-# connection checker
+# Connection Checker Nck
-the connection checker tests the internet connection and displays the status on the console
\ No newline at end of file
+This utility `nck` works similiar to traceroute and
+allows to record a traceroute.
+
+## Requirements
+
+To execute the traceroute, a privileged port must be opened. this
+requires special permissions.
+
+A prerequisite for reading incoming traffic is being able to either to
+be root or set the executable capability `CAP_NET_RAW`.
+
+Reminder: You can set the `CAP_NET_RAW` capability on an executable like
+this: `sudo setcap cap_net_raw+ep bin/nck`
+
+the connection checker tests the internet connection and displays the status on the console
+
+## Build
+
+Make build uses sudo to set the authorization for the program (see
+Requirements).
+
+```
+make build
+```
+
+
+## Run
+
+```bash
+Usage:
+ nck is the way to measure the path to a host.
+
+With this command the path from the localhost to the
+target computer can be recorded and the duration of the
+packet runtimes can be measured. Depending on the IP
+of the destination, either a V4 or V6 measurement is performed.
+
+Application Options:
+ -r, --realtime show the steps in real time
+ -f, --format=[table] output format, is not valid for real time mode. (default: table)
+ -h, --hops= maximal hops.
+ -m, --threshold= from the threshold value in milliseconds the value is marked in red (default: 20)
+
+Help Options:
+ -h, --help Show this help message
+```
