[x] For slide 6: Add more explanation of the data visualization part (what the colors are, how it was made etc), and maybe also volcano plot. -> in notes
[x] IDEA: Create an FAQ document or resource somewhere (maybe on the workshop site?). We can start with the ones we already have, and add to it from the questions we get from every workshop. Then point to it from slides. -> Updated existing list of Key questions and topics in the slide show, but did not add link to wiki.
