+# DESIGN
+This document describes the design of this project. The main purpose is to describe the interface between the client and the server, but I might document other useful information here, too.
+
+## Client/Server Communication
+All communication is done through JSON.
+
+### Client Requests
+Clients can make requests to the server by sending a JSON object containing two fields:
+* "request", which is a string of name of the request being made
+* "parameters", which is an object whose structure depends on the request. It contains a named list of the request's parameters
+
+### Server Responses
+Upon receiving and handling a request, the server will send a response object with the following fields:
+* "success", a boolean that indicates whether the request succeeded
+* "response", an object whose structure depends on the request. It contains data relevant to the request
+
+### Example Request and Response
+An example request might look as follows:
+```
+{
+    "request": "create-world",
+    "parameters": {
+        "name": "test world",
+        "size": {
+            "height": 10,
+            "width": 15,
+        }
+    }
+}
+```
+
+A success response might look like:
+```
+{
+    "success": true,
+    "response": {
+        "world-id": 69420
+    }
+}
+```
+
+Or, in the case of an error:
+```
+{
+    "success": false,
+    "response": {
+        "code": 69
+        "message": "A world with this name already exists"
+    }
+}
+```
