Removed the MQTT_MAX_CONNECTION_ATTEMPTS option and replaced it with a MQTT_ACTIVE option. If MQTT support is activated the script will try to connect to the MQTT broker continously and now also the reconnect is functional.

+# LedControl
+
+## Wiring
+
+## Installation
+```
+    sudo apt-get install -y python3-pip git
+    sudo pip3 install adafruit-ws2801
+    sudo pip3 install paho-mqtt
+
+    git clone https://github.com/Tom-Hirschberger/PythonLedControl.git /home/pi/ledcontrol
+
+    cd /home/pi/ledcontrol
+    cp ledcontrol.env.example ledcontrol.env
+
+    sudo ln -s /home/pi/ledcontrol/ledcontrol.service /etc/systemd/system/ledcontrol.service
+    sudo systemctl enable ledcontrol
+```
+
+## Configuration
+    Open the file /home/pi/ledcontrol/ledcontrol.env in your favorit editor. In example:
+
+```
+    nano /home/pi/ledcontrol/ledcontrol.env
+```
+
+### Options ###
+| Option | Description | Type | Default |
+| ------ | ----------- | ---- | ------- |
+| MQTT_ACTIVE | If the script should be run without MQTT support this option can be used (0=disabled, 1=enabled). | Integer | 1 |
+| MQTT_CLIENT_NAME | The name the client will be use while connecting to the MQTT Broker | String | "raspled" |
+| MQTT_BROKER_ADDRESS | The hostname or ip address of your MQTT Broker | String | "192.168.1.2" |
+| MQTT_TOPIC_PREFIX | The ledcontrol service not only reacts on button presses but also on MQTT messages. All these messages will be prefixed with this string | String | "raspled/" |
+| LED_BTN_ONE_GPIO | The GPIO number the first button is connected to (GPIO not PIN number!). | Integer | 17 |
+| LED_BTN_TWO_GPIO | The GPIO number the second button is connected to (GPIO not PIN number!) | Integer | 27 |
+
+
+## MQTT Messages ##
+The script can be configured during runtime by sending MQTT messages to your MQTT Broker. Be sure to send the messages with the configured prefix. The default is "raspled/" and will be used in the following examples.
+
+### /raspled/output ###
+Switch the led strip on or off
+
+"on" -> Switch all leds on
+"off" -> Switch all leds off
+
+### /raspled/get_status ###
+Fetch the current configuration als MQTT message with the data in json format. The message will be send to the topic "raspled/status"
+
+### /raspled/config ###
+### /raspled/color/r ###
