+### Kubearmor receiver config.
+
+There are two configuration options for the receiver:
+
+- endpoint:
+   This specifies kubearmor's server API URL. 
+- logfilter
+   This is used to specify which logs one is interested in. If none is specified all logs are received. There are three filters:
+   - kubearmorLogs:
+      Use this if you want to see kubearmor's application logs.
+   - policy
+     Use this if you want to see alerts.
+   - system
+     Use this if you want to see logs about insights gotten by kubearmor aboutt host system.
+   - all
+      Use this if you want to see the entire log messages.
+Refer to [kubearmor_receiver/testdata/config.yml](kubearmor_receiver/testdata/config.yml) for a visual example on how to
+place the options in your configuration file.  
+
