Content is at the moment as follows:

- Marcom.md document is the contribution of Radium, as on pad 17 jan 8:20 with small typos corrected
- layout.md contains the contribution of Elena and Fredd and is a practical documents

my first merge of the docs is in MCL.md that therefore is the one to read to give compartments

the index of the doc has been worked up on pad https://pad.dyne.org/code/#/1/edit/1vtinoUpsmYruHjDHiW+Ng/CrTbI64coYYuDY72TIheqOkW/

Structures of folders has to be kept aligned with doc!
