+# IOT Data
+
+Just a tiny service for posting small datasets to a server which can get fetched by other services afterwards.
+
+It just keeps the data in RAM so it is definetely not for big stuff and log term storages.
+
+## Usage
+
+Read data:
+```
+curl http://iot-data.clerie.de/data/sensor1/
+```
+
+Write data:
+```
+curl -X POST -d 'hello world!'' -H 'Content-Type: text/plain' http://iot-data.clerie.de/ingress/asdf1234/
+```
+
+Content type is considered too:
+```
+curl -X POST -d '{"key": "value"}' -H 'Content-Type: application/json' http://iot-data.clerie.de/ingress/asdf1234/
+```
+
+## Deployment
+Init codebase
+```
+git clone https://github.com/clerie/iot-data.git
+cd iot-data/
+virtualenv -p python3 ENV
+cd ..
+```
+
+Create `config.json` with the following contents and edit values for your needs:
+
+```
+{
+  "sensor1": {
+    "key": "asdf1234"
+  },
+  "sensor2": {
+    "key": "supersecret"
+  },
+}
+
+```
+
+Starten und updaten lässt sich die Flask-App folgendermaßen:
+```
+cd iot-data/
+git pull
+source ENV/bin/activate
+pip install -r requirements.txt
+IOT_DATA_CONFIG=/path/to/config.json gunicorn iot_data:app
+deactivate
+```
