Getting started

Start here. These pages take you from an empty environment to a priced trade and a book that reports its risk. Read them in order; everything after this section assumes the picture the mental model draws.

Pages

Page	What it covers
Install helixio and check it runs	how-to: install the pinned build in Rust or Python, and check it
first-trade	tutorial: quotes become a market, a template drafts a swap; value, par rate and DV01
the-mental-model	explanation: sheet, market, instrument, book, verb, the chain every page builds on
load-the-desk-sheets	how-to: load the shared market data the reference pages' examples import
coding-agents	how-to: install the helixio skill in Claude Code or Codex, and use it

Where next

The market shows each link of the chain in depth: how a sheet is read, how a curve is solved from helpers, how a market holds several dates, how it fetches, and how a book carries it.
