-    - Unfortunately, many systems have compilers that predate C++-11 support.
+- A C++ compiler implementing at least the [C++-11 standard](http://www.stroustrup.com/C++11FAQ.html)
+    - Some systems may have compilers that predate C++-11 support.
     - You may need to build your own C++ compiler or upgrade your operating system's.
 - [Boost C++ libraries (version 1.44 or later)](http://www.boost.org/)
-    - If you build your own boost, you _must install it_ using `bjam install`.
+    - If you build your own boost, you _must install it_ using `bjam install` (to install it into a customized location use `--prefix=/path/to/target`).
     - Older versions of Boost _may_ work, but problems have been reported with command line option parsing on some platforms with older versions.

-## Building from a downloaded archive
-
-If your system contains the required tools and libraries in the usual places, you should be able to build as simply as:
-
-    ./configure
-    make -j4
-    ./tests/run-system-tests.pl

-## Building from a git clone
+## Building the software from a git clone
 
 In addition to the standard `cdec` third party software requirements, you will additionally need the following software to work with the `cdec` source code directly from git:
 
-- [Autoconf / Automake / Libtool](http://www.gnu.org/software/autoconf/)
-    - Older versions of GNU autotools may not work properly.
