Let's get started by getting to know the toolkit:

• On the left side of the screen, find and click on it once. Notice the blue blocks that appear below.
• Find the block labeled Park. Click, hold, and drag it into the black space below, then release.

Press Run to see your changes. Look for feedback at the top of the graphics screen on the right (called the stage).

Click Submit and Next when you get a green check.

To navigate the page using the TAB key, first press ESC to exit the code editor.
