Hi @Potherca,
in Readme.md we are using long descriptive argument names, but the correct argument names are shorter.
Should we use the short names in readme too (technology..techn, description..descr)?
e.g.

Container(alias, label, technology, ?description, ?sprite, ?tags, $link)
Container($alias, $label, $techn, $descr="", $sprite="", $tags="", $link="")

@kirchsth That would lead to more changes than I currently have the mental bandwidth / feel comfortable with making.

It is welcome as a separate issue/MR.

@Potherca: OK I will fix it in one of my following changes.
