 instance.
 
+### NestJS
+
+Requires the Express platform (`@nestjs/platform-express`, Nest's default) — it wraps the
+`cache-viewer/express` middleware and registers it via `configure()`, so it's mounted as part
+of the module graph instead of touching `main.ts`.
+
+```ts
+import { Module } from "@nestjs/common";
+import { caching } from "cache-manager";
+import { fromCacheManager } from "cache-viewer";
+import { CacheViewerModule } from "cache-viewer/nestjs";
+
+const cache = await caching("memory", { max: 1000, ttl: 60_000 });
+
+@Module({
+  imports: [CacheViewerModule.forRoot("/cache-ui", { adapter: fromCacheManager(cache) })],
+})
+export class AppModule {}

+`CacheViewerOptions` (`adapter`, `enabled`, `auth`) are the same as the Express binding — see
+[Auth](#auth) below.
