There has been some suggestion on how to style the code, do inline documentation or have code auto-styled.
To ensure that we don’t lose this information in the vast amount of post here and on GitHub, this living topic is created what shall collect and describe nicely all aspects to this regard.
For the time being anyone is welcome to edit this wiki.
If you feel that there is something that should be mentioned here, just reply in this topic and quote (discourse allows to quote across different topic) or reference to it, we will take from there.
