 🇩🇪Heißkleber _m_: "hot glue".
 
-Heisskleber is a versatile library designed to seamlessly "glue" together various data producers and consumers across a multitude of protocols including zmq, mqtt, udp, serial, influxdb, and cmdline. With the ambition to extend into REST API interactions and file operations, Heisskleber offers both synchronous and asynchronous interfaces to cater to a wide range of IoT connectivity needs.

+data producers and consumers across a multitude of protocols
+including **zmq**, **mqtt**, **udp**, **serial**, **files** and **cmdline**.
+Heisskleber offers asynchronous interfaces for a wide range of IoT connectivity needs.
 
 ## Features
 
-- Multiple Protocol Support: Easy integration with zmq, mqtt, udp, serial, and cmdline. Future plans include REST API and file operations.
-- Custom Data Handling: Customizable "unpacker" and "packer" functions allow for the translation of any data format (e.g., ascii encoded, comma-separated messages from a serial bus) into dictionaries for easy manipulation and transmission.
