+# Contributing
+
+If you have any issues or ideas for improvement you can send me an email to _thl-cmk[at]outlook[dot]com_.
+
+For some fixes/improvements I migth need a _snmpwalk_ from the device in question.
+This must contain
+
+- .1.3.6.1.2.1.1.1 sysDescr 
+- .1.3.6.1.2.1.1.2 sysObjectID
+
+and all the SNMP OIDs used in the plugin.
+
+If you run the _snmpwalk_ command, please uses these options _**-ObentU**_ in addition to your snmp options like community, version etc.
+For example:
+```
+snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.2.1.1.1 > hostname.snmpwalk
+snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.2.1.1.2 >> hostname.snmpwalk
+snmpwalk -v2c -c public -ObentU 10.10.10.10 .1.3.6.1.4.1.9.9.147.1.2.2.2.1.5.40 >> hostname.snmpwalk
+```
