The installation is the uncompression of the downloaded package where you want to install the package.

$ tar zxf kcn-vX.X.X-linux-amd64.tar.gz


$ tar zxf kcn-baobab-vX.X.X-linux-amd64.tar.gz

Note: it is recommended that the uncompressed directory kcn-linux-amd64/bin path should be added to the environment variable $PATH to run the kcn and kcnd globally. As an example,

The other sections assume that the path is added to the variable.
