 *Header file:* [printf.h](api/printf_8h.html)
 
+In this utility header you can find `printf()`-like functions that can write the formatted output to an arbitrary
+stream (or UCX buffer, resp.), or to memory allocated by an allocator within a single function call.
+With the help of these convenience functions, you do not need to `snprintf` your string to a temporary buffer anymore,
+plus you do not need to worry about too small buffer sizes, because the functions will automatically allocate enough
+memory to contain the entire formatted string.

 ### Compare Functions
 
 *Header file:* [compare.h](api/compare_8h.html)
+
+This header file contains a collection of compare functions for various data types.
+Their signatures are designed to be compatible with the `cx_compare_func` function pointer type.
