 Either pass the `endpoint` option, or set the `SEAM_ENDPOINT` environment variable.
 
+#### Setting the request timeout
+
+Requests time out after 30 seconds by default.
+Pass the `timeout` option, in seconds, to override this:
+
+```ruby
+seam = Seam.new(api_key: "your-api-key", timeout: 60)
+```
+
+The value sets both the Faraday `timeout` and `open_timeout`.
+Either may be set independently via `faraday_options`, which takes precedence:
+
+```ruby
+seam = Seam.new(
+  api_key: "your-api-key",
+  faraday_options: {request: {timeout: 60, open_timeout: 5}}
+)
+```
+
+A request that exceeds the timeout raises `Faraday::TimeoutError`.

 #### Configuring the Faraday Client
 
 The Faraday client and retry behavior may be configured with custom initiation options
