How to install and run this tool?

How can i use it in terminal as you did in the example?

I did install it correctly with cabal install, but I didn't make the link yet so:

enter the project directory
cabal install
sudo ln -s ~/.cabal/bin/reserve /usr/local/bin/reserve

@felipexpert Do you have ~/.cabal/bin in your PATH?
