 #### Timers
 
-* A timer is represented by normal `asyncio.sleep()`
+* A timer is represented by normal `asyncio.sleep()` or a `workflow.sleep()` call
 * Timers are also implicitly started on any `asyncio` calls with timeouts (e.g. `asyncio.wait_for`)
 * Timers are Temporal server timers, not local ones, so sub-second resolution rarely has value
 * Calls that use a specific point in time, e.g. `call_at` or `timeout_at`, should be based on the current loop time
