Tutorial for adding hash formats?

Guys,

First of all: thank you very much for open sourcing (ocl)hashcat!

I'd like to add a new algorithm. Is there some kind of quick tutorial available? A very simple example would be highly appreciated, e.g. adding a algorithm that takes a unsalted fixed limited length input and just checks if the brute forced candidate password matches the hash or copying an existing algorithm with a new hash type number: what needs to be edited and added where following which rules? E.g. @switch (hash_mode), what is what?


Thanks,
