+# NQRduck Module: nqrduck-autotm
+
+A module for the [nqrduck](https://github.com/nqrduck/nqrduck) project. This module is used to automatically tune and match mechanical and electrical probe coils.
+
+The module is used as a graphical user interface for the [ATM-system](https://github.com/nqrduck/ATM). The ATM-system consists of a C++ program running on the ESP32 microcontroller. The NQRduck autotm module communicates with the ESP32 microcontroller using the USB interface.
+
+For mechanically tunable probe coils stepper motors for Tuning and Matching are used. 
+For electrically tunable probe coils varactor diodes are used. The system is able to output a Tuning and Matching voltage in a range from 0 to 5V.
+
+Additionally, the system can measure the $S_{11}$ parameter of the probe coil over a frequency range.
+
+## Installation
+
+### Requirements
+Dependencies are handled via the pyproject.toml file.
+
+### Setup
+To install the module you need the NQRduck core. You can find the installation instructions for the NQRduck core [here](https://github.com/nqrduck/nqrduck).
+
+Ideally you should install the module in a virtual environment. You can create a virtual environment by running the following command in the terminal:
+```bash
+python -m venv nqrduck
+# Activate the virtual environment
+. nqrduck/bin/activate
+```
+
+You can install this module and the dependencies by running the following command in the terminal while the virtual environment is activated and you are in the root directory of this module:
+```bash
+pip install .
+```
+
+## Usage
+The module is used together with the ATM-system. Connect the ATM-system to the PC running the NQRduck program. You can connect to the ATM-system using the 'Tuning and Matching' tab in the NQRduck program.

+- b.) The 'Tuning and Matching' tab. Here you can control the ATM-system and switch between electrically and mechanically tunable probe coils.
+- c.) The '$S_{11}$' tab. Here you can measure the $S_{11}$ parameter of the probe coil over a frequency range.
+- d.) The 'Info Box'. Here you can see the current status of the ATM-system.
+- e.) The $S_{11}$ plot. Here you can see the measured $S_{11}$ parameter of the probe coil over a frequency range.
 
 ### Notes
-- The active user needs to be in the correct group to use serial ports. For example 'uucp' in Arch Linux and 'dialout' in Ubuntu.
