DemoExampleMaker: documentation

[nbriz]

once we create a new place for the /docs && start migrating the stuff from the Wiki over there, we're gonna drastically need to update these docs to reflect all the new changes @Cthomp7 has worked on

[Cthomp7]

@nbriz Do you still need someone to update this documentation? I happy to do so if needed :)

[nbriz]

@Cthomp7 yes! most definitely, we've shared the tool with a few folks, but having some updated docs for this will make it way more accessible!
