+Build and fire up the container stack with `docker-compose up --build -d`.
+
+Configuration can be done through `environment` variables in `docker-compose.yml`:
+
+  * `MQTT_HOST` - mqtt server, defaults to `localhost`
+  * `MQTT_ID` - id to use for connecting to mqtt server, defaults to `speedtest`
+  * `MQTT_TOPIC` - topic to push data to, defaults to `speedtest/status`
+  * `MQTT_OPTIONS` - additional mqtt options, defaults to `-V mqttv311`
+  * `MQTT_USER` - user for mqtt server
+  * `MQTT_PASS` - password for mqtt server
+  * `SPEEDTEST_OPTIONS` - additional options for `speedtest-rs`
+  * `SPEEDTEST_INTERVAL` - interval in which to run speedtest, in seconds, defaults to 60
