 Installing
 ==========
 ### Prerequisites
-* pkg-config
-* glib-2.0 (for the test suite; everything else will build without glib)
 * make
 
+### Optional Dependencies
+* doxygen (for `make doc`)
+* pkg-config (for `make test`)
+* glib-2.0 (for `make test`)
+* glib-2.0-dev (for `make test`)
+
 To install, type `make`. To run the built-in test suite, type `make test`.
 
 There is not currently a `make install` target; to make Hammer available system-wide, copy `libhammer.a` to `/usr/lib/` (or `/usr/local/lib/`, or wherever ld will find it) and `hammer.h` to `/usr/include/`.
