 # Platforms

 You should be able to compile Aseprite successfully on the following
 platforms:

-* Windows + VS2013 + DirectX SDK
-* Mac OS X 10.8 Mountain Lion + Xcode 5.1.1 + Mac OS X 10.4 SDK universal
-* Linux + gcc with some C++11 support, this port is not compiled
-  regularly so you can expect some errors in the master branch.
+* Windows 10 + VS2015 Community Edition + Windows 10 SDK
+* Mac OS X 10.11.4 El Capitan + Xcode 7.3 + OS X 10.11 SDK + Skia (without GPU)
+* Linux + gcc 4.8 with some C++11 support

+Aseprite can be compiled with two different back-ends:
+
+1. Allegro back-end (Windows, Linux): You will not need any extra
+   library because the repository already contains a modified version
+   of the Allegro library. This back-end is only available for Windows
+   and Linux and it'll be removed in following versions.
+
+2. Skia back-end (Windows, OS X): You will need a compiled version of
+   [Skia](http://skia.org/), `chrome/m50` branch, without GPU support,
+   i.e.  compiled with `GYP_DEFINES='skia_gpu=0'`. When you compile
+   Aseprite, you'll need to give some variables to CMake:
+   `-DUSE_SKIA_ALLEG4=OFF`, `-DUSE_SKIA_BACKEND=ON`, and
+   `-DSKIA_DIR=...` pointing to the Skia checkout directory. (Note:
+   The GPU support is a work-in-progress, so next versions .)

+You will need the following dependencies:
+
+    sudo apt-get update -qq
+    sudo apt-get install -y g++ libx11-dev libxcursor-dev cmake ninja-build
