+## Default Javascript Compilation
+
+Add this line to your `config/application.rb` as show below, above the `config.assets.enabled = true`:
+
+```ruby
+config.app_generators.javascript_engine :typescript
+
+# Enable the asset pipeline
+config.assets.enabled = true
+```
+
+If you don't want it to be the default javascript engine, you can also use it adhoc as show below:
+
+```ruby
+rails g controller MyController --javascript_engine=typescript

 ## Referenced TypeScript dependencies
 
 `typescript-rails` recurses through all [TypeScript-style](https://github.com/teppeis/typescript-spec-md/blob/master/en/ch11.md#1111-source-files-dependencies) referenced files and tells its [`Sprockets::Context`](https://github.com/sstephenson/sprockets/blob/master/lib/sprockets/context.rb) that the TS file being processed [`depend`s`_on`](https://github.com/sstephenson/sprockets#the-depend_on-directive) each file listed as a reference. This activates Sprocket’s cache-invalidation behavior when any of the descendant references of the root TS file is changed.
