          ## Requirements

          - Wayland compositor (niri or Hyprland recommended)
          - Quickshell framework
          - Qt6

          ## Installation Steps

          1. **Install quickshell assets:**
             ```bash
             mkdir -p ~/.config/quickshell
             cp -r dms ~/.config/quickshell/
             ```

          2. **Install the DMS CLI binaries:**
             ```bash
             sudo install -m 755 bin/dms /usr/local/bin/dms
             ```

          3. **Install shell completions (optional):**
             ```bash
             # Bash
             sudo install -m 644 completions/completion.bash /usr/share/bash-completion/completions/dms

             # Fish
             sudo install -m 644 completions/completion.fish /usr/share/fish/vendor_completions.d/dms.fish

             # Zsh
             sudo install -m 644 completions/completion.zsh /usr/share/zsh/site-functions/_dms
             ```

          4. **Start the shell:**
             ```bash
             dms run
             ```

          ## Configuration

          - Settings are stored in `~/.config/DankMaterialShell/settings.json`
          - Plugins go in `~/.config/DankMaterialShell/plugins/`
          - See the documentation in the `dms/` directory for more details

          ## Troubleshooting

          - Run with verbose output: `quickshell -v -p ~/.config/quickshell/dms`
          - Check logs in `~/.local/state/DankMaterialShell/`
          - Ensure all dependencies are installed
