@markushausammann I added some additional info about this topic.
PS About reposting links in coderwall. Coderwall add special sign if post have only link - it means that they are support this kind of sharing information. :-)
But you are right - some additional info with links may be really helpfull - background for example (usecase of author).
@davidchase03 Thx for reply!:) I added a short background. Should it be more specific?
@frol Thanks! It was really simplier. :)
