 Download qt4.2 opensource precompiled edition exe and install (including the

 Edit C:\Qt\4.2.0\bin\qtvars.bat and add the following line (the second is only 
 needed if you like vim in your shell):

-QGIS:
--------------
-Check out to c:\dev\cpp\qgis
-Currently you need to put it into that location I think - if you try to build
-somewhere else you *may* run into problems - particularly with the NSIS installer 
-as I havent checked all paths are relative yet.
+Next you need to shift some files around. For convenience we've made an archive
+that handles all the changes for you. Download it and unpack to qgis source directory:

+List of what has been changed / added by this archive to enable compilation:
 
-Core:
--------------
- - moved qgsspatialrefsys* and qgscoordinatetransform* into core dir from gui
+ - moved qgscsexception.h, qgsspatialrefsys* and qgscoordinatetransform* into core dir from gui
+ - moved qgspluginregistry.* from core to gui
+ - qgsspatialrefsys.cpp - commented out SRS validation using projection selector
  - qgsspatialrefsys.cpp - commented out lines using qgsproject as it depends on gui stuff
  - qgsdistancearea.cpp - commented out lines using qgsproject as it depends on 
    gui stuff and moved to core
- - qgscsexception.h  into core from gui (only tested on mac)
-
-I have created a small archive which includes the above changes, which I will make available.
-
+ - lexer and parser generated by genlexyacc.bat
+ - added custom qgsconfig.h and qgssvnversion.h
 
 
 Building:
--------------
+---------
 
-Now open the qt command shell
+Now open the qt command shell (or start "cmd" and run c:\Qt\4.2.0\qtvars.bat)
 
 cd c:\dev\cpp\qgis
 qmake
 make
 
+This will compile both debug and release version. To make just a one of them
+use "make debug" or "make release" respectively.
+
+Note: debug version uses debug version of Qt library thus if linking fails
+on not founding library QtSvgd4 (or similar), you need to install them.
+
+Running: (optional)
+--------
+
+After successfull make you can run QGIS directly from the directory
+where it has been built: qgis-debug and/or qgis-release in qgis root dir.
+You only need to add data files - we have provided an archive for convenience
+which you can just unpack there and run QGIS:
 
-Create the installation package:
----------------------------------
+http://qgis.org/uploadfiles/msys/qgis_data.zip
+
+Then just run qgis.exe
+
+GDB: (optional)
+----
+
+If you plan to do some debugging, download and install gdb-6.3.2.exe from 
+
+http://prdownloads.sourceforge.net/mingw/gdb-6.3-2.exe?download
+
+and install to c:\msys\mingw
+
+
+Create the installation package: (optional)
+--------------------------------
+
+Downlad and install NSIS from (http://nsis.sourceforge.net/Main_Page)
 
 Download both the QGIS debug and release installer packages from
