Not directly related to the 3rd party git module, but IA staff released some resources for using git on this thread: Guide for Version Control with Ignition
We're currently testing a workflow where our repo root is at the /data folder (gwbk) and devs interact with a local container gateway and monitor/manage commits via VSCode/VSCodium opened to that folder (we also have a UI developer who mostly uses VS Code for editing CSS more than editing in Ignition Designer).
