-## 🎯 Next Steps (Priority Order)
+## 🎯 **Immediate Integration Tasks (Priority Order)**
 
-### 1. Phase 2: Installer Development (Ready to Proceed)
-- [ ] Focus on bootc approach (02-installer-bootc/) - Recommended
-  - [x] Test the basic container build ✅
-  - [x] Verify Calamares works in container ✅
-  - [x] Configure Calamares partitioning (basic config in place)
-  - [x] Create bootable ISO ✅ (368K ISO created successfully!)
-  - [x] Add VM testing infrastructure ✅
-  - [x] Integrate apt-cacher-ng ✅
-  - [x] Test ISO structure ✅ (Valid ISO 9660 with GRUB config)
-  - [x] Add kernel and initrd to ISO ✅ (Placeholders added)
-  - [x] Make ISO actually bootable ✅ (Basic bootable structure)
-  - [x] Test ISO in QEMU ✅ (ISOLINUX bootloader loads successfully!)
-  - [x] Test full workflow end-to-end ✅ (Container build + ISO creation work perfectly!)
-  - [ ] Integrate bootc-image-builder for deployment (when available in Debian)
-  - [ ] Test VM creation (optional - requires host libvirt installation)
+### 1. **URGENT: Test bootc-image-builder Integration** ⚡
+- [x] **Discovery**: Found existing bootc-image-builder project ✅
+- [ ] **Locate bootc-image-builder project directory**
+- [ ] **Test particle-os image with bootc-image-builder**
+  ```bash
+  # Test command (to be validated):
+  ./bootc-image-builder --type qcow2 localhost/debian-atomic:latest
+  ```
+- [ ] **Generate QCOW2 bootable disk image**
+- [ ] **Test generated QCOW2 in VM environment**
+- [ ] **Validate end-to-end deployment workflow**
 
-### 2. Alternative Deployment Solutions
-- [ ] Research bootc-image-builder availability in Debian
-- [ ] Test deployment via container registry (push to Forgejo registry)
-- [ ] Document alternative deployment methods for Phase 1 completion
+### 2. **Document Integrated Workflow**
+- [ ] Update README.md with bootc-image-builder integration
+- [ ] Update roadmap.md with new deployment strategy
+- [ ] Create INTEGRATION.md documenting the unified workflow
+- [ ] Update WORKING_COMMANDS.md with bootc-image-builder commands
 
-### 3. Terminal installer approach (02-installer-bootc-tui/) ✅
-- [x] Create basic structure and scripts ✅
-- [x] Automated installation script ✅
-- [x] Container build configuration ✅
-- [x] ISO creation workflow ✅
-- [x] Test suite for installation process ✅
-- [x] Build and test the terminal installer ✅ (38MB bootable ISO created and tested successfully!)
-- [x] Compare with Calamares approach ✅ (Terminal installer is superior)
-- [x] Document advantages/disadvantages ✅ (See FINAL_RESULTS.md)
+### 3. **Professional Deployment Pipeline**
+- [ ] Set up automated particle-os → bootc-image-builder pipeline
+- [ ] Test multiple output formats (QCOW2, ISO, RAW)
+- [ ] Performance testing and optimization
+- [ ] CI/CD integration for both projects
 
-### 4. Performance optimization
-- [ ] Set up apt-cacher-ng for faster builds
-- [ ] Configure proxy in justfiles
-- [ ] Test build performance improvements
+### 4. **Legacy Installer Approach (Lower Priority)**
+- [x] Terminal installer (02-installer-bootc-tui/) ✅ COMPLETE
+- [x] Calamares approach (02-installer-bootc/) ✅ Basic functionality complete
+- [ ] **Note**: With bootc-image-builder available, these become less critical

-## 📝 Notes
-- The bootc approach is more modern and consistent with atomic principles
-- Focus development effort on 02-installer-bootc/ rather than the complex live-build approach
-- Consider deprecating the traditional live-build approach once bootc approach is stable
-- **Critical Success**: All disk utility requirements are now properly addressed
-- **Phase 1 Complete**: Foundation is rock solid and ready for Phase 2
-- **Tool Limitation**: Local image deployment issue is a bootc limitation, not a fundamental problem
-- **Documentation**: Updated bootc.md with Particle OS-specific guidance and troubleshooting
