+### How to add a custom documentation generator ?
+
+The `-t <g>` (`--type <g>`) option lookups for a generator script `<g>`.sh to be present in the `/generators`  
+(ex: `--type doxygen` searchs for a `/generators/doxygen.sh` file script).  
+You can add your own generator by simply moving your script into the `/generators` folder
+
+Furthermore, your generator MUST follow below specifications :   
+* Define a `generate()` function that will be called, assuming that `$1` equals to the value passed after `-l` (`--loc`) which is the documentation sources location
+* Define a `GEN_PATH` variable which is the path of generated outputs
+* Place generated outputs in the `GEN_PATH` folder, the caller will then upload generated sources onto the user's CodeDoc space
