 All available collectors are listed in the above JSON. There are currently three sinks supported `influxdb`, `nats` and `stdout`. The `interval` defines how often the metrics should be read and send to the sink. The `duration` tells collectors how long one measurement has to take. An example for this is the `likwid` collector which starts the hardware performance counter, waits for `duration` seconds and stops the counters again. For most systems, the `likwid` collector has to do two measurements, thus `interval` must be larger than two times `duration`.
 
+# Installation
+
+```
+$ git clone git@github.com:ClusterCockpit/cc-metric-collector.git
+$ cd cc-metric-collector/collectors
+$ edit Makefile (for LIKWID collector)
+$ make (downloads LIKWID, builds it as static library and copies all required files for the collector)
+$ cd ..
+$ go get (requires at least golang 1.13)
+$ go build metric-collector
+```
+
+# Running
+
+```
+$ ./metric-collector --help
+Usage of metric-collector:
+  -config string
+    	Path to configuration file (default "./config.json")
+  -log string
