+Note: The CMake build of AliRoot builds out-of-source
+
 Steps to Build AliRoot with CMake :
 
-1. Define environment variable ALICE_INSTALL
-       export ALICE_INSTALL=$ALICE/AliRootInstall
+1. Check out Aliroot source into any folder
+       
+       svn co http://alisoft.cern.ch/AliRoot/trunk ~/trunk
 
-2. Set Path to point to binaries and libraries that will be built in ALICE_INSTALL
-       export PATH=$PATH:$ALICE_INSTALL/bin/tgt_${ALICE_TARGET}
-       export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ALICE_INSTALL/lib/tgt_${ALICE_TARGET}
+2. Create a new folder and set the environment variable ALICE_ROOT to point to it
+       
+       mkdir AliRoot
+       cd AliRoot
+       export ALICE_ROOT=`pwd`
 
 3. Execute the following commands to build AliRoot
-       cd $ALICE_INSTALL
-       cmake <path_to_source> 
+
+       cmake ~/trunk
        make
 
-4. In order to build addtional targets like TFluka, THydjet and SHUTTLE add the following options to the cmake command
-       cmake -DTFLUKA=ON -DTHYDJET=ON -DSHUTTLE=ON <path_to_source>
+4. In order to build addtional targets like THydjet and SHUTTLE add the following options to the cmake command
+
+       cmake -DTHydjet=ON -DSHUTTLE=ON <path_to_source>
+
 
-!IMPORTANT! : Make sure you delete all the files in your ALICE_INSTALL directory before you generate the Makefile again to clear the CMakeCache or the generated build system may not function properly.
+!IMPORTANT! - Make sure your source folder is clean. If you used the old make system to build aliroot run make clean in the source directory before you run cmake
