-# Yew Trunk Template

-This is a fairly minimal template for a Yew app that's built with [Trunk].
+This was generated according to the getting started instructions of [yew](https://yew.rs/)
+and then enriched with Bazel build rules.
 
-## Usage
+## Bazel
 
-For a more thorough explanation of Trunk and its features, please head over to the [repository][trunk].
+Build and serve the UI with:
+
+```bash
+bazel run //serve
+```
+
+This also builds a small rust server application to serve the files.
