 ### 4.1 Documentation
 
-If a function is more complicated than a simple O(1) operation, you should generally consider adding a doc comment for the function since there could be some information that the method signature does not make immediately obvious (A very useful plugin to do this [called VVDocumenter can be found here](https://github.com/onevcat/VVDocumenter-Xcode)). If there are any quirks to the way that something was implemented, whether technically interesting, tricky, not obvious, etc., this should be documented. Documentation should be added for complex classes/structs/enums/protocols and properties. All `public` functions/classes/properties/constants/structs/enums/protocols/etc. should be documented as well (provided, again, that their signature/name does not make their meaning/functionality immediately obvious).

 After writing a doc comment, you should option click the function/property/class/etc. to make sure that everything is formatted correctly.
