 1. Modify the server.d file because several import paths are currently hard-coded. (See also: the warning at the beginnig that this is alpha-quality)
 1. Configure your text editor to call the dcd-client program
 1. Start the dcd-server program before editing code.
+
+#Client usage
+
+##Get autocomplete information
+The primary use case of the client is to query the server for autocomplete information.
+To do this, provide the client with the file that the user is editing along with the
+cursor position (in bytes).
+```dcd-client -c123 sourcefile.d```
+
+This will cause the client to print a listing of completions to *stdout*.
+The client will print either a listing of function call tips, or a listing of of
+completions depending on if the cursor was directly after a dot character or a
+left parethesis.
+
+###Dot completion
+When the first line of output is "identifiers", the editor should display a
+completion list.
+####Output format
+A line containing the string "identifiers" followed by the completions that are
+available, one per line. Each line consists of the completion name folled by a
+tab character, followed by a completion kind
+#####Completion kinds
+* c - class name
+* i - interface name
+* s - struct name
+* u - union name
+* v - variable name
+* m - member variable name
+* k - keyword, built-in version, scope statement
+* f - function or method
+* g - enum name
+* e - enum member
+* p - package name
+* M - module name
+
+####Example output
+	identifiers
+	parts	v
+	name	v
+	location	v
+	qualifier	v
+	kind	v
+	type	v
+	resolvedType	v
+	calltip	v
+	getPartByName	f
+
+####Parenthesis completion
+When the first line of output is "calltips", the editor should display a function
+call tip.
+#####Output format
+A line containing the string "calltips", followed by zero or more lines, each
+containing a call tip for an overload of the given function.
+#####Example output
+	calltips
+	ACSymbol findSymbolInCurrentScope(size_t cursorPosition, string name)
+
+##Clear server's autocomplete cache
+```dcd-client --clearCache```
+
+##Specify server port
+```dcd-client -p4242```
+
+##Add import search path
+```dcd-client -Ipath/to/imports```
+
+##Shut down the server
+```dcd-client --shutdown```
+
+#Server usage
+## Import directories
+The ```-I``` option allows you to specify directories to be searched for modules
+## Port number
+The ```--port``` or ```-p``` option lets you specify the port number that the server will listen on
