 The `smartmeter-datacollector` tool is a Python3 software which allows you to continuously retrieve data from supported smart meters (listed below).
 The acquired values can be forwarded to one or more data sinks like a MQTT broker or logger.
 
+This tool is an open source software funded by **[EKZ (Elektrizitätswerke des Kantons Zürich)](https://www.ekz.ch)** and developed by **[Supercomputing Systems AG](https://www.scs.ch)**. The goal of this voluntary initiative is to create a tool that can read, decode and decrypt data (if necessary) from the local interface of various smart meters and convert it into human-readable and simple formats. This should eliminate the complexity of decoding DLMS and similar protocols for the user. The user has the data in a format, which he can easily use in various use-cases ranging from simple vizualization (see [Method 1: Raspberry Pi image with demo](#method-1-raspberry-pi-image-with-demo)) to integration into energy management algorithms or into custom home automation software.

 The following smart meters are supported:
