 # Quickstart
 ```typescript
-import {Backend, Frontend} from 'rpclibrary' 
+import {RPCServer, RPCSocket} from 'rpclibrary' 
+
+const port = 1234
+const host = 'locahost'
 
 const echo = (x) => x
 
-const server = new Backend.RPCServer(port, [{
+const server = new RPCServer(port, [{
     name: 'HelloWorldRPCGroup',
     exportRPCs: ()  => [
         echo, //named function variable
     ]
 }])
 
-const client = new Frontend.RPCSocket(port, host)
+const client = new RPCSocket(port, host)
 
 client.connect().then(async () => {
     const r0 = await client['HelloWorldRPCGroup'].echo('Hello')
 You should unhook the client socket once you're done with it as not to cause security or control flow issues.
 
 ```typescript
-import {Backend, Frontend, Utils} from 'rpclibrary'
+import {RPCServer, RPCSocket} from 'rpclibrary'
+
+const port = 1234
+const host = 'locahost'
 
 const callbacks:Map<string, Function> = new Map()
 
-const server = new Backend.RPCServer(port, [{
+new RPCServer(port, [{
     name: 'HelloWorldRPCGroup',
     exportRPCs: ()  => [
         function  triggerCallbacks(...messages){ callbacks.forEach(cb => cb.apply({}, messages)) },
     ]
 }])
 
-const client = new Frontend.RPCSocket(port, host)
+const client = new RPCSocket(port, host)
 client.connect().then(async () => {
     const res = await client['HelloWorldRPCGroup'].subscribe(async (...args:any) => {
         console.log.apply(console, args)
 If you need to include further response data into your `SubscriptionResponse` you can extend it using the server's first generic parameter `SubResType`
 
 ```typescript
-new RPCServer<{extension: string}>(port, {
+new RPCServer<{extension: string}>(port, [{
     name: 'MyRPCGroup',
     exportRPCs: ()  => [{
         name: 'subscribe',
                 extension: 'your_data_here' //tsc will demand this field
             }
         }
-    }]
-})
+    }]}
+])
 
 ```
 
 
 /* OR */
 
-const client = new Frontend.RPCSocket(port, host)
+const client = new RPCSocket(port, host)
 client.connect<MyInterface>().then((async (client) => {
     const r = await client.Group2.echo("hee") //tsc knows about available RPCs 
 }))
