+
+`custom-elements-languageserver` depends on `typescript`. Both packages can be installed via `npm`:
+```sh
+npm install -g typescript custom-elements-languageserver
+```
+To configure typescript language server, add a
+[`tsconfig.json`](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) or
+[`jsconfig.json`](https://code.visualstudio.com/docs/languages/jsconfig) to the root of your
+project.
+Here's an example that disables type checking in JavaScript files.
+```json
+{
+  "compilerOptions": {
+    "module": "commonjs",
+    "target": "es6",
+    "checkJs": false
+  },
+  "exclude": [
+    "node_modules"
+  ]
+}
+
+The best way to utilize the Custom Elements Language Server is to enable the [Custom Elements Manifest](https://github.com/webcomponents/custom-elements-manifest)(CEM) in your project by installing
+a CEM generator like one provided by [The Open WC Team](https://github.com/open-wc/custom-elements-manifest/tree/master/packages/analyzer).
+
+Generating a CEM in watch mode will provide you with the best user experience. If your dependencies ship with a Custom Elements Manifest, those will be utilized also.
+
+```
+
+
+
+**Snippet to enable the language server:**
+```lua
+require'lspconfig'.custom_elements_ls.setup{}
+```
+
+
+**Default values:**
+  - `cmd` : 
+  ```lua
+  { "custom-elements-languageserver", "--stdio" }
+  ```
+  - `filetypes` : 
+  ```lua
+  { "javascript", "javascriptreact", "javascript.jsx", "typescript", "typescriptreact", "typescript.tsx", "html" }
+  ```
+  - `init_options` : 
+  ```lua
+  {
+    hostInfo = "neovim"
+  }
+  ```
+  - `root_dir` : 
+  ```lua
+  root_pattern("package.json", "tsconfig.json", "jsconfig.json", ".git")
+  ```
