-JScript is an engine, capable of running EcmaScript 5, written entirely in Java. This engine has been developed with the goal of being easy to integrate with your preexisting codebase, **THE GOAL OF THIS ENGINE IS NOT PERFORMANCE**. My crude experiments show that this engine is 50x-100x slower than V8, which, although bad, is acceptable for most simple scripting purposes.
+JScript is an engine, capable of running EcmaScript 5, written entirely in Java. This engine has been developed with the goal of being easy to integrate with your preexisting codebase, **THE GOAL OF THIS ENGINE IS NOT PERFORMANCE**. My crude experiments show that this engine is 50x-100x slower than V8, which, although bad, is acceptable for most simple scripting purposes. Note that although the codebase has a Main class, this isn't meant to be a standalone program, but instead a library for running JavaScript code.
 
 ## Example
 
-The following will create a REPL using the engine as a backend. Not that this won't properly log errors. I recommend checking out the implementation in `Main.main`:
+The following is going to execute a simple javascript statement:
 
 ```java
-var engine = new PolyfillEngine(new File("."));
+var engine = new Engine();
-var in = new BufferedReader(new InputStreamReader(System.in));
+// Initialize a standard environment, with implementations of most basic standard libraries (Object, Array, Symbol, etc.)
-engine.start();
+var env = Internals.apply(new Environment());
 
-while (true) {
+// Queue code to load internal libraries and start engine
-    try {
+var awaitable = engine.pushMsg(false, env, new Filename("tmp", "eval"), "10 + Math.sqrt(5 / 3)", null);
-        var raw = in.readLine();
+// Run the engine on the same thread, until the event loop runs empty
+engine.run(true);
 
-        var res = engine.pushMsg(false, engine.global(), Map.of(), "<stdio>", raw, null).await();
+// Get our result
-        Values.printValue(engine.context(), res);
+System.out.println(awaitable.await());
-        System.out.println();
-    }
-    catch (EngineException e) {
-        try {
-            System.out.println("Uncaught " + e.toString(engine.context()));
-        }
-        catch (InterruptedException _e) {  return; }
-    }
