-1. Run ```git submodule update --init``` after cloning this repository to grab the various dependencies.
+1. Run ```git submodule update --init --recursive``` after cloning this repository to grab the various dependencies.
 1. Run ```make``` to build the client and server. (Or run build.bat on Windows). ```make ldc``` and ```make gdc``` will use the LDC or GDC compilers. The resulting executable will be much faster.
 1. Configure your text editor to call the dcd-client program. See the [wiki](https://github.com/Hackerpilot/DCD/wiki/IDEs-and-Editors-with-DCD-support) for information on configuring your specific editor.
 1. Start the dcd-server program before editing code. (Unless, of course, your editor's plugin handles this for you)
