Backup your workflows to GitHub -- in (subfolders)

Based on Jonathan & Solomon work. > The only addition I've made is a Set node. This node organizes workflows into subfolders within the GitHub repository based on their respective tags. How it works This workflow will backup your workflows to GitHub. It uses the n8n API node to export all workflows. It then loops over the data, checks in GitHub to see if a file exists that uses the credential's ID. Once checked it will: update the file on GitHub if it exists; create a new file if it doesn't exist; ignore if it's the same. Who is this for? People wanting to backup their workflows outside the server for safety purposes or to migrate to another server.

Help me set up the n8n workflow "Backup your workflows to GitHub -- in (subfolders)" (https://n8n.io/workflows/2868). It uses: GitHub, HTTP Request, Code. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
