+# GitHub Authentication Setup
+
+## Current Status
+
+✅ **Commit ready to push:** `2633de4 feat(eresidency): Complete eResidency service implementation`
+✅ **SSH key generated:** `~/.ssh/id_ed25519`
+✅ **Remote configured:** `git@github.com:Order-of-Hospitallers/the-order-monorepo.git`
+⚠️ **Push blocked:** SSH key needs to be added to GitHub
+
+## Your SSH Public Key
+
+```
+ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIGb+gFevwMFw/Li1JLyIvpYZ4O6/f1KHutekqtPapY/l defi@defi-oracle.io
+```
+
+## Quick Setup (SSH - Recommended)
+
+1. **Copy your SSH public key:**
+
+   ```bash
+   cat ~/.ssh/id_ed25519.pub
+   ```
+
+2. **Add to GitHub:**
+   - Visit: https://github.com/settings/keys
+   - Click "New SSH key"
+   - Title: `WSL2 - the-order-monorepo`
+   - Paste the public key
+   - Click "Add SSH key"
+
+3. **Test connection:**
+
+   ```bash
+   ssh -T git@github.com
+   ```
+
+   You should see: `Hi defiQUG! You've successfully authenticated...`
+
+4. **Push your commit:**
+   ```bash
+   git push
+   ```
+   Or use the script:
+   ```bash
+   ./scripts/push-to-github.sh
+   ```
+
+## Alternative: Personal Access Token (HTTPS)
+
+If you prefer HTTPS:
+
+1. **Create a Personal Access Token:**
+   - Visit: https://github.com/settings/tokens
+   - Click "Generate new token (classic)"
+   - Select `repo` scope
+   - Generate and copy the token
+
+2. **Configure credential helper:**
+
+   ```bash
+   git config --global credential.helper store
+   ```
+
+3. **Update remote URL:**
+
+   ```bash
+   git remote set-url origin https://github.com/Order-of-Hospitallers/the-order-monorepo.git
+   ```
+
+4. **Push (enter token as password):**
+   ```bash
+   git push
+   Username: defiQUG
+   Password: <paste-your-token-here>
+   ```
+
+## Verification
+
+After pushing, verify with:
+
+```bash
+git log --oneline origin/main..HEAD
+```
+
+Should show no commits (all pushed).
+
+## Troubleshooting
+
+- **Permission denied:** Make sure SSH key is added to GitHub
+- **Key not found:** Run `ssh-add ~/.ssh/id_ed25519`
+- **Connection timeout:** Check your internet connection
+- **Wrong key:** Verify key fingerprint matches GitHub
+
+## Next Steps
+
+Once pushed, your changes will be available on GitHub and can be:
+
+- Reviewed in pull requests
+- Deployed via CI/CD
+- Collaborated on with team members
