+# Debugging
+In the case where KasmVNC crashes and a backtrace is produced. Developers need a way to make the backtrace useful for debugging. This document covers where the backtrace is logged and how to use a debug symbol package and gdb to gain more information from the backtrace, such as filename, function name, and line number.
+
+## Test Symbolization
+If you want to induce a crash to test that you can symbolize a backtrace you can start KasmVNC and then issue the following command.
+
+    killall -SEGV Xvnc
+
+This will cause KasmVNC to terminate with a backtrace similar to the following. You will find the backtrace in the log file at $HOME/.vnc/$HOSTNAME:$DISPLAY.log where HOME is your user's profile path, HOSTNAME is the hostname of the system, and DISPLAY is the assigned display number for the session.
+

+
+## Debug Symbol Package
+In order to make use of this backtrace, you will need to symbolize the backtrace. Each build of KasmVNC produced by our pipelines comes with a corresponding debug symbol package that can be downloaded. You need two pieces of information to get the package, the git commit ID of KasmVNC and the MD5 sum of Xkasmvnc binary on your system. 
+
+The git commit ID can be found using Xvnc -version:
+
+    ubuntu@matt-dev-vm-1:~$ Xvnc -version
+    Xvnc KasmVNC 0.9.94002f39917dca0ad82ac0c29a75c723b538b32b - built Feb 17 2022 15:21:01
+    Copyright (C) 1999-2018 KasmVNC Team and many others (see README.me)
+    See http://kasmweb.com for information on KasmVNC.
+    Underlying X server release 12010000, The X.Org Foundation
+
+The MD5 sum can be obtained using the md5sum command:
+
+    md5sum /usr/bin/Xkasmvnc
+    57ee7028239c5a737c0aeee4a34138c3  /usr/bin/Xkasmvnc
+    
+With these two pieces of information, you can get the debug symbol package at https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/[COMMITID]/[MD5SUM]/kasmvncserver-dbgsym.deb, in the above example it would be.

+
+## Symbolize a Backtrace
+With the KasmVNC binary and debug symbol package installed on the system, you can use gdb or addr2line to get more information, such as the filename, function name, and line number that the backtrace line is referring to. 
+
+Here is a single line from a backtrace. The following example shows how to retrieve additional information that can help with debugging the crash.

+
+The following script will search the provide file for a backtrace and symbolize the entire backtrace.
+
+    #!/bin/bash
+      
+    FILENAME=$1
+    grep "(EE)" $FILENAME | while read -r line ; do
+            BACKTRACE=$(echo $line | grep -Po '\[[0-9a-f]x[a-f0-9]{1,}' | sed -r 's#\[##')
+            echo $line
+            if ! [ -z $BACKTRACE ] ; then
+                    SYMBOLIZED=$(echo "info line *${BACKTRACE}" | gdb /usr/bin/Xkasmvnc | grep "(gdb)" | grep -vP "\(gdb\)\s*quit$")
+                    echo "    ${SYMBOLIZED}"
+            fi

   - Security - The RFB specification (VNC) limits the password field to 8 characters, so while the client may take a longer password, only the first 8 characters are sent. KasmVNC defaults to HTTPS with HTTP Basic Auth and disables the legacy VNC authentication method which is not sufficiently secure for internet accessible systems.
   - Simplicity - KasmVNC aims at being simple to deploy and configure.
 
+# Releases
+
+Since this is a fast evolving project, the documents on the tip of master are chaning rapidly and will not match releases. Be sure to use the README and other documentation from the release branch that matches the version of KasmVNC you are using. Do not use the README from the master branch, unless you are compiling KasmVNC yourself from the tip of master. All releases starting at 0.9.3 have a branch named in the format 'release/0.9.3', for example.

+VNC stands for Virtual Network Computing. It is, in essence, a remote
+display system which allows you to view a computing `desktop' environment
+not only on the machine where it is running, but from anywhere on the
+Internet and from a wide variety of machine architectures.
+
+KasmVNC has different goals than TigerVNC:
+
+Web-based - KasmVNC is designed to provide a web accessible remote desktop.
+It comes with a web server and web-socket server built in. There is no need to
+install other components. Simply run and navigate to your desktop's URL on the
+port you specify. While you can still tun on the legacy VNC port, it is
+disabled by default.
+
+Security - KasmVNC defaults to HTTPS and allows for HTTP Basic Auth. VNC
+Password authentication is limited by specification to 8 characters and is not
+sufficient for use on an internet accessible remote desktop. Our goal is to
+create a by default secure, web based experience.
+
+Simplicity - KasmVNC aims at being simple to deploy and configure.

+.SH NAME
+kasmxproxy \- proxy an existing X11 display to a KasmVNC display
+.SH SYNOPSIS
+.B kasmxproxy
+.RB [ \-a|\-\-app\-display
+.IR source\-display ]
+.RB [ \-v|\-\-vnc\-display
+.IR destination\-display ]
+.RB [ \-f|\-\-fps
+.IR FPS ]
+.RB [ \-r|\-\-resize ]
+.br
+
+.SH DESCRIPTION
+.B kasmxproxy
+is used to proxy an x display, usually attached to a physical GPU, to KasmVNC display. This is usually used in the context of providing GPU acceleration to a KasmVNC session.
+
+.SH OPTIONS
+.TP
+.B \-a, \-\-app\-display \fIsource-display\fP
+Existing X display to proxy.
+Defaults to :0.
+
+.TP
+.B \-v, \-\-vnc\-display \fIdestination-display\fP
+X display, where source display will be available on.
+Defaults to :1.
+
+.TP
+.B \-f, \-\-fps \fIframes-per-second\fP
+X display, where the source display will be available on.
+Defaults to 30 frames per second.
+
+.TP
+.B \-r|\-\-resize
+Enable resizing. WARNING: DO NOT ENABLE IF PHYSICAL DISPLAY IS ATTACHED.
+Disabled by default.
+
+.SH EXAMPLES
+.TP
+.BI "kasmxproxy -a :1 -v :10 -r"
+.B  Proxy display :1 to display :10, with resizing on.
