 I never figured out why and what caused it; but with the setup provided in this repo it does not happen.
 
 ### How?
-@TODO
+The instructions are for Raspbian and the assumption that the script will be installed in */opt*
+
+* Install dependencies:<br>
+> 
+>    sudo apt update<br>
+>    sudo apt install git python-pip<br>
+>    sudo python -m pip install --upgrade pip setuptools wheel<br>
+
+* Download the repository:<br>
+>
+>    cd /opt<br>
+>    git clone https://code.shdx.org/Der_Leopold/Zabbix-DHT.git
+
+* Optional: Install the Adafruit tool that reads the sensor data<br>
+Skip this step if you already have it.<br>
+>
+>    cd Zabbix-DHT/external/Adafruit_Python_DHT<br>
+>    sudo python setup.py install
+
+* Edit the *readSensor* script and change as needed. At least the two variables **SENSOR** and **GPIOPIN** have to be adjusted to your setup.
+* Run the script:<br>
+>
+>   ./readSensor<br>
+
+* If everything works, it the script created the output file with content similar to this:<br>
+>
+>    Timestamp=1543420306<br>
+>    Temperature=23.7<br>
+>    Humidity=39.7
+
+* Set up a cronjob to keep the output file up to date:
+>
+>    crontab -e
+```
+    */1 * * * *     /opt/Zabbix-DHT/readSensor
+```
+
+* Copy the file userparameter_dht.conf to your Zabbix config directory:
+>
+>    sudo cp userparameter_dht.conf /etc/zabbix/zabbix_agentd.conf.d/
+
+* Restart Zabbix agent to pick up the change:
+    >sudo service zabbix_agentd restart
+
+* Finally, import the template (*templatedht.xml*) into Zabbix and assign it to the host
+
+After a few minutes you should see data starting to come in.
 
 ### Who?
 I'm codeing purely as a hobby and do it far too infrequent to have any kind of practice. So please bear with me if the code is amateurish...
