While waiting for my Automation Hat to arrive, I've been testing Hydrosys on my Pi with the sensors I have on hand. So far, so good with your software.

I'm a programmer as well, but I'm not very familiar with the Pi. I was wondering what the process would be for modifying the source code, then deploying the modifications to the Pi.

What I figure is that I'd create a fork of your project and fool around with that.

But what is the best way to install my own fork onto the Pi without re-imaging the Pi and wiping out all the data that's already on it? I don't want to create conflicts with your existing software, but I'd like to test out some new data visualizations and whatnot.
