Install

1. Install the theme package to your project with your preferred package manager:

   npm install toolbeam-docs-theme @fontsource/ibm-plex-mono

   Optionally, install packages for linked headings.

   npm install @astrojs/markdown-remark rehype-autolink-headings

2. Add the theme to your Starlight config.

   astro.config.mjs

   import theme from "toolbeam-docs-theme";
   import { rehypeHeadingIds } from "@astrojs/markdown-remark";
   import rehypeAutolinkHeadings from "rehype-autolink-headings";
   
   export default defineConfig({
     // ...
     integrations: [
       starlight({
         // ...
         plugins: [theme()],
       }),
     ],
    // Optional, linked headings
    markdown: {
      rehypePlugins: [
        rehypeHeadingIds,
        [rehypeAutolinkHeadings, { behavior: "wrap" }],
      ],
    },
   });
