+### Presentation formats
+
+SeattleJS is equipped to support a few different presentation formats:
+
+- **Lightning talks** are *5-10 minute* sessions that briefly cover a topic. They tend to be more casual, and are a great fit for sharing something new you learned, and interesting problem you solved recently, and other topics that don't require a ton of depth.
+- **Tech sessions** are *20-30 minutes* and cover a technical topic in depth. Full sessions are usually accompanied by slides or demos. These should cover a topic in reasonable depth. These are also a great way to test out a topic before submitting or presenting at a conference.
+- **Workshops** are *interactive* sessions that are *45 minutes or longer*. In a workshop, the presenter guides the audience through one or more **hands-on coding activities** that they complete on their own computers.
+
+If you've learned something new or have some hard-won wisdom to share, you'll find SeattleJS a warm and welcoming place to speak.
