-These are my notes about the internals of the Local Yarn source code. I wrote them mainly so I can quickly bring myself back up to speed after long absences from the code.
+These are my notes about the internals of the Local Yarn source code. I wrote them mainly so I can
+quickly bring myself back up to speed after long absences from the code. In other words, a personal
+reference, rather than a tutorial. You’ll get the most out of these notes if you have read
+@other-doc['(lib "pollen/scribblings/pollen.scrbl")], and worked through the tutorials by hand.
 
-This is a @racketmodlink[pollen]{Pollen} project, and it is a bit complicated. At the very least you should have read the @racketmodlink[pollen]{Pollen documentation}, and worked through the tutorials by hand, before delving into this code.
+If viewing these notes on the Fossil repository, links that lead out to sites other than
+@tt{docs.racket-lang.org} will not work within the “Code Docs” frame, due to the repository’s
+@link["https://content-security-policy.com"]{content security policy}. To follow such links,
+right-click and open the link in a new tab or window.
