 Submit your proposal
 --------------------------
 
+Please make sure you read this entire page before submitting your proposal, and pay particular attention to the following points:
+
+- **Spoilers** it's pretty normal not to want to include your main point in your abstract, but please make sure to highlight it for the selection committee!
+- **Research** we don't need all talks to be about a new topic, but if you're suggesting a talk that looks really similar to one that was given last year, show you know that, and mention why yours is different.
+- **Tooling** we're pretty serious about preferring talks about people, process or principles than talks about tooling. If you are submitting a proposal about tooling, tell us what makes this one special.
+- **Example proposal** so you know what we expect to see in each field.
+
 Submit your proposal at {{cfp.url}}. You'll need to sign up for a Pretalx account, unless you already have one from a previous conference.
