 ## Specific advice for tutorials
 
-Please note that tutorials are intended to be a hands-on experience for the attendees, rather than a
-long talk. This means that a substantial component of the workshop should involve exercises that
-your participants can complete on their own machines at their own pace. In the case you intend to do
-live coding, this should be either done slowly enough that attendees can follow along, or be able to
-be replicated in a later exercise.
-
-Please keep in mind that if attendees need to download materials for your tutorial, it is better to
-give them a heads up at least a couple of days prior. Bandwidth will be limited, and many public
-resources have some kind of rate limiting set up.
