  * Channel with array buffer of a fixed [capacity].
  * Sender suspends only when buffer is fully and receiver suspends only when buffer is empty.
  *
+ * This channel is created by `Channel(capacity)` factory function invocation.
+ *
  * This implementation uses lock to protect the buffer, which is held only during very short buffer-update operations.
  * The lists of suspended senders or receivers are lock-free.
