# Lumia

**Who this is for:** anyone who wants to understand how Lumia works before building on it, issuing an asset on it, or evaluating it as infrastructure: developers, issuers, and operators alike.

This section sits directly under the home page, ahead of Build, because it's the mental model everything else assumes. Deploying a contract, issuing a real-world asset, or running a node all lean on the same underlying answers: how the chain reaches finality, what secures it, what its tokens do, and how compliance is designed in rather than bolted on. This is where those answers live.
