How do you write a documentation for a new project?

Question

I have this idea to create a learning webapp for high schoolers.
Something like solo learn as an idea but far away from it's function.
I want mine to be more like moodle yet very simple to use.
Hence a virtual classroom.

Is it possible to have this documented before starting the project or after the project is completed.
Thanks.

Answer 1

Documentation usually comes after the project is complete.

If you want for something to show how this web app will function and it's components/dependencies, you could make UML diagrams (Deployment, Activity etc.).

Answer 2

Oh you want it for the users, well yeah, no problem to write something like a presentation of what this app will do.

When I read documentation, I thought of a user manual.

Answer 3

Ohkay, but will users understand this UML diagram the way you and I do? I mean wouldn't it be easy to just write something in text to explain how the software or project in question works?
