There used to be a complicated process in adding techniques, but that's now been replaced with a tool that prompts you on the new technique details and updates the library code automagically. You can check out the python script at auxiliary/add_technique.py
Depending on how big the change is, if the change is fairly small then just a simple PR is fine. But if it has hundreds of lines of code changes then it's best to create an issue prior to even starting to write the code, or we can discuss on discord (kr.nl
). I don't bite ;)
You can create an issue, and I will reply within 24 hours. We have too much free time on our hands in reality.
