First, install it: ```bash $ gem install loog ``` Then, use it like this: ```ruby require 'loog' Loog::VERBOSE.info('Hello, world!') ``` The gem is basically a provider of a few pre-configured loggers, which you can use for production (`Loog::REGULAR`) or for testing (`Loog::VERBOSE`). You can also shut it up with `Loog::NULL`. That's it. ## How to contribute Read [these guidelines](https://www.yegor256.com/2014/04/15/github-guidelines.html).
