Why to validate commits and reasons behind each rule

We all want always to become better developers, in order to do so, we need to learn new things every day. One of the strategies to learning and using new ways to work, is to understand the reasons behind them.

In order to get more insights behind why it is important to validate commit messages, and the whys behind each of the rules in this package, check out the wiki in github

Installation and Configuration

To install it run:

$ npm i fit-commit-js

Then you need to install the commit hook in your repo by doing:

$./node_modules/fit-commit-js/bin/fit-commit-js.js install

Then create your fitcomitjsrc.{yml, yaml, json} with your settings, and place it at the root of your project.

You can also add a section in your package.json called: "fitcommitjsConfig", and add there your settings.
