How to install and use?
The best way of installing is by Alcatraz. Install Alcatraz followed by the instruction, restart your Xcode and press ⇧⌘9. You can find VVDocumenter-Xcode in the list and click the icon on left to install.
If you do not like the Alcatraz way, you can also clone the repo. Then build the VVDocumenter-Xcode target in the Xcode project and the plug-in will automatically be installed in ~/Library/Application Support/Developer/Shared/Xcode/Plug-ins. Relaunch Xcode and type in /// above any code you want to write a document to.
If you want to use other text beside of /// to trigger the document insertion, you can find a setting panel by clicking VVDocument in the Window menu of Xcode. You can also find some other useful options there, including setting using spaces instead of tab in the panel or changing the format of generated documentation.
