+====== Showing the Information with the Screen ======
+As the screen gets the ScreenHandler in its constructor, we have access to the property delegate from above and can render the integer on screen
+<code java [enable_line_numbers="true"] BoxScreen.java>
+public class BoxScreen extends HandledScreen<ScreenHandler> {
+    private static final Identifier TEXTURE = new Identifier("minecraft", "textures/gui/container/dispenser.png");
+    BoxScreenHandler screenHandler;
+    public BoxScreen(ScreenHandler handler, PlayerInventory inventory, Text title) {
+        super(handler, inventory, title);
+        //we save a reference to the screenhandler so we can render the number from our propertyDelegate on screen
+        screenHandler = (BoxScreenHandler) handler;
+    }
+    @Override
+    protected void drawBackground(MatrixStack matrices, float delta, int mouseX, int mouseY) {[...]}
+    @Override
+    public void render(MatrixStack matrices, int mouseX, int mouseY, float delta) {
+        //We just render our synced number somewhere in the container, this is a demonstration after all
+        //the last argument is a color code, making the font bright green
+        textRenderer.draw(matrices, Integer.toString(screenHandler.getSyncedNumber()), 0, 0, 65280);
+        renderBackground(matrices);
+        super.render(matrices, mouseX, mouseY, delta);
+        drawMouseoverTooltip(matrices, mouseX, mouseY);
+    }
+    @Override
+    protected void init() {
+        super.init();
+        // Center the title
+        titleX = (backgroundWidth - textRenderer.getWidth(title)) / 2;
+    }
+}
+</code>
+====== Result ======
+As the registration of the ScreenHandler is identical to the first tutorial we can see the result already!
+When the BlockEntity is placed it will increase the syncedInt by one each tick, when we look inside the container the integer will
+automatically be synced to the client and rendered in the top left corner.

+If you want a more realistic example, you might want to have a look at AbstractFurnaceEntity and AbstractFurnaceScreenHandler in the minecraft code.
