+## Executor
 
-The `embassy::executor` module provides an async/await executor based on [static-executor](https://github.com/Dirbaio/static-executor).
+The `embassy::executor` module provides an async/await executor designed for embedded usage.
 
 - No `alloc`, no heap needed. Task futures are statically allocated.
-- Integrated timer queue allows simple sleeping: `Timer::after(Duration::from_ticks(64000)).await;`.
-- Suitable for low-power operation. Using interrupts or `WFE/SEV` ensures the CPU sleeps when there's no work to do. No busy-loop polling.
+- No "fixed capacity" data structures, executor works with 1 or 1000 tasks without needing config/tuning.
+- Integrated timer queue: sleeping is easy, just do `Timer::after(Duration::from_secs(1)).await;`.
+- No busy-loop polling: CPU sleeps when there's no work to do, using interrupts or `WFE/SEV`.
+- Efficient polling: a wake will only poll the woken task, not all of them.
+- Fair: a task can't monopolize CPU time even if it's constantly being woken. All other tasks get a chance to run before a given task gets polled for the second time.
 - Creating multiple executor instances is supported, to run tasks with multiple priority levels. This allows higher-priority tasks to preempt lower-priority tasks.
-- Compatible with RTIC (example coming soon).
