 This repository contains the current, Qt5-based development version of
 Krita. Stable Krita 2.9 is here:
 
   https://phabricator.kde.org/diffusion/CALLIGRA/
 
 The user manual is here:

+If you're building on Windows you'll need to build some third-party
+dependencies before you can build Krita. You should look at the README
+in the 3rdparty folder for directions on how to set them up.
