+# Contributing to ERPNext
+
+### New Features
+
+#### Don't Repeat Yourself (DRY)
+
+We believe that the most effective way to manage a product like this is to ensure that
+there is minimum repetition of code. So before contributing a function, please make sure
+that such a feature or function does not exist else where. If it does, the try and extend
+that function to accommodate your use case.
+
+#### Don't create new DocTypes Unless Absolutely Necessary
+
+DocTypes are easy to create but hard to maintain. If you find that there is a another DocType with a similar functionality, then please try and extend that functionality. For example, by adding a "type" field to classify the new type of record.
+
+#### Tabs or spaces?
+
+Tabs!
