Since the tutorial section doesn't have a place for the Penumbra expansion yet, I'm just going to post my guides in here ^^

There are two, the first one talks about the basics of hacking and cloaking while the second one is about Umbral Choir exclusive stuff. Note that I forgot to mention linking systems to Umbral Choir's home system but aside from that the guide should have everything in it, including my recommendations regarding their playstyle.

Nice, Pengolin - I'll be watching these through tonight.

@PangolinAdvisor Many many thanks for making these detailed Penumbra and UC guides, really helpful. I can finally make some sense out of Penumbra and UC. 

@lo_fabre Also many thanks for your tutorial efforts, looking forward to your English series when you find time to complete it.  Glad there are some pro’s around like you guys to teach us the ropes!
