 When the language server is started, a `LanguageServer` instance is created
 which holds all of the state of the language server. It also defines all of the
 methods that the client calls via the Language Server RPC protocol.

+## Custom requests
+
+The LSP currently supports the following custom requests. A client should
+implement these in order to have a fully functioning client that integrates well
+with Deno:
+
+- `deno/cache` - This command will instruct Deno to attempt to cache a module
+  and all of its dependencies. It expects an argument of
+  `{ textDocument: TextDocumentIdentifier }` to be passed.
+- `deno/performance` - Requests the return of the timing averages for the
+  internal instrumentation of Deno.
+- `deno/virtualTextDocument` - Requests a virtual text document from the LSP,
+  which is a read only document that can be displayed in the client. This allows
+  clients to access documents in the Deno cache, like remote modules and
+  TypeScript library files built into Deno. It also supports a special URL of
+  `deno:/status.md` which provides a markdown formatted text document that
+  contains details about the status of the LSP for display to a user.
