LaserIO v 1.3.0

Found under the Card category in the Redstone Card chapter:

"level" is probably suppose to be "lever"

After noticing this I did read the rest of the book, I did not notice anything else, I am also notoriously bad at reading so take this with a grain of salt.

Apologies if this does constitute a bug. A bug report felt a little bit like overkill though. Especially the required steps to recreate section "Step one: open book, step two: read"

Thanks for the heads up :)
