 WARNING - You will require a recent compiler for QUIT as it uses C++17 features. On Mac simply having the most recent software updates is enough, on Linux you will need GCC 7.0.0. No one has been brave enough to compile QUIT on Windows to date.
 
-Installing GCC 7
-----------------
-
-Most Linux systems currently ship with GCC 4.8 or lower as their system compiler. As of QUIT 2.1 you will require GCC 7 as QUIT uses C++17 features. Joost Kuijer has kindly provided the following recipe for installing newer GCC versions in a user directory and using it to compile QUIT.
-
-1. Follow the GCC guide here: https://gcc.gnu.org/wiki/InstallingGCC
-2. Before running the ``build.sh`` script let cmake know about the new compiler
-    .. code-block:: bash
-
-        export PATH=$HOME/GCC-7.0.0/bin:$PATH
-        export LD_LIBRARY_PATH=$HOME/GCC-7.0.0/lib:$HOME/GCC-7.0.0/lib64:$LD_LIBRARY_PATH
-        export CC=$HOME/GCC-7.0.0/bin/gcc
-        export CXX=$HOME/GCC-7.0.0/bin/g++
-
-3. Before executing the compiled code also do (you can add this line to your `.bashrc` file:
-    .. code-block:: bash
-
-        export LD_LIBRARY_PATH=$HOME/GCC-7.0.0/lib:$HOME/GCC-7.0.0/lib64:$LD_LIBRARY_PATH

 External Libraries
 ------------------
 
-QUIT is built using several C++ libraries. These are currently included in the project as git submodules. The easiest way to initialise these is with the ``build.sh`` script. However, if you are already have some of them available you may wish to not run the script and instead configure them yourself. This is discussed further below. The libraries are:

 Compilation
 -----------
 
-If you are unfamiliar with C++/CMake/git etc. a script is provided that should be able to build the tools provided the right software is available on your system. To use it, in a terminal window, change directory to where you unpacked QUIT. Then type ``./build.sh``. This should correctly checkout the git repositories for each external library, build Ceres and ITK, and then configure and build QUIT.

-CMake projects separate the ``build`` and ``install`` phases. The binaries are only moved to a single folder during ``install``. By default, the install directory is ``/usr/local/bin``. If you run ``./build.sh -i``it will run the install step to this directory. You can also ``cd`` into the ``build/`` directory and then type ``make install`` (or ``ninja install``) to avoid re-running the entire ``build.sh`` script.

 If you want to change where the binaries are installed, you can either:
-- Run ``./build.sh -i -p /path/to/install``
+- Run ``./bootstrap.sh -i -p /path/to/install``
 - ``cd /build; ccmake ./``, change the ``INSTALL_PREFIX_DIR``, configure (press c), generate (press g), exit, then ``make install``
 
 Note that the binaries will end up in ``/bin`` inside the install prefix.
