 # TCPColor
 Add color to a basic tcpdump with standard python3 libraries.
+
+## Usage
+
+```shell
+$ tcpdump -l -nnq <tcpdump filter> | tcpcolor.py
+```
+
+I generally always use these flags so this utility will only work properly when using them. 
+
+`-nn    Don't convert protocol and port numbers etc. to names either.`
+
+`-q     Quick (quiet?) output.  Print less protocol information so output lines are shorter.`
