Extracting the line art from a numerised drawing

[Psychommunist]

Hello, I'm a beginner with Krita.

I wanted start with digital painting for add some colors on my pen/paper drawings. But I have a problem for remove the "white" of the paper, I wish I have transparency instead. Alas, I'm not a good anglophone so I'm totally clueless when I have to find a accurate tutorial (sorry for my mistake(s) in english, btw).

Can someone help me to know how can I extract the black line art from the rest of the white paper, step by step ?

OS version : W8.1 64 bits
Krita vertion : 2.9.1

Thank you.
Krita is my very first colorization software,
so I don't have an "infographic vision" yet.
I searched this kind of tutorial for hours.
You helped me more you think.

Well, next time you can try to ask anything related at Krita forum on KDE:
https://forum.kde.org/viewforum.php?f=136

It's a lot more populated (compared to steam counterpart and you'll get answers reasonably fast) and devs are there. Also it has awesome tutorial/resources subforum with bunch of cool brush packs by David Revoy, Wolthera and other talanted people.

P.s. On second thought - we might need a pinned thread somewhere here with all the useful links just for the sake of saving people's time.

1) https://krita.org/ -as it has a lot of interesting interviews and stuff
2) Abovementioned KDE forum
3) Bugtracker [bugs.kde.org] - because why not?
4) http://quickgit.kde.org/?p=calligra.git , maybe? Honestly, no one here will need it for the right cause, but it 's always nice to see software being actively developed.
Especially, since DraccoonStu has a life things happening and it being the reason we temporarily (i hope) don't get a lot news and updates here, on steam.
