 ## Idea
 
 If you get access to a [PCAP](https://en.wikipedia.org/wiki/Pcap) file, for example during a CTF or captured on your own, you usually have the problem of overlooking all the relevant information to get a basic idea of the capture file. This gets worse if the capture file includes lots of white noise or irrelevant traffic - often included in the capture file to cloak *interesting* packets in a bunch of packets to YouTube, Reddit, Twitter and others.

 Simply run
 
-`go get github.com/maride/pancap`
+`go get git.darknebu.la/maride/pancap`
 
 This will also build `pancap` and place it into your `GOBIN` directory - means you can directly execute it!
