+# GitHub Actions - ISO Build Automation
+
+## How It Works
+
+The `build-iso.yml` workflow automatically builds the AeThex Linux ISO whenever you:
+1. Push changes to `main` branch (if relevant files changed)
+2. Manually trigger it from GitHub Actions tab
+
+## Automatic Triggers
+
+The workflow runs automatically when changes are pushed to:
+- `client/**` - React frontend
+- `server/**` - Node.js backend
+- `shared/**` - Shared schema
+- `src-tauri/**` - Tauri desktop app
+- `script/build-linux-iso.sh` - Build script itself
+- `configs/**` - System configuration
+- `.github/workflows/build-iso.yml` - This workflow file
+
+## Manual Trigger
+
+1. Go to **GitHub** → **Actions** tab
+2. Select **"Build AeThex Linux ISO"** workflow
+3. Click **"Run workflow"** button
+4. Optionally check **"Create a GitHub release"** to publish the ISO
+
+## Outputs
+
+### Artifacts
+- **ISO file:** Available as artifact for 90 days
+- **Checksum:** SHA256 verification file
+- Download from: Actions → Workflow run → Artifacts
+
+### Releases (Optional)
+If you check "Create a GitHub release":
+- Creates a GitHub Release with the ISO
+- Makes it publicly downloadable
+- Includes SHA256 checksum for verification
+- Pre-release tag for testing builds
+
+## Usage Examples
+
+### Download Built ISO
+
+```bash
+# Via GitHub Actions artifacts
+1. Go to Actions tab
+2. Select latest "Build AeThex Linux ISO" run
+3. Download "AeThex-Linux-ISO" artifact
+
+# Via GitHub CLI
+gh run list --workflow=build-iso.yml --branch=main
+gh run download <RUN_ID> -n AeThex-Linux-ISO
+```
+
+### Create Bootable USB from Downloaded ISO
+
+```bash
+# Verify integrity
+sha256sum -c AeThex-Linux-*.sha256
+
+# Write to USB
+sudo dd if=AeThex-Linux-*.iso of=/dev/sdX bs=4M status=progress
+
+# Eject
+sudo eject /dev/sdX
+```
+
+### Automate Releases on Tags
+
+Edit the workflow to release on git tags:
+
+```yaml
+on:
+  push:
+    tags:
+      - 'v*'  # Trigger on version tags like v1.0.0
+```
+
+Then:
+```bash
+git tag v1.0.0
+git push origin v1.0.0
+```
+
+## Build Status Badge
+
+Add to your README:
+
+```markdown
+[![Build AeThex Linux ISO](https://github.com/AeThex-Corporation/AeThex-OS/actions/workflows/build-iso.yml/badge.svg)](https://github.com/AeThex-Corporation/AeThex-OS/actions/workflows/build-iso.yml)
+```
+
+## Monitoring Builds
+
+### Check Recent Builds
+1. **GitHub UI:** Actions tab → Select workflow
+2. **GitHub CLI:** 
+   ```bash
+   gh run list --workflow=build-iso.yml
+   gh run view <RUN_ID> --log
+   ```
+3. **Terminal:**
+   ```bash
+   gh workflow list
+   gh run list -w build-iso.yml -L 5
+   ```
+
+### Get Build Logs
+```bash
+# Download full logs
+gh run download <RUN_ID> --dir ./logs
+
+# View in terminal
+gh run view <RUN_ID> --log
+```
+
+## Customization
+
+### Change Trigger Conditions
+Edit `.github/workflows/build-iso.yml`:
+
+```yaml
+on:
+  push:
+    branches:
+      - main
+      - develop  # Also build on develop branch
+    paths:
+      - 'src-tauri/**'  # Only rebuild when Tauri changes
+```
+
+### Add Slack Notifications
+```yaml
+- name: Notify Slack
+  if: always()
+  uses: slackapi/slack-github-action@v1
+  with:
+    webhook-url: ${{ secrets.SLACK_WEBHOOK }}
+    payload: |
+      {
+        "text": "AeThex Linux ISO Build: ${{ job.status }}"
+      }
+```
+
+### Upload to S3 or CDN
+```yaml
+- name: Upload to S3
+  uses: jakejarvis/s3-sync-action@master
+  with:
+    args: --acl public-read
+  env:
+    AWS_S3_BUCKET: ${{ secrets.AWS_S3_BUCKET }}
+    AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
+    AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
+    AWS_REGION: 'us-east-1'
+    SOURCE_DIR: '~/aethex-linux-build'
+```
+
+## Troubleshooting
+
+### Build Timeout (60 minutes)
+If builds take too long, try:
+- Pre-compile dependencies
+- Cache Docker layers
+- Use GitHub-hosted larger runners (if available)
+
+### Out of Disk Space on Runner
+The workflow runs on Ubuntu Latest with ~14GB free (enough for this build).
+If it fails:
+1. Check workflow logs
+2. Remove unnecessary steps
+3. Use `disk-usage-cleanup` action
+
+### Artifacts Not Uploading
+- Check artifact path is correct
+- Verify file was actually created
+- Check artifact retention settings
+
+## Security
+
+### Best Practices
+
+1. **Limit artifact access:**
+   ```yaml
+   permissions:
+     contents: read
+   ```
+
+2. **Sign releases:**
+   ```yaml
+   - name: Create signed release
+     with:
+      gpg_key: ${{ secrets.GPG_KEY }}
+   ```
+
+3. **Restrict workflow to trusted users:**
+   - Only allow manual runs from specific users
+   - Use branch protection rules
+
+## Next Steps
+
+1. **Push changes to trigger build:**
+   ```bash
+   git add .
+   git commit -m "Add AeThex Linux build automation"
+   git push origin main
+   ```
+
+2. **Monitor first build:**
+   - Go to Actions tab
+   - Watch build progress
+   - Download artifact when complete
+
+3. **Set up releases (optional):**
+   - Modify workflow to create releases
+   - Distribute ISOs publicly
+   - Track versions
+
+4. **Add to README:**
+   ```markdown
+   ## Download AeThex Linux
+   
+   Get the latest bootable ISO:
+   - [![Build Status](badge-url)](actions-url)
+   - Download from [Releases](releases)
+   ```
+
+---
+
+**Total build time:** ~30-45 minutes on GitHub Actions runners
+**No local storage required:** Building happens in the cloud

+# AeThex Linux - Bootable OS Distribution
+
+## What Is AeThex Linux?
+
+AeThex Linux is a **custom Linux distribution** that boots directly into the AeThex-OS desktop environment. Instead of accessing your CloudOS through a browser, it becomes the primary operating system interface.
+
+### Three Deployment Modes
+
+| Mode | Description | Use Case |
+|------|-------------|----------|
+| **Web** | Browser-based, hosted on Railway | Public access, multi-tenant SaaS |
+| **Desktop** | Tauri app (Windows/Mac/Linux) | Single-user, native app |
+| **Linux Distro** | Bootable OS replacing Windows/Mac | Full system replacement, kiosks, custom hardware |
+

+# AeThex Linux - Quick Start Guide
+
+## Build and Test AeThex Linux (Proof of Concept)
+
+This guide will help you build a bootable ISO and test it in a VM within 30 minutes.
+
+### Prerequisites
+
+**System Requirements:**
+- Ubuntu 22.04+ or Debian-based Linux
+- 20GB free disk space
+- 8GB RAM (4GB for build, 4GB for VM)
+- Root access (sudo)
+
+**Required Tools:**
+```bash
+# Install all dependencies
+sudo apt update
+sudo apt install -y \
+  build-essential \
+  curl \
+  git \
+  nodejs \
+  npm \
+  debootstrap \
+  squashfs-tools \
+  xorriso \
+  grub-pc-bin \
+  grub-efi-amd64-bin \
+  virtualbox
+```
+
+**Rust (for Tauri build):**
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+source $HOME/.cargo/env
+```
+
+### Step 1: Build the ISO
+
+```bash
+# Navigate to project directory
+cd /workspaces/AeThex-OS
+
+# Make scripts executable
+chmod +x script/*.sh
+
+# Build ISO (takes 10-15 minutes)
+sudo bash script/build-linux-iso.sh
+```
+
+**What this does:**
+1. Bootstraps Ubuntu 24.04 base system
+2. Installs required packages (X server, desktop manager)
+3. Builds your Tauri desktop app
+4. Configures auto-login and system services
+5. Creates bootable ISO image
+
+**Output:**
+- ISO: `~/aethex-linux-build/AeThex-Linux-1.0.0-alpha-amd64.iso`
+- Size: ~2-4GB
+- Checksum: `~/aethex-linux-build/AeThex-Linux-1.0.0-alpha-amd64.iso.sha256`
+
+### Step 2: Test in Virtual Machine
+
+```bash
+# Launch VirtualBox VM with the ISO
+sudo bash script/test-in-vm.sh
+```
+
+**What this does:**
+1. Creates new VirtualBox VM (4GB RAM, 20GB disk)
+2. Attaches the AeThex Linux ISO
+3. Boots the VM
+4. Auto-logs in to AeThex Desktop
+
+**VM Login:**
+- Username: `aethex`
+- Password: `aethex`
+
+**Test Checklist:**
+- [ ] System boots to desktop (no errors)
+- [ ] Window manager works (drag windows)
+- [ ] Terminal opens (`Ctrl+Alt+T`)
+- [ ] File manager shows directories
+- [ ] Applications menu appears
+- [ ] Network connects automatically
+
+### Step 3: Create Bootable USB (Optional)
+
+```bash
+# Check available USB drives
+lsblk
+
+# Write ISO to USB (replace /dev/sdX with your device)
+sudo bash script/create-usb.sh /dev/sdX
+```
+
+⚠️ **WARNING:** This erases all data on the USB drive!
+
+### Step 4: Boot on Real Hardware
+
+1. Insert USB drive
+2. Restart computer
+3. Press `F12`, `F2`, or `Del` (depending on manufacturer) to access boot menu
+4. Select USB drive
+5. AeThex Linux will boot directly to desktop
+
+## Configuration Files
+
+All configuration files are in `configs/`:
+
+```
+configs/
+├── grub/                      # Bootloader configuration
+│   ├── grub.cfg              # Boot menu
+│   └── themes/aethex/        # Visual theme
+├── lightdm/                  # Display manager
+│   └── lightdm.conf          # Auto-login config
+├── systemd/                  # System services
+│   ├── aethex-desktop.service    # Main desktop
+│   └── aethex-kernel.service     # OS Kernel API
+└── xsession/                 # Desktop session
+    └── aethex.desktop        # Session definition
+```
+
+## Troubleshooting
+
+### Build fails at Tauri step
+```bash
+# Install Rust dependencies for your distro
+# Ubuntu/Debian:
+sudo apt install libwebkit2gtk-4.1-dev libssl-dev libayatana-appindicator3-dev librsvg2-dev
+
+# Then retry build
+cd /workspaces/AeThex-OS
+npm run tauri:build
+```
+
+### VM won't boot
+```bash
+# Check if ISO was created successfully
+ls -lh ~/aethex-linux-build/*.iso
+
+# Verify checksum
+sha256sum -c ~/aethex-linux-build/*.sha256
+
+# Try rebuilding with clean slate
+sudo rm -rf ~/aethex-linux-build
+sudo bash script/build-linux-iso.sh
+```
+
+### Desktop doesn't auto-login
+- Default credentials: `aethex` / `aethex`
+- Check `/etc/lightdm/lightdm.conf` for auto-login settings
+- Verify service is enabled: `systemctl status lightdm`
+
+### Black screen after boot
+- Add `nomodeset` to boot parameters (press 'e' in GRUB menu)
+- Or try: `quiet splash nomodeset`
+
+## Customization
+
+### Change Default User
+Edit in `script/build-linux-iso.sh`:
+```bash
+# Replace 'aethex' with your username
+useradd -m -s /bin/bash YOUR_USERNAME
+echo 'YOUR_USERNAME:YOUR_PASSWORD' | chpasswd
+```
+
+### Add Pre-installed Software
+Add to package list in `script/build-linux-iso.sh`:
+```bash
+apt-get install -y \
+  # ... existing packages ...
+  firefox \
+  gimp \
+  vlc
+```
+
+### Change Branding
+- Logo: Replace `configs/grub/themes/aethex/logo.png`
+- Colors: Edit `configs/grub/themes/aethex/theme.txt`
+- Boot text: Edit `configs/grub/grub.cfg`
+
+## Next Steps
+
+### Distribution (Public Release)
+1. Host ISO on CDN or GitHub Releases
+2. Create installation documentation
+3. Set up update repository (apt/PPA)
+4. Add installer wizard (Calamares)
+
+### Production Hardening
+- [ ] Enable secure boot signing
+- [ ] Add encrypted home directory option
+- [ ] Configure firewall rules
+- [ ] Set up automatic security updates
+- [ ] Add AppArmor/SELinux profiles
+
+### Advanced Features
+- [ ] Live USB persistence (save data between boots)
+- [ ] Network install option (PXE boot)
+- [ ] Multi-language support
+- [ ] Custom kernel with optimizations
+- [ ] Hardware driver auto-detection
+
+## Resources
+
+- Full documentation: [AETHEX_LINUX.md](AETHEX_LINUX.md)
+- Tauri setup: [TAURI_SETUP.md](TAURI_SETUP.md)
+- Project overview: [README.md](README.md)
+
+## Support
+
+For issues or questions:
+1. Check existing documentation
+2. Review system logs: `journalctl -xe`
+3. Test in VM before real hardware
+4. File issue on GitHub repository
