 `spaceapid` serves a [SpaceAPI](https://spaceapi.io)-compatible JSON on port 8080:
 
 ```shell
-curl -X GET http://localhost:8080
+$ curl -X GET http://[::1]:8080 | jq
+{
+  "api_compatibility": [
+    "14"
+  ],
+  "space": "CCCHH",
+  ...
+}
+
 ```
 
+## Configuring
+
+spaceapid has to be configured via one or multiple json files.
+A sample configuration is provided as [config-template.json](./config-template.json).
+The config consists of three parts:
+
+- `"credentials"`
+	- List of Username/Password credentials for HTTP BasicAuth
+- `"dynamic"`
+	- The configuration for the dynamic parts of the message
+- `"response"`
+	- The static (pre-filled) parts of the response
+
+See [Running](#running) for details.
+
+## Updating values
+
 The state of the boolean `state->open` property can be modified via `/state/open`:
 
 ```shell
-curl -X PUT -u user:password -d true http://localhost:8080/state/open
+curl -X PUT -u user:password -d true http://[::1]:8080/state/open
+```
+
+The same is true for the endpoints for sensors configured under `"dynamic"`.
+Currently only `temperature` and `humidity` are implemented.
+
+```shell
+curl -X PUT -u user:password -d 23.42 http://[::1]:8080/{temperature,humidity}/location[/name]
 ```
