 ## :satellite: Usage
 
+### Common Patterns
+
+- If you don't specify a date, the method will assume you want to use the current date/time.
+- Many parameters are in shorthand - Ex: `sensor.rng`.
+- Changing a variable requires you to cast its units before using it as a parameters - Ex: `(3.14 * -1) as Radians`
+- Methods starting with 'to' change the class - Ex: `satellite.toGeodetic()` or `satellite.toITRF()`
+  - Methods that are optimized for loops are marked as `@variation optimized`
+  - Methods that are slower with expanded capabilities are marked as `@variation expanded`
+- Class parameters assume degrees and specify radians - Ex: `sensor.az` is in `degrees` and `sensor.azRad` is in `radians`.

 sensor.rae(sat, time); // Get position in range, aziimuth, elevation relative to a satellite object at the given time
 sensor.eci() // Get the sensor's position in ECI coordinates
