All the build information is provided online so that easy updates can be added. There is no paper documentation supplied. People have had plenty of success with this tried and tested design. If you put the parts in the right places and build as described, you'll have an instant school science project. There are some additional experiments described on the web-page for that bit of extra credit.

Breadboard Radio Modifications And Extras

For the electronics engineers there's also a fully detailed university level circuit description. You don't need to understand all this to make the kit work.
