 If you're developing a plugin that has a user interface, take a look at our https://elastic.github.io/eui[Elastic UI Framework].
 It documents the CSS and React components we use to build Kibana's user interface.

+==== TypeScript Support
+Plugin code can be written in http://www.typescriptlang.org/[TypeScript] if desired. To enable TypeScript support create a `tsconfig.json` file at the root of your plugin that looks something like this:
+
+["source","js"]
+-----------
+{
+  // extend Kibana's tsconfig, or use your own settings
+  "extends": "../../kibana/tsconfig.json",
+
+  // tell the TypeScript compiler where to find your source files
+  "include": [
+    "server/**/*",
+    "public/**/*"
+  ]
+}
+-----------
+
+TypeScript code is automatically converted into JavaScript during development, but not in the distributable version of Kibana. If you use the {repo}blob/{branch}/packages/kbn-plugin-helpers[@kbn/plugin-helpers] to build your plugin then your `.ts` and `.tsx` files will be permanently transpiled before your plugin is archived. If you have your own build process, make sure to run the TypeScript compiler on your source files and ship the compilation output so that your plugin will work with the distributable version of Kibana.
