Changes to close the Issue #12

[kainszs]

Hello Moritz,

Thank you very much for your contribution. Would you please remove "For quick navigation throughout the documentation, please use the Table of Contents." before I merge the branches?

Further notes:

• The font Table of contents under text above have the same font size
• For the DUM the information in Supported building blocks is missing.
• Would you please change in the parameter section:

  "-m | None | An internal json file is used" to "-m | if None | An internal json file is used"?

This does not have to happen immediately. Good luck with your exam tomorrow!
