# Overview

> How inkly.json and inkly.lock configure an Inkly hub.

A hub is the public home for a collection of demos. Its config controls how that demo hub looks, which demos appear, how they are grouped, and what brand visitors see.

Most hub settings live in `inkly.json`. Inkly may also write `inkly.lock` to pin the exact runtime version used to render the hub.

```text theme={null}
inkly.json
inkly.lock
demos/
public/
```

## Edit hub settings

You can edit common hub settings in the Inkly platform without opening the repo. Open **Settings** → **Hub settings** to update the hub name, hero title, subtitle, layout, logo, favicon, logo link, CTAs, and runtime version.

For the platform workflow, see [Platform overview](/platform/overview#demo-hub-config).
