Installing Sugarkube is simple because it’s a single golang binary. Just download the latest release and copy it somewhere like /usr/local/bin making sure it’s executable (with chmod +x sugarkube).

You’ll also need a global config file. Download the default one and copy it to your home directory:

mkdir ~/.sugarkube
mv sugarkube-conf-basic.yaml ~/.sugarkube/sugarkube-conf.yaml

Test your installation by running sugarkube version. If it prints various version information and doesn’t print an error, you’re good to go.

If you’re running Bash you can enable command completion with . <(sugarkube completion). Add that to your ~/.bashrc (Linux) or ~/.bash_profile (OSX) files to enable completion automatically when you create a new shell.
