+## Lux::Controller
 
-Controllers are Lux view models
+Similar to Rails Controllers
 
-* all cells shoud inherit from Lux::Controller
-* `before`, `before_action` and `after` class methods supportd
-* instance_method `on_error` is supported
+* `before`, `before_action`, `after` and `rescue_from` class methods supportd
 * calls templates as default action, behaves as Rails controller.

+Render method can accept numerous parameters
+
+```ruby
+class MainController
+  def foo
+    render text: 'foo'
+    render plain: 'foo'
+    render html: '<html>...'
+    render json: {}
+    render javascript: '...'
+    render template: false, content_type: :text
+    render template: './some/template.haml', data: @template_data

+        # ...
+      when :js # /foo.js

+Definable callbacks
+
+```ruby
+before do ...        # before all
+before_action do ... # before action
+before_render do ... # before render
+after do ...         # after all
+```
+
+Definable class variables
+
+```ruby
+# define master layout
+# string is template, symbol is method pointer and lambda is lambda
+layout './some/layout.haml'
+
+# define helper contest, by defult derived from class name
+helper :global
+
+# custom template root instead calcualted one
+template_root './apps/admin/views'
