 This is an example application that demonstrates how to use the ShapeX library. It has a single starting point event called `request`, which returns an updated state, which changes the `counter`. When that state changes, the subscriber for the `counter` state fires.
 
 ```typescript
-import ShapeX from "@shapex/shapex";
+import { ShapeX } from "shapex";
 
 type AppState = {
   counter: number;

 At the core of your application is state. You start by initiating ShapeX with some initial state, like so:
 
 ```typescript
-import ShapeX from "@shapex/shapex";
+import { ShapeX } from "shapex";
 
 type AppState = {
   counter: number;
