I will not add the usage, because the usage chapter will be created in PR #45. We should merge this first, if its fine for you. I changed the structure of the docs a bit but mainly added content. Nothing fundamental. Proofing would be good, though.

The verbosity is very adequate and I don't see any mistakes. Thanks. (Still, you might consider adding a sentence about the limitations of the profiles.)

[p-snft]

As far as I understand, the profiles include space heating (SH) and domestic hot water (DHW). Thus, they become inaccurate if the insulation is different from the one originally assumed: Demand in summer is dominated by DHW, demand in summer may or may not be dominated by SH - depending on the insulation. (This is also the way, I interpret #20.)

Maybe, this limitation should be made explicit.

I just revised the general structure and added some information about electrical load profiles. I did not touch the content of the heat profiles.

I added an issue for further ToDo's #48.
