+# Starlight Docs Grammars
+
+This directory contains additional grammars for the Starlight documentation website.
+
+## Grammars
+
+The following additional grammars are generated and available for use:
+
+- [Markdoc](https://github.com/markdoc/language-server)
+
+## Usage
+
+To generate the grammars from their source files, run:
+
+```sh
+pnpm grammars
+```
+
+To include the grammars in the Starlight documentation website, update the `expressiveCode.shiki.langs` array in the `astro.config.mjs` file:
+
+```diff
+starlight({
+  expressiveCode: {
+    shiki: {
+      langs: [
+        JSON.parse(
+          fs.readFileSync('./grammars/existing.tmLanguage.json', 'utf-8'),
++         fs.readFileSync('./grammars/new.tmLanguage.json', 'utf-8'),
+        ),
+      ],
+    },
+  },
+});
+```
