\ No newline at end of file
+A prototype of an energy dashboard for the Bosch Schwieberdingen facility. The development of this dashboard was carried out as part of sub-project 3.1 (_Effizienzsteigerung durch intelligente Vernetzung von Erzeugern und Verbrauchern in Gewerbegebieten am Beispiel der Robert Bosch GmbH, Standort Schwieberdingen_) of the iCity project.
+
+## Features
+
+- Retrieve raw observations at 15 minute and 60 minute sampling rates
+
+- Aggregate the raw observations for daily or monthly intervals. The currently available aggregation options are `sum`, `maximum`, `minimum` and `average`
+
+- Visualize the raw and aggregated observations using four types of charts: line, heatmap, scatter plot and column. These charts are based on the [Highcharts](https://www.highcharts.com/blog/products/highcharts/) JavaScript library
+
+## Installation
+
+- Clone this repository
+
+- Create a `config.mjs` file and place it in the root of the `public/js` directory. This file should have the following structure:
+
+```javascript
+const CESIUM_ION_ACCESS_TOKEN = "your_cesium_ion_token";
+const SENSORTHINGS_API_BASE_URL = "your_sensorthingsapi_server_url";
+export { CESIUM_ION_ACCESS_TOKEN, SENSORTHINGS_API_BASE_URL };
+```
+
+- Install the application's dependencies
+
+```bash
+$ npm i
+```
+
+- Start the application (which should be available at `http://localhost:3000`)
+
+```bash
+$ nodemon index.js
