 # SawLFO
 
-Produces a sawtooth LFO, with output ranging from min to max.

-Signature:
 ```python
 SawLFO(frequency=1.0, min=0.0, max=1.0, phase=0.0)
 ```

+Produces a sawtooth LFO at the fiven `frequency` and `phase` offset, with output ranging from `min` to `max`.
+
+### Examples
+
+```python
+
+# Siren effect, using a sawtooth LFO to modulate a sine wave's frequency
+lfo = SawLFO(1, 200, 1000)
+sine = SineOscillator(lfo)
+sine.play()
