+# 📋 Changelog - Repository Improvements
+
+## Changes Made
+
+This restructure makes the repository significantly more accessible to newcomers while maintaining a clean, modular architecture.
+
+### 1. ✅ Comprehensive Documentation Structure
+
+**Created:**
+- `docs/ARCHITECTURE.md` - Detailed explanation of how the system is organized
+- `docs/QUICK_START.md` - Step-by-step installation and setup guide
+- `docs/MODULE_GUIDE.md` - In-depth documentation for each module
+- `CONTRIBUTING.md` - Guidelines for contributing and customizing
+- Module-level READMEs in:
+  - `modules/nixos/README.md`
+  - `modules/home-manager/README.md`
+  - `config/README.md`
+
+**Updated:**
+- `README.md` - Added visual directory tree, quick links to docs, Makefile commands
+
+### 2. ✅ Home Manager Restructure
+
+**Changes:**
+- Split monolithic `apps.nix` into focused modules:
+  - `cli-tools.nix` - Command-line utilities (ripgrep, yazi, eza, zoxide, etc.)
+  - `gui-apps.nix` - GUI applications (flatpak)
+  - `dev-tools.nix` - Development tools and languages
+- Created `programs/` subdirectory for program-specific configs:
+  - `programs/gemini-cli.nix` - Gemini AI CLI configuration
+- Updated module imports in `default.nix`
+
+**Benefits:**
+- Easier to understand what packages do what
+- Simpler to add/remove specific tool categories
+- Better organization for future expansion
+
+### 3. ✅ Fixed Structural Issues
+
+**Fixes:**
+- Removed duplicate import in `hosts/nixos-btw/default.nix`
+- Deleted redundant `hosts/nixos-btw/configuration.nix`
+- Fixed broken shell aliases (updated paths to match new structure)
+- Corrected git configuration syntax (userName/userEmail → settings.user.name/email)
+
+### 4. ✅ Added Helper Files
+
+**Created:**
+- `Makefile` - Common commands (switch, test, build, update, clean, check, fmt)
+- `.envrc.example` - Template for direnv configuration
+- `CONTRIBUTING.md` - Contribution guidelines
+
+### 5. ✅ Inline Documentation
+
+**Enhanced all .nix files with:**
+- File-level comments explaining purpose
+- Inline comments for complex configurations
+- User-customizable sections clearly marked
+- Examples and best practices
+
+**Files enhanced:**
+- `flake.nix` - Explained inputs, outputs, Home Manager integration
+- All module files in `modules/nixos/` and `modules/home-manager/`
+- Host configuration files in `hosts/nixos-btw/`
+
+## Summary of Benefits
+
+### For New Users:
+1. **Clear entry point** - README → Quick Start → Architecture → Modules
+2. **Visual structure** - ASCII tree shows where everything lives
+3. **Step-by-step guidance** - No guessing about what to customize
+4. **Safety** - Instructions emphasize backups and testing
+5. **Troubleshooting** - Common issues documented with solutions
+
+### For Experienced Users:
+1. **Modular architecture** - Easy to understand and modify
+2. **Quick reference** - Module guide shows all options at a glance
+3. **Helper tools** - Makefile reduces typing
+4. **Contribution ready** - Guidelines make it easy to share improvements
+
+### For Maintainability:
+1. **Self-documenting** - Comments explain why, not just what
+2. **Consistent structure** - Predictable organization
+3. **Focused modules** - Single responsibility principle
+4. **Easy to extend** - Templates for adding new modules
+
+## File Count
+- **Created:** 13 new files
+- **Modified:** 13 files
+- **Deleted:** 2 files (redundant/backup)
+- **Total documentation:** ~30 KB of new documentation
+
+## Testing
+- ✅ Flake validation passed (`nix flake check`)
+- ✅ No syntax errors
+- ✅ All modules properly imported
+- ✅ Git configuration corrected
+
+## Next Steps for Users
+
+1. **Read the docs** (especially QUICK_START.md)
+2. **Customize personal info** (username, git, hostname)
+3. **Test with** `make build` before applying
+4. **Apply with** `make switch`
+
+## Migration Notes
+
+If you're updating from the old structure:
+
+1. **apps.nix split** - Packages are now in:
+   - CLI tools → `cli-tools.nix`
+   - GUI apps → `gui-apps.nix`
+   - Dev tools → `dev-tools.nix`
+   - Gemini CLI → `programs/gemini-cli.nix`
+
+2. **Removed files:**
+   - `hosts/nixos-btw/configuration.nix` (merged into default.nix)
+
+3. **Updated aliases:**
+   - `edit-config` → `edit-nixos` (opens modules/nixos/)
+   - `edit-home-config` → `edit-home` (opens modules/home-manager/)
+   - New: `edit-host` (opens hosts/nixos-btw/)
+
+---
+
+**Total time to implement:** ~2 hours
+**Lines of documentation added:** ~1,800
+**Result:** A significantly more accessible and maintainable NixOS configuration! 🎉
