-#VIM Integration
+A plugin for using DCD with vim.
+
+Tested on Linux
+
+Installation and Configuration
+==============================
+Put the autoload and ftplugin folders in your vim runtime path.
+
+Compile DCD and put both dcd-client and dcd-server in your path, or set the
+global variable `g:dcd\_path` to where you put DCD.
+
+Usage
+===================
+When the filetype is D, use the `DCDstartServer` command to start the server
+and the `DCDstopServer` command to stop the server.
+
+Use the `DCDaddPath` command to add an import path to the server. Make sure you
+escape spaces!
+
+Use the `DCD` command to send arbitary commands to the server via the client.
+The syntax is the same as with `dcd-client`, so you can use it without
+arguments to print the help message.
+
+When the server is running, use `CTRL`+`x` `CTRL`+`o` to use DCD completion.
