+# Prusa Connect Prometheus Exporter
+
+Version v0.1.0 of this exporter supports the pre-4.4.0 changes to the Prusa Connect API (non-API-key version).
+
+Current master branch supports the new, 4.4.0-beta2 release of Prusa Connect as well as the older API.
+
+## Usage
+
+`./prusa-connect-exporter -h`
+
+* `apikey`
+    Prusa Connect API key (see Main Menu -> Settings -> Network on the printer).
+    If no key is provided, exporter assumes the older API layout when querying the printer.
+* `hostname`
+    Hostname the Prusa Connect API is available at (assumes http) (default "localhost")
+* `interval`
+    How often, in seconds, to query the API (default 2)
+* `path`
+    Local path to export metrics on (default "metrics")
+* `port`
+    Local port to export metrics on (default "2112")
