 This will ask Grafsy to replace all kinds of metric starting with **pdns** or aggregation prefixes  **^(SUM|AVG|MIN|MAX).pdns** to **servers.HOSTNAME.software.pdns** where *HOSTNAME* will be replaced with os.Hostname() output
 
+# Client
+
+The `grafsy-client` binary is implemented for easy metrics sending from generators to a grafsy daemon. You only need to specify the config file, if a not-default one is used.  
+It sends either metrics from specified files or from STDIN.
+
+```
+Usage: ./build/grafsy-client [args] [file1 [fileN...]]
+   Or: metrics-generator | ./build/grafsy-client [args]
+```
