+## About
+
+This is the official Wails Vue template.
+
+You can configure the project by editing `wails.json`. More information about the project settings can be found
+here: https://wails.io/docs/reference/project-config
+
+## Live Development
+
+To run in live development mode, run `wails dev` in the project directory. This will run a Vite development
+server that will provide very fast hot reload of your frontend changes. If you want to develop in a browser
+and have access to your Go methods, there is also a dev server that runs on http://localhost:34115. Connect
+to this in your browser, and you can call your Go code from devtools.
+
+## Building
+
+To build a redistributable, production mode package, use `wails build`.
