How to install a Start Bootstrap theme on Ruby on Rails 4 using Sass?

I want to install a theme called Grayscale of Start Bootstrap and I don’t know how to do it.

Install a new Ruby on Rails by running >> rails new grayscale. Navigate to your project folder >> cd grayscale then run the following commands:

Sass / SCSS

>> git clone https://github.com/blackfyre/https://github.com/blackfyre/grayscale-sass.git.git
>> cd grayscale-sass
>> bower install
>> cd ..
>> mv app/assets/stylesheets/application.css app/assets/stylesheets/application.scss

Then edit app/assets/stylesheets/application.scss. This file should contain only the following line of code:

@import '../../../grayscale-sass/assets/sass/main.scss';

Javascipt

Edit app/assets/javascripts/application.js. This file should contain the code like that shown below:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .


//= require grayscale-sass/assets/bower_components/jquery.easing/js/jquery.easing.js
//= require grayscale-sass/assets/bower_components/bootstrap/dist/js/bootstrap.js
//= require grayscale-sass/assets/js/grayscale.js

Views

Create a controller called “welcome” with an action called “index”, by running the following command:

>> bin/rails generate controller welcome index

The app/views/welcome/index.html.erb and app/views/layouts/application.html.erb should be edit according grayscale-sass/index.httml

index.html.erb
