Until the content is finalized the plan is to keep it in MD format.
For medium terms it is something which needs to be reconsidered
as markdown as the source format for documentation has too many limits.
Happy for suggestions here.
In the meantime here's what needs to be done:
* finalizing (see comments)
* proofreading 1: accuracy, logic, more content related
* proofreading 2: grammar, spelling
* more? pls let me know
