 ## User Feedback
 
-On user-facing platforms such as mobile or the browser this means first class support for requesting user feedback when an error occurs.
+For all SDKs, it is strongly recommended to send the `User Feedback` as an [envelope](/sdk/envelopes/#user-feedback). Alternatively, the SDKs can
+use the [User Feedback endpoint](https://docs.sentry.io/api/projects/submit-user-feedback/), which is not recommended.
 
-On backend platforms, SDKs should document how to use the last event ID to prompt the user for feedback themselves.
+### User Facing Platforms
+On user-facing platforms such as mobile, desktop, or browser this means first-class support for requesting User Feedback when an error or crash occurs.
+To see some examples of the API check out the user-facing docs for [Apple](https://docs.sentry.io/platforms/apple/enriching-events/user-feedback/) and
+[Java](https://docs.sentry.io/platforms/java/enriching-events/user-feedback/).
+
+On mobile and desktop, it is common to prompt the user for feedback after a crash happened on the previous run of the application. Therefore the SDKs should
+implement the `onCrashedLastRun` callback on the options. This callback gets called shortly after the initialization of the SDK when the last program execution
+terminated with a crash. The SDK should execute the callback only once during the entire run of the program to avoid multiple callbacks if there are multiple 
+crash events to send.
+
+### Backend Platforms
+
+On backend platforms, SDKs should document how to use the [last event ID](#retrieve-last-event-id) to prompt the user for feedback themselves. 
+
+### Example implementations
+
+User Feedback class:
+ * [Objective-C](https://github.com/getsentry/sentry-cocoa/blob/9eedc425727f0daccca1bd2be6021f6c3d9c654c/Sources/Sentry/SentryUserFeedback.m)
+ * [Java](https://github.com/getsentry/sentry-java/blob/671f9e0b8b709ef18e8b0788c31df44f99d09d35/sentry/src/main/java/io/sentry/UserFeedback.java#L7)

+Envelope item:

+ * [Objective-C](https://github.com/getsentry/sentry-cocoa/blob/fd3e46efe59324e894d5601a7b3028824a588dda/Sources/Sentry/SentryEnvelope.m#L145-L162)
