+## Using ngrok
+
+The development server can be operated behind ngrok for when you need to receive traffic from the outside world. This comes up frequently when working with integrations. Start off by defining a configuration file for `ngrok`:
+
+```yaml
+version: '2'
+authtoken: <YOUR-NGROK-AUTHTOKEN>
+tunnels:
+  acme-org
+    proto: http
+    hostname: $yourname.ngrok.dev
+    addr: 8010
+    host_header: 'rewrite'
+```
+
+Next start up ngrok with your configuration file:
+
+```shell
+ngrok start --all --config ngrok.yml`
+```
+
+When starting devserver provide your ngrok domain
+
+```shell
+sentry devserver --ngrok=$yourname.ngrok.dev
+```

+This setup will result in both the region and control servers responding to different domains. The multi-region setup with ngrok also enables customer-domains and you'll need ngrok domains for each organization you plan on using. In this configuration, CORS will work similar to production.
