+This page explains how to build the cross compiler for building and running Thor. 
+
+## Download
+
+Download binutils and GCC
+
+    mkdir $HOME/src/
+    cd $HOME/src/
+    wget ftp://ftp.gnu.org/gnu/binutils/binutils-2.9.tar.gz
+    wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.gz
+    tar xvzf binutils*
+    tar xvzf gcc*
+
+## Configuration
+
+    export PREFIX="$HOME/opt/cross"
+    export TARGET=x86_64-elf
+    export PATH="$PREFIX/bin:$PATH"
+
+## Build binutils
+
+    cd $HOME/src
+    mkdir build-binutils
+    cd build-binutils
+    ../binutils-*/configure --target=$TARGET --prefix="$PREFIX" --disable-nls
+    make
+    make install
+
+## Build GCC
+
+    cd $HOME/src
+    mkdir build-gcc
+    cd build-gcc
+    ../gcc-*/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++
+    make all-gcc
+    make all-target-libgcc
+    make install-gcc
+    make install-target-libgcc
+
+Normally, you should now have a working x86_64-elf cross compiler.
