+
+This library is a utility for use by Slack's next-generation application
+platform, focused on remixable units of functionality encapsulated as ephemeral
+functions. It implements the rules for communication (i.e. the protocol) between
+[Slack CLI][cli] and any Slack app development SDKs.
+
+This is separate from the [deno-slack-hooks][hooks] project, which implements
+the various APIs encapsulating work delegation from the CLI to the SDK. The
+[deno-slack-hooks][hooks] project implements the API, which uses this library
+under the hood.
+
+## Requirements
+
+This library requires a recent (at least 1.22) version of
+[deno](https://deno.land).
+
