 ## Highlights
 
+### Read & Write
+
+*With optional concurrency levels.*
+
+* Reading all entries in a channel.
+* Writing all entries from a source to a channel.
+* Piping (consuming) all entries to a buffer (channel).
+* `.AsAsyncEnumerable()` (`IAsyncEnumerable`) support for .NET Standard 2.1+ and .NET Core 3+
+
+### Special `ChannelReader` Operations
+
+* `Filter`
+* `Transform`
+* `Batch`
+* `Join`
