+Compiling
+---------
+The libraries should compile warning free in any moderately recent version of
+gcc. The project uses `<stdint.h>` which is technically a C99 file and not
+available in Microsoft Visual Studio. The easiest solution here is to use the
+msinttypes version of stdint.h from <https://code.google.com/p/msinttypes/>.
+The direct link for the lazy people is:
+<https://msinttypes.googlecode.com/svn/trunk/stdint.h>.
+
+If your compiler does not provide an implementation of `<stdint.h>` you can
+remove the header from the bsdiff/bspatch files and provide your own typedefs
+for the following symbols: `uint8_t`, `uint64_t` and `int64_t`.
