-## Usage
+## System Setup
 
-Configure greetd to use Moongreet:
+1. Copy configuration:
+   ```bash
+   sudo mkdir -p /etc/moongreet
+   sudo cp config/moongreet.toml /etc/moongreet/moongreet.toml
+   ```
 
-```ini
-[default_session]
-command = "moongreet"
-```
+2. Edit `/etc/moongreet/moongreet.toml` — set an absolute path for the wallpaper.
+
+3. Create cache directory:
+   ```bash
+   sudo mkdir -p /var/cache/moongreet
+   sudo chown greeter:greeter /var/cache/moongreet
+   ```
+
+4. Configure greetd (`/etc/greetd/config.toml`):
+   ```ini
+   [default_session]
+   command = "moongreet"
+   user = "greeter"
+   ```
