Instead of manually navigating to GitHub, copying the file name, and locating paths within the file, Codefresh GitOps simplifies the process with:

Instead of manually navigating to GitHub, copying the file name, and locating paths within the file, Codefresh GitOps simplifies the processof workingwith JSON files through auto-selection options:
