In any case, Rails will create a folder in your working directory called blog. Open up that folder and explore its contents. Most of the work in this tutorial will happen in the app/ folder, but here's a basic rundown on the function of each folder that Rails creates in a new application by default:

This requires editing the new and edit views, and adding a new template. The new _form.html.erb template should be saved in the same app/views/posts folder as the files from which it is being extracted:
