+#Getting OpenMW Working on OS X
 
-OpenMW
-======
+## Initial setup
+First of all, clone OpenMW repo.
 
-From the [official website][]:
+        $ git clone github.com/zinnschlag/openmw
 
-> OpenMW is an attempt to reimplement the popular role playing game
-  Morrowind. It aims to be a fully playable, open source
-  implementation of the game. You must own Morrowind to use OpenMW.
+Or use your github url if you forked.
 
+About dependencies: I prefer not to install them globally (i. e. in /usr/local/), so I'm installing them in directory in my home directory. If OpenMW sources is in $HOME/path/openmw, I'm using $HOME/path/libs/root as prefix for boost and other libs.
 
-About This Project
-------------------
+It's useful to create env var for lib install prefix:
+        
+        $ export OMW_LIB_PREFIX=$HOME/path/libs/root`
 
-This specific repository is a branch of OpenMW intended to keep pace
-with development of the project in order to provide a Mac build for
-interested parties to contribute. This is not an official, sanctioned
-branch of the OpenMW project. I will only be able to answer specific
-questions about getting this project running on Mac OS X, **no other
-platform**. I will not even be able to guarantee my changes maintain
-backwards compatibility against builds in other operating systems. You
-have been warned.
+Most of libs can be installed from [Homebrew][homebrew]. Only mpg123 needs to be installed from source (due to lack of universal compilation support). I think that some of libs can be installed from MacPorts or Fink too.
 
+As OpenMW currently only supports i386 architecture on OS X, denendencies also should support it. Set some env vars in current terminal:

         $ export CXXFLAGS="-arch i386"
         $ export LDFLAGS="-arch i386"
-  All libs will build with correct architecture.
-  If you close your terminal, you should set env vars again before pcoceeding to next steps!

+## Boost
+Download [boost][boost] and install it with the following command:
 
         $ cd /path/to/boost/source
         $ ./bootstrap.sh --prefix=$OMW_LIB_PREFIX
         $ ./bjam --build-dir=build --layout=versioned \

         --link-shared,static --prefix=$OMW_LIB_PREFIX install
+    
+        
+Alternatively you can install boost with homebrew:
 
+        $ brew install boost --universal
 
-5. Download [Ogre][] SDK (tested with 1.7.2), unpack it and move
-`lib/Release/Ogre.framework` into `Library/Frameworks`.
+I think MacPorts also should support universal build for boost.
 
-6. Download [OIS][] and use the XCode project provided in
-   `ois/Mac/XCode-2.2`. Be sure to set your build architecture to
-   `i386` and your SDK platform to either 10.5 or 10.6. Once it
-   builds, move `ois/Mac/XCode-2.2/build/Debug/OIS.framework` to
-   `/Library/Frameworks`.
+## Ogre
+Download [Ogre][] SDK (tested with 1.7.3), unpack it somewhere and move
+`lib/Release/Ogre.framework` into `/Library/Frameworks`.
+
+## OIS
+Download patched [OIS][] and use the XCode project provided. Be sure to set your build architecture to
+   `i386`. Once it built, locate built OIS.framework with Xcode and move it to `/Library/Frameworks`.

+## mpg123
+Download [MPG 123][mpg123] and build it:

+Install [Qt][qt]. Qt SDK distributed by Nokia is not an option because it's 64 bit only, and OpenMW currently doesn't build for 64 bit on OS X. I'm installing it from Homebrew:

+build. As for CMake 2.8.7 and Xcode 4.3, Xcode generator is broken. Sadly Eclipse CDT also cannot import generated project at least on my machine.
