 Rust based Async Executor which executes woken tasks only when it is ticked
 
+# Example
+
+```rust
+let executor = TickedAsyncExecutor::default();
+
+executor.spawn_local("MyIdentifier", async move {}).detach();
+
+// Make sure to tick your executor to run the tasks
+executor.tick(DELTA, LIMIT);
+```
+
 # Limitation
 
 - Does not work with the tokio runtime and async constructs that use the tokio runtime internally
