In order to install the app you need to run

go get -u github.com/slomek/pomodogo

In order to have a default notification icon, you may want to build it manually:

make
make pack

For the most basic usage you just need to call the app's name:

pomodogo

and the counter should start immediately, by default counting down 25 minutes. If the length is not good for you, it can be changed via a parameter, eg. the following

pomodogo -duration 10m

will count down 10 minutes.

The tool is based on a time management technique called Pomodoro Technique®. You can read more on it at its official webpage.
