+There are several commands that might be issued by the language server to the
+client, which the client is expected to implement:
+
+- `deno.cache` - This is sent as a resolution code action when there is an
+  un-cached module specifier that is being imported into a module. It will be
+  sent with and argument that contains the resolved specifier as a string to be
+  cached.
+- `deno.showReferences` - This is sent as the command on some code lenses to
+  show locations of references. The arguments contain the specifier that is the
+  subject of the command, the start position of the target and the locations of
+  the references to show.
+- `deno.test` - This is sent as part of a test code lens to, of which the client
+  is expected to run a test based on the arguments, which are the specifier the
+  test is contained in and the name of the test to filter the tests on.
