+# rpi_dht_modbus - Simple server to provide Modbus TCP access to DHT sensor series.
+
+## Introduction
+
+This is a combination of [Adafruit DHT library](https://github.com/adafruit/Adafruit_Python_DHT) and
+[pymodbus](https://github.com/riptideio/pymodbus) Modbus stack.
+
+The server runs as a Modbus TCP server and gives access to DHT sensors value via Modbus registers.
+
+## Installation
+
+You will need Python version 3 (tested on RPi model B with Python 3.5) with `virtualenv` module.
+After repository cloning run:
+```
+virtualenv venv
+source ./venv/bin/activate
+pip install -r requirements.txt
+```
+
+After that you will have all needed libraries so the last step is to copy `config.json.sample`
+into `config.json` and adjust it to your needs.
