 ## Installation
 
-1. Copy all `.cfg` files to your Klipper config directory
-2. Add `[include calibration/*.cfg]` to your `printer.cfg`
-3. Restart Klipper
-4. Run `CALIBRATION_MENU` to start
+### Option A: Via user_settings.cfg (Recommended)
+
+1. **Clone repo to config directory:**
+   ```bash
+   cd ~/printer_data/config
+   git clone https://git.sky-net.it/nocci/open4neptune-new.git
+   ```
+
+2. **Copy calibration folder:**
+   ```bash
+   cp -r open4neptune-new/calibration/ ~/printer_data/config/
+   ```
+
+3. **The include is already in optimized_user_settings.cfg:**
+   ```ini
+   [include calibration/*.cfg]
+   ```
+
+4. **Restart Klipper**
+
+### Option B: Direct include in printer.cfg
+
+1. **Copy calibration folder** to `~/printer_data/config/calibration/`
+
+2. **Add to printer.cfg** (at the end, after other includes):
+   ```ini
+   [include calibration/*.cfg]
+   ```
+
+3. **Restart Klipper**
+
+### Test Installation
+
+```gcode
+; In Mainsail/Fluidd Console:
+CALIBRATION_MENU
+```
