+Because we recognize that not every TypeScript/JavaScript project that you might
+work on in VSCode. Therefore by default, this extension will only apply the Deno
+language server when the setting `deno.enable` is set to `true`. This can be
+done via editing the settings or using the command _Deno: Initialize Workspace
+Configuration_.
+
+While you can enable Deno globally, you probably only want to do that if every
+JavaScript/TypeScript workspace you work on in VSCode is a Deno based one.
+
+## Commands
+
+The extension provides several commands:
+
+- _Deno: Cache_ - instructs Deno to fetch and cache all the dependencies of the
+  current file open in the editor. This is similar to doing `deno cache` on the
+  command line. Deno will not automatically fetch and cache remote dependencies.
+
+  > ℹ️ &nbsp; If there are missing dependencies in a module, the extension will
+  > provide a quick fix to fetch and cache those dependencies, which invokes
+  > this command for you.
+- _Deno: Initialize Workspace Configuration_ - will enabled Deno on the current
+  workspace and allow you to choose to enable linting and Deno _unstable_ API
+  options.
+- _Deno: Language Server Status_ - displays a page of information about the
+  status of the Deno Language Server. Useful when submitting a bug about the
+  extension or the language server.
+- _Deno: Welcome_ - displays the information document that appears when the
+  extension is first installed.
+
+## Formatting
+
+The extension provides formatting capabilities for JavaScript, TypeScript, JSX,
+and TSX documents. When choosing to format a document or setting up a default
+formatter for these type of files, the extension should be listed as an option.
