+
+## Key Changes from Original Configuration
+
+### ✅ Removed
+- **nix-darwin** input and outputs
+- **macOS/Darwin** conditionals (lines 54-58 in sh.nix)
+- **WSL** hard-coded paths (lines 31-32 in tmux.nix)
+- **Windows** checks (lines 115-117 in sh.nix)
+
+### ✅ Added
+- **System-level configuration** (configuration.nix)
+  - Boot loader setup (systemd-boot)
+  - Networking with NetworkManager
+  - User account definition
+  - System timezone and locale
+  - Nix flakes enabled
+
+- **Hardware configuration template** (hardware-configuration.nix)
+  - Placeholder for NixOS-generated config
+  - Must be replaced during installation
+
+### ✅ Modified
+- **Home Manager integration**
+  - Now runs as NixOS module (not standalone)
+  - useGlobalPkgs enabled
+  - Removed allowUnfree (handled at system level)
+
+- **Shell configuration** (modules/sh.nix)
+  - Removed all platform-specific conditionals
+  - Clean Linux-only configuration
+  - Added `profileExtra` for .profile sourcing
+
+- **Tmux configuration** (modules/tmux.nix)
+  - Commented out note keybindings (C-n, C-p)
+  - Paths need to be updated for NixOS environment
+
+- **Development tools** (modules/dev.nix)
+  - Custom packages commented out:
+    - claude-code
+    - opencode
+    - gemini-cli
+  - TODO notes added for integration
+
+## Validation Status
+
+✅ Flake syntax is valid
+✅ Configuration evaluates successfully
+✅ All module imports resolve correctly
+✅ No blocking errors found
+
+⚠️ Requires `--impure` flag due to NIX_LD settings
+
+## What Needs to Be Done Before Use
+
+### 🔴 Critical (Must Do)
+1. **Replace hardware-configuration.nix**
+   ```bash
+   sudo nixos-generate-config --show-hardware-config > nixos/hardware-configuration.nix
+   ```
+
+2. **Update hostname** in configuration.nix
+   - Currently set to: "nixos"
+   - Change to your actual hostname
+
+3. **Verify boot loader** choice in configuration.nix
+   - UEFI: systemd-boot (currently enabled)
+   - BIOS: GRUB (commented out)
+
+### 🟡 Important (Should Do)
+1. **Verify timezone** in configuration.nix
+   - Currently: "Europe/Berlin"
+
+2. **Check locale settings** in configuration.nix
+   - Currently: en_US.UTF-8 / de_DE.UTF-8
+
+3. **Verify nvim lua files** exist at:
+   - `/home/pan/dev/config/dot/nvim/base.lua`
+   - `/home/pan/dev/config/dot/nvim/keymaps.lua`
+   - `/home/pan/dev/config/dot/nvim/plugins.lua`
+   - `/home/pan/dev/config/dot/nvim/filetype.lua`
+
+### 🟢 Optional (Nice to Have)
+1. **Update tmux note paths** in modules/tmux.nix (C-n, C-p keybindings)
+2. **Add custom packages** (claude-code, opencode, gemini-cli)
+3. **Review and customize** any other settings
+
+## How to Apply
+
+### Test Build (Recommended First)
+```bash
+cd /home/pan/dev/config/dot/nix/nixos
+sudo nixos-rebuild build --flake .#nixos --impure
+```
+
+### Apply Configuration
+```bash
+cd /home/pan/dev/config/dot/nix/nixos
+sudo nixos-rebuild switch --flake .#nixos --impure
+```
+
+### Update Packages
+```bash
+nix flake update
+sudo nixos-rebuild switch --flake .#nixos --impure
+```
+
+## Verification Checklist
+
+After applying the configuration, verify:
+
+- [ ] System boots successfully
+- [ ] User 'pan' can login
+- [ ] Zsh loads with Prezto theme
+- [ ] fzf keybindings work (Ctrl+R)
+- [ ] zoxide works (`cd` command)
+- [ ] Tmux starts without errors
+- [ ] Neovim opens with all plugins
+- [ ] Git config shows correct user
+- [ ] Lazygit and Jujutsu work
+- [ ] Taskwarrior shows version 3.x
+- [ ] Direnv loads .envrc files
+
+## Files Preserved
+
+The original Home Manager configuration remains untouched:
+- `/home/pan/dev/config/dot/nix/flake.nix`
+- `/home/pan/dev/config/dot/nix/common.nix`
+- `/home/pan/dev/config/dot/nix/user/*`
+
+You can continue using the Ubuntu setup alongside this NixOS configuration.
+
+## Documentation
+
+- **README.md**: Complete installation and usage guide
+- **TODO.md**: Detailed list of remaining tasks and known issues
+- **SUMMARY.md**: This file - quick overview and status
+
+## Support
+
+For issues or questions:
+1. Check TODO.md for known issues
+2. Review README.md for troubleshooting
+3. Consult NixOS manual: https://nixos.org/manual/nixos/stable/
+
+## Next Steps
+
+1. ✅ Configuration created successfully
+2. ⏳ Replace hardware-configuration.nix
+3. ⏳ Update hostname and timezone
+4. ⏳ Test build configuration
+5. ⏳ Apply configuration
+6. ⏳ Verify all components work
+
+Good luck with your NixOS migration! 🚀
