+# 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.
+
+    (EE)

+
+## 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.
+(EE) 8: /usr/bin/Xvnc (0x400000+0x13e674) [**0x53e674**]
+
+    echo info line ***0x53eaaa** | gdb -q /usr/bin/Xkasmvnc
+    (gdb) Line 223 of "/src/common/network/webudp/Wu.cpp" starts at address 0x53e674 <WuClientSendPendingDTLS(WuClient*, Wu const*, Wu const*)+68>
+
+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
+    done
+
+Using this script on the above example backtrace produces the following output.

 # KasmVNC - Linux Web Remote Desktop
 
-[![Kasm Technologies](https://kasm-static-content.s3.amazonaws.com/368_kasm_logo_.jpg "Kasm Logo")](https://kasmweb.com)
+<a href="https://kasmweb.com"><img src="https://kasm-static-content.s3.amazonaws.com/logo_kasm.png" width="300"><a/>
 
-[Kasm Technologies LLC](https://www.kasmweb.com) developed Kasm Server, a Containerized Desktop Infrastructure (CDI) solution. Kasm started with TigerVNC and eventually forked it to create KasmVNC. KasmVNC is used within the overal Kasm CDI infrastructure, however, you can use KasmVNC for individual servers. KasmVNC has different goals than TigerVNC:
+KasmVNC provides remote web-based access to a Desktop or application. While VNC is in the name, KasmVNC differs from other VNC variants such as TigerVNC, RealVNC, and TurboVNC. KasmVNC has broken from the RFB specification which defines VNC, in order to support modern technologies and increase security. KasmVNC is accessed by users from any modern browser and does not support legacy VNC viewer applications. KasmVNC uses a modern YAML based configuration at the server and user level, allowing for ease of management.
+
+[Kasm Technologies](https://www.kasmweb.com) developed Kasm Workspaces, the Containerized Streaming Platform. Kasm has open-sourced the Workspace docker images, which include containerized [full desktops and apps](https://github.com/kasmtech/workspaces-images) and [base images](https://github.com/kasmtech/workspaces-core-images) intended for developers to create custimized streaming containers. These containers can be used standalone or within the [Kasm Workspaces Platform](https://www.kasmweb.com) which provides a full Enterprise feature set.
+
+## Documentation
+
+**Do not use the README from the master branch**, unless you are compiling KasmVNC yourself from the tip of master. Use the documentation for your specific release.
+
+  - [KasmVNC 1.0.0 Documentation](https://www.kasmweb.com/kasmvnc/docs/1.0.0/index.html)
+
+  For beta releases prior to version 1.0.0, use the README in this github project on the tagged commit for that release.
+
+## Installation
+
+**You must disconnect and reconnect to the server after installation, for the group membership to apply.**
+
+### Debian/Ubuntu/Kali
+```sh
+# Please choose the package for your distro here (under Assets):
+# https://github.com/kasmtech/KasmVNC/releases
+wget <package_url>
+
+sudo apt-get install ./kasmvncserver_*.deb
+
+# Add your user to the ssl-cert group
+sudo addgroup $USER ssl-cert
+```
+
+### Oracle 8
+```sh
+# Please choose the package for your distro here (under Assets):
+# https://github.com/kasmtech/KasmVNC/releases
+wget <package_url>
+
+# Ensure KasmVNC dependencies are available
+sudo dnf config-manager --set-enabled ol8_codeready_builder
+sudo dnf install oracle-epel-release-el8
+
+sudo dnf localinstall ./kasmvncserver_*.rpm
+
+# Add your user to the kasmvnc-cert group
+sudo usermod -a -G kasmvnc-cert $USER
+```
+
+### CentOS 7
+
+```sh
+# Please choose the package for your distro here (under Assets):
+# https://github.com/kasmtech/KasmVNC/releases
+wget <package_url>
+
+# Ensure KasmVNC dependencies are available
+sudo yum install epel-release
+
+sudo yum install ./kasmvncserver_*.rpm
+
+# Add your user to the kasmvnc-cert group
+sudo usermod -a -G kasmvnc-cert $USER
+```
+
+## Getting Started
+
+The following examples provide basic usage of KasmVNC with the tools provided. For full documentation on all the utilities and the runtime environment, see our [KasmVNC Documentation](https://www.kasmweb.com/kasmvnc/docs/latest/index.html)
+
+```sh
+# Start a session and be guided to setup a user and select a default desktop environment
+vncserver
+
+# Start a session with the mate desktop environment
+vncserver -select-de mate
+
+# Add a new user with read/write permissions
+vncpasswd -u my_username -w -r
+
+# Tail the logs
+tail -f ~/.vnc/*.log
+
+# Get a list of current sessions with display IDs
+vncserver -list
+
+# Kill the VNC session with display ID :2
+vncserver -kill :2
+```
+
+## Configuration
+
+KasmVNC is configured via YAML based configurations. The server level configuration is at `/etc/kasmvnc/kasmvnc.yaml`. Edits to this file apply to all users. Individual users can override server global configurations by specifying them in their configuration file at `~/.vnc/kasmvnc.yaml`.
+
+The following configuration shows all default settings. Many of the encoding settings can be overridden by the client, unless the `runtime_configuration.allow_client_to_override_kasm_server_settings` setting is set tot false. By default the client is allowed to modify encoding settings.
+
+For a full description of each setting see the [configuration reference](https://www.kasmweb/kasmvnc/docs/latest/index.html).

-  - Web-based - KasmVNC is designed to provide a web accessible remote desktop. It comes with a web server and websocket 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 suffecient 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.

-### Installation
-
-#### Debian-based
-
-```sh
-wget -qO- https://github.com/kasmtech/KasmVNC/releases/download/v0.9.1-beta/kasmvncserver_0.9.1~beta-1_amd64.deb
-
-sudo dpkg -i kasmvncserver_0.9.1~beta-1_amd64.deb
-sudo apt-get -f install
-
-# We provide an example script to run KasmVNC at #
-# /usr/share/doc/kasmvncserver/examples/kasmvncserver-easy-start. It runs a VNC
-# server on display :10 and on interface 0.0.0.0. If you're happy with those
-# defaults you can just use it as is:
-sudo ln -s /usr/share/doc/kasmvncserver/examples/kasmvncserver-easy-start /usr/bin/
-
-# Add your user to the ssl-cert group
-sudo addgroup $USER ssl-cert
-# You will need to re-connect in order to pick up the group change
-
-# Create ~/.vnc directory and corresponding files.
-kasmvncserver-easy-start -d && kasmvncserver-easy-start -kill
-
-# Modify vncstartup to launch your environment of choice, in this example LXDE
-# This may be optional depending on your system configuration
-echo '/usr/bin/lxsession -s LXDE &' >> ~/.vnc/xstartup
-
-# Start KasmVNC with debug logging:
-kasmvncserver-easy-start -d
-
-# Tail the logs
-tail -f ~/.vnc/`hostname`:10.log
-```
-
-Now navigate to your system at https://[ip-address]:8443/
-
-To stop a running KasmVNC:
-
-```sh
-kasmvncserver-easy-start -kill
-```
-
-The options for vncserver:
-
-| Argument | Description |
-| -------- | ----------- |
-| depth | Color depth, for jpeg/webp should be 24bit |
-| geometry | Screensize, this will automatically be adjusted when the client connects. |
-| websocketPort | The port to use for the web socket. Use a high port to avoid having to run as root. |
-| cert | SSL cert to use for HTTPS |
-| sslOnly | Disable HTTP |
-| interface | Which interface to bind the web server to. |
-
-### Development
-Would you like to contribute to KasmVNC? Please reachout to us at info@kasmweb.com
-
-We need help, especially in packaging KasmVNC for various operating systems. We would love to have standard debian or RMP packages and host our own repo, however, that all requires a lot of experience, proper testing, and pipeline development for automated builds.
-
-We also need help with Windows, which is not currently supported. While KasmVNC can technically be built for Windows 10, it is unusably slow, due to all the changes that occured in Windows since the original Windows support was added in the chain of VNC forked projects.

+# Preparing a release
+
+Deb and rpm packages need their versions bumped to the new release version. It
+can be done with:
+
+```
+builder/bump-package-version 0.9.4-beta
+```
+
+This will update corresponding package files, use `git diff` to see changes.
+
+If you've ran the command and curious about Debian version specifics, here's an
+explanation:
+Deb version will be `0.9.4~beta-1`. `~` (and not `-`) is required by packaging
+guidelines, and `-1` is Debian package revision for `0.9.4` upstream release. If
+a Debian-specific patch was later added on top of `0.9.4`, it'd be `-2` for the
+next Debian version. Rpm has a corresponding revision in its .spec file.

+## Building a Ubuntu Focal package

+You don't need to `build-package` every time you change something, but you need

+
+## Running a development environment
+
+```
+builder/devenv-vncserver
+```
+
+`devenv-vncserver` starts a dockerized development environment. Edit
+`vncserver`, its modules, and configuration files as usual. When you
+run`vncserver`, not `/usr/bin/vncserver` will be used, but `./unix/vncserver`.
+Same for configuration files.
+
+Python specs can be run with `ty` alias inside devenv.
+
+### Debug output
+To see `vncserver` output, run `ty -d`. Anything you print inside `vncserver`
+with `say` should be visible that way.
+
+### Finding which spec produces a warning
+By default, each passing test is represented as a dot. `-v` flag causes tests to
+emit test descriptions alongside the program's output. Run `ty -v`.
+
+# ARM
+
+KasmVNC is supported on ARM, however, the build process needs to be broken into two parts with one occuring on a x64 system and the other on an ARM system. All our testing and official builds are done on AWS Graviton instances.
+
+### Build www code on x86 System
+The www code is webpacked for performance and thus requires building. There are NPM packages, phantomjs, which do not have an ARM build. Therefore, this must be built on x86 and then copied over to the ARM system for final packaging.
+
+```
+cd ~/KasmVNC
+mkdir builder/www
+sudo docker build -t kasmweb/www -f builder/dockerfile.www.build .
+sudo docker run --rm -v $PWD/builder/www:/build kasmweb/www:latest
+cd builder
+tar -zcvf /tmp/kasm_www.tar.gz www
+```
+
+Now transfer ```kasm_www.tar.gz``` to the ARM system.
+
+### Build KasmVNC ARM
+These instructions assume KasmVNC has been cloned at $HOME and ```kasm_www.tar.gz``` has been placed at $HOME as well, adjust for your environment.
+
+```
+cd ~
+tar -zxf kasm_www.tar.gz -C KasmVNC/builder/
+cd KasmVNC
+sudo builder/build-package ubuntu bionic
+```
+The resulting deb package can be found under ~/KasmVNC/builder/build/bionic
+Replace ```bionic``` with ```focal``` to build for Ubuntu 20.04LTS. At this time, only Ubuntu Bionic has been tested, however, other Debian based builds we support should also work.

 %description
-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 provides remote web-based access to a Desktop or application. 
+While VNC is in the name, KasmVNC differs from other VNC variants such 
+as TigerVNC, RealVNC, and TurboVNC. KasmVNC has broken from the RFB 
+specification which defines VNC, in order to support modern technologies 
+and increase security. KasmVNC is accessed by users from any modern 
+browser and does not support legacy VNC viewer applications. KasmVNC 
+uses a modern YAML based configuration at the server and user level, 
+allowing for ease of management. KasmVNC is maintained by Kasm 
+Technologies Corp, www.kasmweb.com.
 
-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.
