# Notes and slide images
A slide carries its script in a `<Notes>` tag — the words said while it is up,
never shown on it — and a deck its `context`: what the talk is, for whom, in
what tone. Every slide is also a PNG at `<deck file>/<n>.png`, so an agent
writing the notes can look at the slide it is writing for.
```markdown
# Why devpage
<Notes>
Every team writes docs, and every team's docs drift from the code.
</Notes>
