• Please review overall format - Not sure I like Delivery Plan all in one VERY long page, but thought to have everything in one place.
• Also can you please review "Common pitfalls and troubleshooting guidance"?

Overall, I think the structure of a workshop is good. I agree, the single step for the delivery of the build instructions can be a lot, especially for more complex workshops in the future. I wonder if we could provide alternative mediums for that content, like prepared slides, that teachers can duplicate and edit, or we just leave it up to them to create that resource as needed.

I also wonder if we can create a table of contents at the top of that page with links to the various sections, so folks can jump around from the top of the page.

Do we expect students to use the non-workshop codelab as their view of the content while the teacher goes through the delivery plan with extra context about how to handle troubleshooting and other concerns?
