 == INSTALLATION
 
-Some elements of libmormegil are self-contained single-header C++ classes
-which you can safely copy directly into your own projects if you want. Others
-are intended to be installed as system-wide shared libraries.
+If you want to set up a system-wide installation,
+
+        ./configure && make all && sudo make install
+
+should do the trick. If it doesn't, let me know what platform you're on and
+how to fix the issue.
