+# @hunk/session-broker-bun
+
+Bun HTTP and websocket adapter for `@hunk/session-broker`.
+
+Use this package when you want to serve a runtime-neutral `SessionBrokerDaemon` through `Bun.serve(...)`.
+
+## What it does
+
+- binds a broker daemon to a Bun HTTP server
+- upgrades websocket requests on the daemon socket path
+- forwards websocket messages and close events into the daemon
+- exposes a `stopped` promise compatible with Hunk's daemon lifecycle
+- lets callers override or add custom HTTP routes before the generic broker routes
+
+## Usage
+
+```ts
+import { SessionBroker, createSessionBrokerDaemon } from "@hunk/session-broker";
+import { serveSessionBrokerDaemon } from "@hunk/session-broker-bun";
+
+const broker = new SessionBroker({
+  parseRegistration,
+  parseSnapshot,
+});
+
+const daemon = createSessionBrokerDaemon({
+  broker,
+  capabilities: { version: 1, name: "example-broker" },
+});
+
+const server = serveSessionBrokerDaemon({
+  daemon,
+  hostname: "127.0.0.1",
+  port: 47657,
+});
+```
+
+## Custom routes
+
+You can override or extend request handling with `handleRequest`.
+
+```ts
+const server = serveSessionBrokerDaemon({
+  daemon,
+  hostname: "127.0.0.1",
+  port: 47657,
+  handleRequest: async (request) => {
+    const url = new URL(request.url);
+    if (url.pathname === "/health") {
+      return Response.json({ ok: true, overridden: true });
+    }
+
+    return undefined;
+  },
+});
+```
+
+Return `undefined` to fall through to the generic broker routes.
