+Based on your feedback at the end of the last meetup, we have decided to try a
+**Crate Polishing Meetup** this time around. This basically means we will choose a
+crate we consider important and try to make it better/nicer to use. Whether that
+means adding documentation, examples, or fixing bugs is up to you. Which crate
+to polish will be decided at the beginning of the meetup.
+
+If you have a suggestion, feel free to [comment in our planning issue][1]. Don't
+be shy to suggest your own crates – it's even better if the maintainer/author is
+present!
+
+Oh, and before we forget: This is actually a preliminary plan! Do you remember how
+last year we had Alex Crichton, a member of the Rust core team, celebrate Rust's
+1.0 anniversary [with us][2]? We might have another visitor from the core team in
+April this time! We can't make any promises, but will let you know as soon as we
+have more details!
