Implementation Details

This workflow uses Andrew-Chen-Wang/github-wiki-action@v4 to:

• 📂 Keep wiki docs in sync with code in the wiki/ folder
• 🔁 Automatically publish on push to main
• ✨ Preprocess markdown (converts README.md → Home.md, rewrites .md links)

Workflow Triggers

• Push to main branch when files change in:
  • wiki/**
  • .github/workflows/wiki-updates.yml
• Manual trigger via workflow_dispatch

Features

Feature	Value
Source Path	wiki/
Strategy	clone (default - preserves history)
Preprocess	true (README.md → Home.md, link rewriting)
Concurrency	Single run, cancel in-progress

Checklist

• Labels applied correctly
• Documentation updated (if applicable)

Prerequisites

⚠️ Important: Before this workflow can run successfully:

1. A dummy wiki page must be created manually in the GitHub Wiki tab (this initializes the wiki Git backend)
2. The wiki/ folder should exist with at least one markdown file

Testing

Workflow will trigger on merge to main when wiki/ folder contents change.
