+## Web installer
+
+**BETA**: You can now install the BTClock firmware directly from your browser (only Chrome/Chromium and Microsoft Edge for now) using https://dsbaars.github.io/btclock-esp-web/
+
+## Build and compile
+
 To do this we need [Visual Studio Code](https://code.visualstudio.com/Download), [node.js](https://nodejs.org/en/download) and [yarn](https://classic.yarnpkg.com/lang/en/docs/install/#windows-stable). 
 
 Also you will need the [PlatformIO IDE for Visual Studio Code](https://platformio.org/install/ide?install=vscode)
