+## Expectations
+
+Because the book is [printed](https://nostarch.com/rust), and because we want
+to keep the online version of the book close to the print version when
+possible, it may take longer than you're used to for us to address your issue
+or pull request.
+
+So far, we've been doing a larger revision to coincide with [Rust
+Editions](https://doc.rust-lang.org/edition-guide/). Between those larger
+revisions, we will only be correcting errors. If your issue or pull request
+isn't strictly fixing an error, it might sit until the next time that we're
+working on a large revision: expect on the order of months or years. Thank you
+for your patience!
