# Deno Language Server The Deno Language Server provides a server implementation of the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) which is specifically tailored to provide a _Deno_ view of code. It is integrated into the command line and can be started via the `lsp` sub-command. > :warning: The Language Server is highly experimental and far from feature > complete. This document gives an overview of the structure of the language > server. ## Structure 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.
