 ### Using Hooks
 
@@ -193,6 +195,17 @@ Be aware that the client will still save the key to the browser's local storage
 
 On a normal client you will only ever need to handle local storage keys called `p` (profile), `g` (game settings), `s` (server list), `r` (shared world relays), in your hooks functions. Feel free to just ignore any other keys. It is guaranteed that the data the client stores will always be valid base64, so it is best practice to decode it to raw binary first if possible to reduce it's size before saving it to something like a MySQL database in your backend if you are trying to implement some kind of profile syncing system for your website. The keys already have GZIP compression applied to them by default so don't bother trying to compress them yourself a second time because it won't reduce their size.
 
+### Crash Report Hook
+
+The `crashReportShow` hook can be used to capture crash reports and append additional text to them. It takes two parameters, the crash report as a string and a callback function for appending text. Do not use the callback function outside the body of the hook.
+
+    hooks: {
+        crashReportShow: function(report, customMessageCB) {
+            // 'report' is crash report as a string
+            customMessageCB("Hello from crashReportShow hook!");
+        }
+    }

 ## Developing a Client
 
 There is currently no system in place to make forks of 1.8 and merge commits made to the patch files in this repository with the patch files or workspace of the fork, you're on your own if you try to keep a fork of this repo for reasons other than to contribute to it
