Error in import code at start of chapter 3

[GerretS]

There's a box at the start of chapter 3 saying:

If you run the examples from the SBT console within Doodle they will just work. If not, you will need to start your code with the following imports to make Doodle available.

mdoc scala import doodle.core._ import doodle.core.Image._ import doodle.syntax._ import doodle.jvm.Java2DFrame._ import doodle.backend.StandardInterpreter._

That mdoc scala at the beginning shouldn't be there.
