+## Configuration
+
+Linutil supports configuration through a TOML config file. Path to the file can be specified with `--config` (or `-c`).
+
+Available options:
+- `auto_execute` - a list of commands to execute automatically (can be combined with `--skip-confirmation`)
+
+Example config:
+```toml
+# example_config.toml
+
+auto_execute = [
+    "Fastfetch",
+    "Alacritty",
+    "Kitty"
+]
+```
+
+```bash
+linutil --config /path/to/example_config.toml
+```
