So in the hope of triggering someone to give me the missing link (maybe even a hyperlink) for me to understand it, here is a the situation:
I'm a SW dev that also have done a lot of sysadmin work. Yes, I have managed to install it. And that is about it. There seems to be so many features there but I really really don't understand how I am supposed to use the product or the documentation for that matter.
I could start an import of Twitter or something else an it kind of shows up. Same with anything else: photos etc.
It clearly does something but it was impossible to understand what I am supposed to do next, both from the ui and also from the docs.
