 # Libft
-My own libC to use at 42.
-Most of the functions are defined in libft.h (and even if they're defined somewhere else you will find a comment in libft.h)
+My own libC to use at 42.  
+Most of the functions are defined in `libft.h`, appart from the t_vec4 related ones (because they are all inline).  
+`intrisics.h` contains the structures t_lst, t_vector, t_vec4, t_queue, (...) and all the defines.
+## Some stats
+- 128 files for ~4000 lines of code (not counting the headers).  
+- Some functions as fast or faster than the libC (depending on your system) without the use of any ASM.
 ## What's inside
-My libft contains lots of functions and datatypes with their own 'operators', all of them are described in libft.h and again by the folder names in ./src
+My libft contains lots of functions and datatypes with their own 'operators', most of them are described in `libft.h`. The folder names in `./src` are also quite descriptive.

-- ft_mem(...) Functions in here are generaly optimized to use the biggest registers available and use as few cpu cycles as possible (yay AVX)
