 #### 🧠 What do we know now?
 
-TODO
+* MyST documents can be built to multiple output formats, including PDFs.
+* Frontmatter is YAML metadata on a Markdown document that can tell MyST which documents
+  should be built as PDF.
+* [Typst](https://typst.app/) can be used as an alternative document engine to
+  $ \LaTeX $ for rendering PDFs by specifying `export.format: "typst"` in the frontmatter.
+* If you opened the collapsed section on quoting YAML, you know the author of this
+  document has been burned too many times. **Quote your strings**! 😁
