+## Configuration reference
+
+The following configuration flags are supported by `multi-networkpolicy-tc`:
+```shell
+      --kubeconfig string                Path to kubeconfig file with authorization information (the master location is set by the master flag).
+      --master string                    The address of the Kubernetes API server (overrides any value in kubeconfig)
+      --hostname-override string         If non-empty, will use this string as identification instead of the actual hostname.
+      --network-plugins strings          List of network plugins to be be considered for network policies. (default [accelerated-bridge])
+      --pod-rules-path string            If non-empty, will use this path to store pod's rules for troubleshooting.
+      --add_dir_header                   If true, adds the file directory to the header of the log messages
+      --alsologtostderr                  log to standard error as well as files (no effect when -logtostderr=true)
+      --log_backtrace_at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
+      --log_dir string                   If non-empty, write log files in this directory (no effect when -logtostderr=true)
+      --log_file string                  If non-empty, use this log file (no effect when -logtostderr=true)
+      --log_file_max_size uint           Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
+      --logtostderr                      log to standard error instead of files (default true)
+      --one_output                       If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
+      --skip_headers                     If true, avoid header prefixes in the log messages
+      --skip_log_headers                 If true, avoid headers when opening log files (no effect when -logtostderr=true)
+      --stderrthreshold severity         logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=false) (default 2)
+  -v, --v Level                          number for the log level verbosity
+      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging
+      --log-flush-frequency duration     Maximum number of seconds between log flushes (default 5s)
+  -h, --help                             help for multi-networkpolicy-tc
