 ```
 
 ## Usage
 
+This module implements async thermostat logic but does not include any hardware-specific code.
+
+Setup generally involves:
+
+1. Initialize a `Thermostat` instance and set the mode and setpoint(s)
+1. Write a polling loop or other function to read temperature from a sensor
+1. Call `set_temp()` to update with the temperature read from the sensor
+1. Check or `await` the `heating` and `cooling` flags (`asyncio.Event` objects)
+1. Use the flags to control relays or other hardware as needed
+
+### Example

 ```python
 from thermostat import Thermostat

+## Releasing
+
+To release a new version, first cross-compile to micropython bytecode. You need `mpy-cross` in your `PATH`:
+
+```bash
+mpy-cross thermostat/__init__.py
