 Environments tell you where an error occurred, whether that's in your production system, your staging server, or elsewhere.
+It help you better filter issues, releases, and user feedback in the Issue Details page of sentry.io, which you learn more about in our [documentation that covers using environments](/product/sentry-basics/environments/).
 
 Sentry automatically creates an environment when it receives an event with the `environment` parameter set.
 
-Environments are case-sensitive. The environment name can't contain newlines, spaces or forward slashes, can't be the string "None", or exceed 64 characters. You can't delete environments, but you can [hide](/product/sentry-basics/environments/#hidden-environments) them.
+By default, the SDK reports `Editor` when running inside the Unreal Engine Editor. 
+For shipping builds it'll use `Release` and in other configurations it'll use `FApp::GetBuildConfiguration()`
+You can also set the default environment to `Release`, `Development`, or `Debug` in your build configuration or override the environment value programatically.
