+#### Using POCS
+
+POCS provides a command line interface for all operations. After installation:
+
+**1. Configure your unit (required first step):**
+```bash
+pocs config setup
+```
+
+**2. Run automated observing:**
+```bash
+pocs run auto
+```
+
+**3. Manual hardware control:**
+```bash
+# Mount control
+pocs mount slew-to-target --target M42
+pocs mount park
+
+# Camera testing
+pocs camera take-pics --num-images 5 --exptime 2.0
+```
+
+For more CLI commands, run `pocs --help` or see the beginner documentation above.
