-# Introduction
+# Introduction
+
+During my training, I came into contact with the Modbus protocol.
+The implementation I developed at that time was very cumbersome and rigid.
+There were huge inheritance hierarchies and the design was very confusing.
+
+In 2018, I wanted to do better and completely redesigned the library.
+After changing companies, this library could be integrated and tested under real-world conditions.
+This quickly led to new challenges and some specific requirements were implemented.
+This was the first time that both TCP and the RTU protocol were fully implemented.
+
+However, the structure of the library also revealed problems and was too rigid for the requirements.
+Therefore, in 2024, there was a new development from scratch, which now exists and has already been tested by some eager people – THANK YOU SO MUCH!
+
+The focus is, of course, on the development of the protocol and the clients. However, a server implementation (TCP/RTU) is also available.
+
+For detailed changes of the current development, see the [CHANGELOG].
