Setting Up A Third Party Theme

So I watched a video on the site on this topic but wasn't able to make any progress with my site.

I have an existing site that I wanted to refresh so I purchased a theme from themes.getbootstrap.com.
Here's what I've done so far:

• unzipped the file
• copied the 5 folders (css, fonts, images, js, scss) from the theme's assets folder
• pasted the folders in my rails project folder vender/assets/themes/guidebook/
• added Rails.application.config.assets.paths << Rails.root.join('vendor') into my initializers/assets.rb file
• restarted my app but it's obvious that the styles are not there

I'd appreciate any help
