Instructions for running from source

[SIGSTACKFAULT]

Title. I'm pretty sure this is an electron app but I have no idea which of these files to do anything with.

This is indeed an electron app. The tools usage is baked into the app, but the model training can run headless, if you'd like, using the xva_train.py entry points in the python/fastpitch1_1 and python/hifigan folders.

If you wanted to run the electron app from source, instead of using the compiled version, you can run npm start, once you npm install the dependencies (including the python ones). xVASynth has more details on this - xVATrainer is a fork of xVASynth.
