+# Dotfiles
+
+## Install
+
+```bash
+git clone --recurse-submodules <repo-url>
+cd new-dotfiles
+./install.sh
+```
+
+The install script detects your package manager (pacman/apt/dnf), installs dependencies, symlinks configs, and sets up `/etc/zsh/zshenv`.
+
+See [DEPENDENCIES.md](DEPENDENCIES.md) for the full package list per distro.
+
+## Structure
+
+```
+config/     → user configs, each subfolder is symlinked to ~/.config/<name>
+system/     → system-wide configs, installed with sudo
+install.sh  → package installation + symlinks + system config
+```
+
+## Adding a new config
+
+1. Copy or create the config directory under `config/`:
+   ```bash
+   cp -r ~/.config/foo config/foo
+   ```
+2. The install script's `for` loop will automatically symlink `config/foo` to `~/.config/foo` on next run.
+
+## Adding system-level config
+
+1. Place the file under `system/` with a meaningful path or name.
+2. Add an `install` line to the system config section of `install.sh`:
+   ```bash
+   sudo install -Dm644 "$DOTFILES/system/foo.conf" /etc/foo.conf
+   ```
+
+## Adding dependencies
+
+1. Add the package to the appropriate distro block in `install.sh`.
+2. Update the table in [DEPENDENCIES.md](DEPENDENCIES.md).
