As far as I can tell, the solutions to the tour exercises in the /solution folder are not linked in the tour. Users that run the tour locally from the repo may see the folder, but the ones that visit the online version of the tour won't.

The solutions repo at https://github.com/golang/tour/tree/master/solutions should be linked somewhere.

Either in the introduction, or in the slide of the first exercise.
