 ## cooklangbook.py
 
 Takes multiple recipe paths as arguments and returns a complete latex document on stdout.
+Optionally takes the '-r' flag and two directory paths,
+the first one being the source and the second one the destination directory.
+It then generates multiple .tex files, 
+one per recipe and one called `recipe-book.tex` including all recipies.
 
-### Example
+### Examples
+
+Basic operation:
 
 `python3 cooklangbook.py /path/to/recipes/{rec1,rec2,rec3}`
+
+Recursive book generation:
+
+`python3 cooklangbook.py /path/to/source/dir /path/to/dest/dir`
