+# GitHub Wiki Setup Instructions
+
+The development documentation has been prepared and is ready to be added to GitHub Wiki.
+
+## Quick Setup (Recommended)
+
+1. **Enable Wiki** (already enabled for this repo)
+
+2. **Create Wiki pages via GitHub Web UI:**
+   - Go to: https://github.com/m1ngsama/TNT/wiki
+   - Click "Create the first page"
+   - Title: `Home`
+   - Content: Copy from `README.md` (project overview)
+   - Click "Save Page"
+
+3. **Add Development Guide:**
+   - Click "New Page"
+   - Title: `Development-Guide`
+   - Content: Copy from `docs/Development-Guide.md`
+   - Click "Save Page"
+
+4. **Add other pages as needed:**
+   - Contributing Guide (from `docs/CONTRIBUTING.md`)
+   - Deployment Guide (from `docs/DEPLOYMENT.md`)
+   - Security Reference (from `docs/SECURITY_QUICKREF.md`)
+   - Quick Reference (from `docs/QUICKREF.md`)
+
+## Alternative: Clone and Push
+
+Once the Wiki has at least one page, you can manage it via git:
+
+```sh
+# Clone wiki repository
+git clone https://github.com/m1ngsama/TNT.wiki.git
+cd TNT.wiki
+
+# Copy documentation
+cp ../docs/Development-Guide.md ./Development-Guide.md
+cp ../docs/CONTRIBUTING.md ./Contributing.md
+cp ../docs/DEPLOYMENT.md ./Deployment.md
+
+# Commit and push
+git add .
+git commit -m "docs: add development documentation"
+git push origin master
+```
+
+## Wiki Page Structure
+
+Recommended structure:
+
+```
+Home                    - Project overview (from README.md)
+├── Development-Guide   - Complete dev manual
+├── Contributing        - How to contribute
+├── Deployment          - Production deployment
+├── Security-Reference  - Security configuration
+└── Quick-Reference     - Command cheat sheet
+```
+
+## Notes
+
+- GitHub Wiki uses its own git repository (separate from main repo)
+- Wiki pages are written in Markdown
+- Page titles become URLs (spaces → hyphens)
+- First page must be created via Web UI
+- After that, you can use git to manage content
+

+
+**All documentation is already in `docs/` directory and can be viewed directly in the repository.**
