+# cNaCl
+
+    If you would like to be confusing, you could pronounce it sea-salt
+
+This is a fork NaCl by Daniel J. Bernstein and Tanja Lange.
+The build has been ported to cmake so it can be cross compiled and build output is reliable.
+Since it uses cmake, it could theoretically be built on windows but this has not been tested.
+It does compile using mingw32.
+
+## How do I make this thing work?
+
+    mkdir cbuild
+    cd cbuild
+    cmake ..
+    make
+
+## Ok now how about cross compiling?
+
+    mkdir cbuildw32
+    cd cbuildw32
+    cmake -DCMAKE_TOOLCHAIN_FILE=../CMakeWindows.txt ..
+    make
+
+## Why fork?
+
+NaCl builds using a shell script called `./do`. This script does compiling, testing, measuring
+and selection of the best implementation of each algorithm for the given machine. It also generates
+the header files which will be used.
+
+The problems with `./do` are it's slow, it tries compiling with multiple different compiler
+profiles, it's very platform independent but it doesn't run on Windows and most importantly, with
+compiling, testing and measuring so tightly bound, it is impossible to cross compile for a
+different operating system.
+
+
+## How it works
+
+The first time you build for a new ABI, it will trigger the traditional nacl `./do` script.
+What cNaCl does is parse the resulting headers from the `./do` build and create a plan so that it
+can repeat roughly the same build.
+
+If there is already a plan for the given ABI, the build uses this plan and the build is very fast.
+
+Plans are stored in `./cmake/plans/` and I will be adding plans as I find new ones.
+
+
+## What else is new?
+
+There is a problem with the `./do` build which prevents it from running on some ARM based machines,
+this was fixed by adding a more lax method for measuring CPU speed as a fall back.
