In order to build Kraken you will need to have Go installed on your system. We recommend using Go >= 1.11 in order to leverage the native support for Go Modules (if it is not available in your package manager, you can use something like gvm).
Firstly, download Kraken:
$ git clone https://github.com/botherder/kraken.git
$ cd kraken
Most Go libraries dependencies are available to install through:
$ make deps
