Size limits for attachments are now at 100MB. Additionally, this PR adds
more information on size limits to the Native SDK and Attachments page.

 To receive symbolicated stack traces, you have to upload debug information to Sentry. Unless the option to store crash reports is enabled, Sentry will use the crash reports only to create the event, then will drop the files. For more information, see [Debug Information Files](/workflow/debug-files/).
 
+## Size Limits
+
+Sentry allows at most 100MB of attachments per event, including the crash report file. Uploads exceeding this size are rejected with HTTP error `413 Payload Too Large` and the data is dropped immediately. To add larger or more files, consider secondary storage options.
+
+Usually, native crash reports range from a few kilobytes to a few megabytes. This leaves sufficient space to add custom attachments. In case your application generates particularly large crash reports, consider to limit or avoid adding additional attachments in the SDK.
+
 ## Storage and Quota Impact
 
 Attachments persist for 30 days; if your total storage included in your quota is exceeded, attachments will not be stored. You can delete attachments or their containing events at any time. Deleting an attachment does not affect your quota - Sentry counts an attachment toward your quota as soon as it is stored.

+### Application Crashes
+
+By default, the Native SDK intercepts crash signals and unhandled exceptions to
+send crash reports to Sentry. Depending on the [backend](#integrations), the
+crash report can be sent as a conventional event or as a native crash report
+file. On Windows, Linux, and macOS, the default backends send binary Minidump
+files. Sentry processes them to extract stack traces and exception information
+into a readable crash report.
+
+For more information on Minidumps and the limits that apply, see
+[What is a Minidump](/platforms/native/minidumps#what-is-a-minidump).
+
+{% capture __alert_content -%}
+The size of Minidumps can vary between a few kilobytes and many megabytes.
+Contributing factors are the number of threads, size of stack space, and the
+number of heap memory regions referenced from the stack. As Minidumps often
+contain large regions of empty memory, the SDK compresses Minidumps before
+uploading. Sentry drops requests with a body larger than _20MB_, or if they
+contain files larger than _100MB_.
