-Oclang is a tool which helps you to cross compile source code easily with clang on linux for OS X.
+OSXCross is a tool which helps you to cross compile source code easily with clang on linux for OS X.
 
 After the installation you will have "o32-clang", "o32-clang++", "o64-clang" and "o64-clang++" available as compiler.
 
+You can optionally build an update-to-date gcc as well, please see README.gcc.

+After finishing ./build.sh you can optionally build gcc as well.
+
+Don't forget to run "source ~/.profile" after adding the target to your .bashrc or .profile,
+or simply start a new shell session.
+
+Then make sure you have got the build dependencies for gcc installed on your system,
+see: http://gcc.gnu.org/install/prerequisites.html
+
+On debian like systems you can run 'apt-get build-dep gcc' to install them.
+
+After this edit GCC_VERSION and so on build_gcc.sh, so it fits your requirements, then finally
+run ./build_gcc.sh to start building gcc.
+
+If everything went well, then you'll have "x86_64-apple-darwinXX-gcc, i386-apple-darwinXX-g++" and so on
+available as compiler.
