+## Description
+The pyhoff package allows you to read and write the most common
+Beckhoff and WAGO bus terminals ("Busklemmen") using the Ethernet bus
+coupler ("Busskoppler") BK9000, BK9050, BK9100, or WAGO 750_352
 over Ethernet TCP/IP based on ModBus TCP.
 
-It depends on the package pyModbusTCP. This can be installed with:
+### Key Features
+- Supports a wide range of Beckhoff and WAGO analog and digital bus
+  terminals.
+- Very light weight: no dependencies; compact code base
+- Easy to extend
+- Using standardized ModBus TCP.
+- Provides high-level abstractions for reading and writing data
+  from/to IO-terminals with minimal code
 
-    pip install pyModbusTCP
+### Usage Scenarios
+- Industrial test setups.
+- Research automation setups.
+- Data acquisition and monitoring.
 
+## Installation
+The package has no additional decencies. It can be installed with pip:
+
+```bash
+pip install pyhoff
+```
+
+## Usage
 It is easy to use as the following example code shows:
 
 ```python
-from pyhoff import *
+from pyhoff.devices import *
 
 # connect to the BK9050 by tcp/ip on default port 502
-bus_coupler = ModBusBK9050("172.16.17.1")
+bus_coupler = BK9050("172.16.17.1")
 
 # list of all bus terminals connected to the bus coupler
 # in the order of the physical arrangement

-The following terminals are implemented:
-- KL1104: 4x digital input 24 V
-- KL2404: 4x digital output with 500 mA
-- KL2424: 4x digital output with 2000 mA
-- KL3054: 4x analog input 4...20 mA 12 Bit single-ended
-- KL3202: 2x analog input PT100 16 Bit 3-wire
-- KL3214: 4x analog input PT100 16 Bit 3-wire
-- KL4002: 2x analog output 0...10 V 12 Bit differentiell
-- KL4004: 4x analog output 0...10 V 12 Bit differentiell
-- Dummy terminals without io functionality: KL9100, KL9183, KL9188

+## Developer Guide
+To get started with developing the `pyhoff` package, follow these steps:
+
+1. **Clone the Repository**
+   First, clone the repository to your local machine using Git:
+
+   ```bash
+   git clone https://github.com/Nonannet/pyhoff.git
+   cd pyhoff
+   ```
+
+2. **Set Up a Virtual Environment**
+   It is recommended to use a virtual environment to manage dependencies. You can create one using `venv`:
+
+   ```bash
+   python -m venv venv
+   source venv/bin/activate  # On Windows use `venv\Scripts\activate`
+   ```
+
+3. **Install Dev Dependencies**
+   Install the dependencies required for development using `pip`:
+
+   ```bash
+   pip install -r requirements-dev.txt
+   ```
+
+4. **Run Tests**
+   Ensure that everything is set up correctly by running the tests:
+
+   ```bash
+   pytest
+   ```
