design decisions that you’ve made while working on a project. When clients require new work on the websites/apps that I’ve been working on in the past, I need to study the project again to make better decisions for the updates. The same goes if a project comes along that is comparable to a project in a past. A time consuming search for notes, sketches and similar items follows. Do you have any best practices on how to approach that?please help.
Thanks.

I didn't find the right solution from the internet.
