 There is no real documentation but "methods" on any object should help you :)
 
-The only object available for now is Cucul::Canvas (meaning that only
-functions that have a cucul_canvas_t* as first argument except
-cucul_dither_bitmap are available).
+The objects available for now are :
+
+- Cucul::Canvas (functions that have a cucul_canvas_t* as first argument)
+ * dither_bitmap is missing as Cucul::Dither is not yet implemented
+
+- Cucul::Font (functions that have a cucul_font_t* as first argument)
+ * The constructor can currently only accept the name of a builtin font
 
 I tried to follow Ruby spirit meaning that :
-- most of the Cucul::Canvas methods return self
+- most of the methods return self
 - the methods set_foo with only an argument are also available as foo=
 (returning the value instead of self)
 - the methods originally named get_foo are available only as foo
