I'm a self-taught developer without any academic credentials. I have intermediate knowledge in Computer Vision and fairly decent grasp of Mathematics.

I want to quite my comfortable corporate job and work with academics. Recently I reached out to some biologists at the local university saying I can write custom software for them on a voluntary basis. One thing led to another and I'm not doing some computer vision based analysis and generating graphs using Matplotlib.

There is nothing novel about the work I did for them and I'm more or less like a technician. However, I did provide them some of my ideas and helped them improve their experimental setup and they're quite happy with our collaboration.

They are likely to publish in Nature or Cell. They will include my name in the Acknowledgement section and I was wondering whether it's better to post the code on GitHub and ask for a citation instead.

TLDR: Some code I wrote will be used in a research paper. Which is better, an acknowledgement or citation to my GitHub repository?
