 # Vite-Plugin-Hyperstyles
 
-A Vite plugin that allows you to use styled hyperscript easily.
+A Vite plugin that allows you to easily style your hyperscript using
+module-scoped CSS.
+
+## Usage
+
+```css
+/* styles.modules.css */
+.container {
+  display: flex;
+  flex-direction: column;
+  align-items: center;
+}
+
+.title {
+  color: blue;
+  font-size: 20px;
+}
+
+.description {
+  color: gray;
+  font-size: 16px;
+}
+```
+
+```typescript
+import h from "./styles.modules.css";
+
+// Class name scopes are applied automatically
+const element = h("div.container", [
+  h("h1.title", "Hello, World!"),
+  h(
+    "p.description",
+    { className: h.description },
+    "This is a styled hyperscript example.",
+  ),
+]);
+```
+
+This replaces the slightly more verbose syntax that can be used without the
+plugin:
+
+```typescript
+import hyper from "@macrostrat/hyper";
+import styles from "./styles.modules.css";
+
+const h = hyper.styled(styles);
+...
+```
+
+## Configuration
+
+In your `vite.config.ts`, add the plugin:
+
+```typescript
+import { defineConfig } from "vite";
+import hyperStyles from "@macrostrat/vite-plugin-hyperstyles";
+
+export default defineConfig({
+  plugins: [hyperStyles()],
+});
+```
+
+If you're using Typescript, you'll want to add a type declaration for the
+enhanced hyperscript function to your TSConfig
+
+```json
+{
+  "compilerOptions": {
+    // ...
+    "types": ["@macrostrat/vite-plugin-hyperstyles/client", "vite/client"]
+    // Note: order matters; ensure vite/client comes after this plugin
+  }
+}
+```
