Update installation instructions in Getting Started

[techpeace]

Just made some quick additions to the Getting Started docs to reflect what I needed to get the project up and running recently in my Rails 6 app.

In my Rails 5.x app with bootstrap 3, I have to add

      resource '/assets/**/*', header: :any, methods: %i[get]

to make glyphicons work.

I think we need a different solution for making cors work. Its common to need in development BUT its important to frame those configs as not being for production etc.

That makes sense, @jonspalmer. Would a comment or some additional context in the docs be sufficient?

Yes I think some other section of the docs mentioning cors and dev setup would be more appropriate
