+# Hyprland Monitors
+
+A Vicinae extension for managing monitor configurations in Hyprland. Easily adjust monitor settings including resolution, refresh rate, scaling, rotation, and positioning.
+
+## Features
+
+- **Resolution & Refresh Rate**: Change resolution and refresh rate from available modes
+- **Display Scaling**: Adjust UI scaling
+- **Monitor Rotation**: Rotate displays
+- **Positioning**: Position monitors relative to each other (Primary, Left, Right, Above, Below)
+
+
+## Commands
+
+- **Monitor Settings**: Opens monitor settings and lets you configure displays
+- **Configure active monitor**: Opens the active monitor configuration flow directly
+
+
+## Persisted Configuration
+
+Persisted configuration is optional. By default, changes are not persisted. Enable persisted mode with the **Persist Changes** preference.
+
+The extension uses the following preferences:
+
+### Persist Changes
+Default: `false`
+
+When enabled, monitor changes are written to `vicinae-monitors.conf` and reused. When disabled (default), changes are applied without persisting monitor rules.
+
+### Hyprland Config Path
+Default: `~/.config/hypr/hyprland.conf`
+
+Path to your main Hyprland configuration file. The extension will automatically add a source line to include the Vicinae monitors configuration.
+
+### Vicinae Monitors Config Path
+Default: `~/.config/hypr`
+
+Directory where the extension will store the `vicinae-monitors.conf` file containing your monitor rules.
+
+## Requirements
+
+- Hyprland window manager must be installed and running
+
+## Development
