The on-ramp: from nothing to a first result.

If you have a funding decision and twenty minutes, this is where to begin. The pages here take you through building a small model in the Portal, running it, and reading what came back — in that order, with nothing assumed.

• Your first model in 20 minutes — build a model from a worked example and read its result cards.
• Example models — five small models, one per cause area, each runnable as it stands.
• Getting access — who can sign in, and how.

These pages are being written. Until they land, the Reference documents every input and every result, and the Glossary gives one name for each thing.
