+# Developing Rails applications
+
+## Coding Style
+* Use soft-tabs with a two space indent.
+* Never leave trailing whitespace.
+* Use spaces around operators, after commas, colons and semicolons, around { and before }.
+  ```
+  sum = 1 + 2
+  a, b = 1, 2
+  1 > 2 ? true : false; puts 'Hi'
+  [1, 2, 3].each { |e| puts e }
+  ```
+
+* No spaces after (, [ or before ], ).
+  ```
+  some(arg).other
+  [1, 2, 3].length
+  ```
+
+* Use empty lines between defs and to break up a method into logical paragraphs.
+
+  ```
+  def some_method
+    data = initialize(options)
+    data.manipulate!
+    data.result
+  end
+  
+  def some_method
+    result
+  end
+  ```
