+Installing libnoise:
+
+1.  Make!
+
+CXXFLAGS='-O3 -fomit-frame-pointer ...options of choice...' make
+
+Using compiler optimizations for libnoise is *strongly recommended*.  Using the
+unoptimized library is roughly a fifth as fast as using -O3 on my test
+computer.
+
+2.  Install!
+
+The 'include' directory should be copied to your software include directory,
+usually /usr/local/include, with an appropriate name.  I use
+
+  cp -R include /usr/local/include/noise
+
+Similarly, the *contents* of the 'lib' directory should go into your library
+directory (usually /usr/local/lib).  Once you've done that, run 'ldconfig',
+then make a symlink from LIBDIR/libnoise.so to LIBDIR/libnoise.so.0.  I use:
+
+  cp lib/* /usr/local/lib
+  ldconfig
+  ln -s /usr/local/lib/libnoise.so.0 /usr/local/lib/libnoise.so
+
+At this point, you should be able to include libnoise in your projects using
+
+  #include <noise/noise.h>
+
+and
+
+  g++ ...options... -lnoise
+
+At some point we'll automate this process.

+This distribution of noise library is only meant for interfacing noise with OrcaSlicer.
+
+The noise source file was acquired from https://sourceforge.net/projects/libnoise/ version 1.0.
+
+No changes to the noise library were made except for deleting the 'doc' directory.
