# Features overview
Highlighted, sales-driving features of Helix, grouped by the goal they serve. Each links to its own page — what it does, why it helps sales, and how to turn it on. The setup details live on the relevant section, block, or theme-settings page; a feature page gives the sales angle and points you there.
> **What belongs here:** capabilities a merchant would go looking for by *outcome* ("how do I create urgency?", "how do I raise average order value?"). Plain layout sections and styling options stay in their own reference pages, not here.
