  * @stability: Unstable
- * @include: chimara/chimara-if.h
+ * @include: libchimara/chimara-if.h
  *
  * The #ChimaraIF widget, given an interactive fiction game file to run, selects
  * an appropriate interpreter plugin and runs it. Interpreter options are set by
  * setting properties on the widget.
+ *
+ * Using it in a GTK program is similar to using #ChimaraGlk (which see). 
+ * Threads must be initialized before using #ChimaraIF and the call to 
+ * gtk_main() must be bracketed between gdk_threads_enter() and 
+ * gdk_threads_leave(). Use chimara_if_run_game() to start playing an
+ * interactive fiction game.
