1. 01

   Add the brain

   Reference the Navius.Primitives package, the headless engine. The styled components copy in as source; they are not a dependency.

   Terminal bash

   dotnet add package Navius.Primitives --prerelease

2. 02

   Register the services

   In Program.cs, register Navius (the portal registry and toast queue).

   Program.cs csharp

   builder.Services.AddNavius();

3. 03

   Add the theme

   Tailwind plus the OKLCH token theme. In production, build Tailwind v4 with the standalone CLI (no Node). For a quick start the Play CDN works; see Theming.

   App.razor html

   <link href="zits-ui.css" rel="stylesheet" />

4. 04

   Add a component

   The CLI copies a component's source (and its dependencies) into your project and rewrites the namespace.

   Terminal bash

   dotnet tool install -g navius --prerelease
   navius add button --to ./src/MyApp --namespace MyApp.Ui

That's it: <ZitsButton /> is now yours. Browse the components.
