+# Minimalistic web app template
+
+*One-file backend, one-file frontend*
+
+Backed by Sinatra and optionally Grape for APIs.
+
+Single-page client app with Backbone.js and Bootstrap.
+
+Great for demos and quick hacking. Production use at your own risk.
+
+
+## What you get
+
+**Back-end**
+  * Sinatra and Grape
+  * Unicorn server
+  * ActiveRecord
+  * Ready to deploy on Heroku
+  * Database migrations with `rake db:migrate`
+  * A Rails-like console with `rake console`
+
+**Front-end**
+  * Bootstrap
+  * Backbone.js
+  * Lo-dash
+  * jQuery
+
+
+## What you don't get (by design)
+
+  * A testing framework (but it's easy to add if you need one)
+  * Well-organized models, views, controllers, presenters...
+  * CoffeeScript. Just good old Javascript straight into `views/index.erb`.
+  * LESS or SASS. And guess where your CSS goes?
+
+
+## Usage
+
+Create an `.env` file with the following:
+
+```bash
+# the URL of your application database
+DATABASE_URL=postgres://localhost/app_name
+```
+
+Run with `foreman`:
+
+```bash
+$ foreman start -p 5000
+```
+
+
+## Development
+
+### The two files
+
+All the frontend stuff goes in `views/index.erb`
+
+All the backend stuff goes in `app.rb`. The root route should render
+`index.erb` which loads your single-page app, and other routes should
+expose a JSON api that the app talks to.
+
+### Rake tasks
+
+> Remember to always run these with `foreman`, or your environment
+> variables will be ignored: `foreman run rake task_name`
+
+  * `rake db:migrate` and `rake db:rollback` run database
+    migrations, _à-la_ Rails
+
+  * `rake console` opens a shell into the app, just like
+    `rails console`
+
+  * `rake routes` lists the routes exposed by the App
