+## Search-only Client for Browser
+You can create a search-only client instance for use in the browser by importing the `SearchClient` class from `typesense/dist`.
+
+```typescript
+import { SearchClient } from 'typesense/dist'
+
+const client = new SearchClient({
+  nodes: [
+    {
+      host: 'localhost',
+      port: '8108',
+      protocol: 'http',
+    },
+    ],
+    apiKey: 'xyz',
+    connectionTimeoutSeconds: 2,
+    healthcheckIntervalSeconds: 60,
+
+})
+```

 ### Examples
 
 Here are some examples with inline comments that walk you through how to use the client: [doc/examples](doc/examples)
