No "Resources" page

[The page](https://github.com/lf-lang/embedded-lab/blob/main/src/Resources.md) `src/Resources.md` linked under [Section 3.1 _Prelab_](https://github.com/lf-lang/embedded-lab/blob/main/src/Tools.md#31-prelab) is not found. It's not a serious issue since the Prelab questions are simple enough, but I thought the 404 should be reported.
