# Project Description

## Dev Environment Setup for OS X.
* Ruby 2.5.1
\`\`\`
$ brew install ruby@2.5
\`\`\`

[To install ruby on other platform please refer](https://www.ruby-lang.org/en/documentation/installation/)
* Bundler v1.16.3
\`\`\`
$ gem install bundler -v 1.16.3
\`\`\`

## Test instructions
\`\`\`
$ bundle exec rspec
\`\`\`

## Code Coverage
\`\`\`
$ bundle exec rspec
\`\`\`
It will create a folder with the name coverage and on clicking the index.html inside coverage folder you can find the code coverage.

## Using Cycromatic
\`\`\`
$ cycromatic .
\`\`\`
It will output the cyclomatic complexity of the code.

[To know further please see](https://github.com/soutaro/cycromatic)

## How to use
