Preface to the Summit Event Language Guide

Learning how to build models that can be deployed as apps and used anywhere.


This isn't a book (yet), but if it were, it'd look something like this.


The following pages will guide you through the technical aspects of building with Summit Event Language, or SEL. The modeling environment that uses SEL is available at

We encourage you to start by reading The Summit Way, as we find a lot of the friction that comes from first using and learning SEL stems from the modeler's understanding of what's really going on inside their model when they click Run.

Alternatively, you can start by diving into Events, the first page of The Topical Guide. This guide is broken down into sections that summarize event types, the shapes and functions you use to build models.

For additional help, or help while in the modeling environment itself, click 'Help' in the top navigation bar. We're always happy to chat!
