 Install `sentry-sdk` from PyPI with the `falcon` extra:
 
 ```bash
-pip install --upgrade 'sentry-sdk[falcon]==0.16.2'
+pip install --upgrade 'sentry-sdk[falcon]'
 ```
 
 ## Configure
 
-To configure the SDK, initialize it with the integration before your app has been initialized:
+If you have the `falcon` package in your dependencies, the Falcon integration will be enabled automatically when you initialize the Sentry SDK.
 
 <SignInNote />
 
 ```python
 import falcon
+
 import sentry_sdk
-from sentry_sdk.integrations.falcon import FalconIntegration
 
 sentry_sdk.init(
     dsn="___PUBLIC_DSN___",
-    integrations=[

     # Set traces_sample_rate to 1.0 to capture 100%
     # of transactions for performance monitoring.

+import falcon

+    def on_get(self, req, resp):

+        1 / 0  # raises an error
+        resp.media = message

+app = falcon.App()
+app.add_route('/', HelloWorldResource())
+```
+
+When you point your browser to [http://localhost:8000/](http://localhost:8000/) a transaction will be created in the Performance section of [sentry.io](https://sentry.io). Additionally, an error event will be sent to [sentry.io](https://sentry.io) and will be connected to the transaction.
+
+It takes a couple of moments for the data to appear in [sentry.io](https://sentry.io).

 ## Behavior
 
 - The Sentry Python SDK will install the Falcon integration for all of your apps. The integration hooks into the base `falcon.API` class via monkey patching.
