<title>Introduction</title>
<para>This book is the official Guacamole manual, written by the upstream developers of the
Guacamole project. It is also the official general documentation, and an online version
at <link xlink:href="http://guac-dev.org/">http://guac-dev.org/</link>. It is a work in
progress which will be continuously updated as Guacamole changes with each
release.</para>
<para>We decided to maintain the documentation for Guacamole as a book, as there is an awful
lot that can be done with the Guacamole web application, and even more that can be done
with the API. This book is intended to explore the possibilities of Guacamole as an
application, and to provide documentation necessary to install, maintain, and use
Guacamole.</para>
<para>For the sake of users and administrators, we have provided a
high-level overview of Guacamole's architecture and technical
design, as well as basic usage instructions and installation
instructions for common platforms.</para>
<para>For the sake of developers, we have provided a protocol reference
and tutorials for common tasks (implementing protocol support,
integrating Guacamole into your own application, etc.) to give a
good starting point beyond simply looking at the Guacamole
codebase.</para>
<para>This particular edition of the <citetitle>Guacamole Manual</citetitle> covers
Guacamole version 0.9.0. New releases which create new features or break compatibility
will result in new editions of the user's guide, as will any necessary corrections. As
the official documentation for the project, this book will always be freely available in
its entirety online.</para>

<para>Guacamole is an HTML5 web application that provides access to desktop environments
using remote desktop protocols (such as VNC or RDP). Guacamole is also the project
that produces this web application, and provides an API that drives it. This API can
be used to power other similar applications or services.</para>
<para>"Guacamole" is most commonly used to refer to the web application produced by the
Guacamole project using their API. This web application is part of a stack that
provides a protocol-agnostic remote desktop gateway. Written in JavaScript and using
only HTML5 and other standards, the client part of Guacamole requires nothing more
than a modern web browser or web-enabled device when accessing any of the desktops
served.</para>

<primary>RealMint</primary>
</indexterm>
<para>Historically, Guacamole was an HTML5 VNC client, and before that, a JavaScript
Telnet client called <application
xlink:href="http://sourceforge.net/projects/realmint">RealMint</application>
("RealMint" is an anagram for "terminal"), but this is no longer the case.
Guacamole's architecture has grown to encompass remote desktop in general, and can
be used as a gateway for any number of computers. Originally a proof-of-concept,
Guacamole is now performant enough for daily use, and all Guacamole development is
done over Guacamole.</para>
<para>As an API, Guacamole provides a common and efficient means of streaming text data
over a JavaScript-based tunnel (which need not use WebSocket), and a client
implementation which supports the Guacamole protocol and renders the remote display
when combined with a Guacamole protocol stream from the tunnel.</para>
<para>It provides cross-browser mouse and keyboard events, an XML-driven on-screen
keyboard, and synchronized nestable layers with hardware-accelerated compositing.
Projects that wish to provide remote desktop support over HTML5 can leverage the
years of research and development that went into Guacamole by incorporating the API
into their application or service.</para>

<title>Why use Guacamole?</title>
<para>The principle reason to use Guacamole is constant, world-wide, unfettered access
to your computers.</para>
<para>Guacamole allows access one or more desktops from anywhere remotely, without
having to install a client, particularly when installing a client is not possible.
By setting up a Guacamole server, you can provide access to any other computer on
the network from virtually any other computer on the internet, anywhere in the
world. Even mobile phones or tablets can be used, without having to install
anything.</para>
<para>As a true web application whose communication is over HTTP or HTTPS only,
Guacamole allows you to access your machines from anywhere without violating the
policy of your workplace, and without requiring the installation of special clients.
The presence of a proxy or corporate firewall does not prevent Guacamole use.</para>

<simplesect xml:id="access-from-anything" xmlns:xl="http://www.w3.org/1999/xlink">
<title>Access your computers from any device</title>
<para>As Guacamole requires only a reasonably-fast, standards-compliant browser,
Guacamole will run on many devices, including mobile phones and tablets.</para>
<para>Guacamole is specifically designed to not care whether you have a mouse, keyboard,
touchscreen, or any combination of those.</para>
<para>One of the major design philosophies behind Guacamole is that it should never
assume you have a particular device (ie: a mobile phone) just because your browser
has or is missing a specific feature (ie: touch events or a smallish screen).
Guacamole's codebase provides support for both mouse and touch events
simultaneously, without choosing one over the other, while the interface is intended
to be usable regardless of screen size.</para>
<para>Barring bugs, you should be able to use Guacamole on just about any modern device
with a web browser.</para>

<simplesect xml:id="non-physical-computer" xmlns:xl="http://www.w3.org/1999/xlink">
<title>Keep a computer in the "cloud"</title>
<para>Ignoring the buzzword, it's often useful to have a computer that has no dedicated
physical hardware, where its processing and storage power are handled transparently
by redundant systems in some remote datacenter.</para>
<para>Computers hosted on virtualized hardware are more resilient to failures, and with
so many companies now offering on-demand computing resources, Guacamole is a perfect
way to access several machines that are only accessible over the internet.</para>
<para>In fact, all Guacamole development is done on computers like this. This is partly
because we like the mobility, and partly because we want to ensure Guacamole is
always performant enough for daily use.</para>
</simplesect>
<simplesect xml:id="group-access" xmlns:xl="http://www.w3.org/1999/xlink">
<title>Provide easy access to a group</title>
<para>Guacamole allows you to centralize access to a large group of machines, and
specify on a per-user basis which machines are accessible. Rather than remember a
list of machines and credentials, users need only log into a central server and
click on one of the connections listed.</para>
<para>If you have multiple computers which you would like to access remotely, or you are
part of a group where each person has a set of machines that they need remote access
to, Guacamole is a good way to provide that access while also ensuring that access
is available from anywhere.</para>

<simplesect xml:id="adding-remote-access" xmlns:xl="http://www.w3.org/1999/xlink">
<title>Adding HTML5 remote access to your existing infrastructure</title>
<para>As Guacamole is an API, not just a web application, the core components and
libraries provided by the Guacamole project can be used to add HTML5 remote access
features to an existing application. You need not use the main Guacamole web
application; you can write (or integrate with) your own rather easily.</para>
<para>If you host an on-demand computing service, adding HTML5-based remote access
allows users of your service more broad access; users need nothing more than a web
browser to see their computers' screens.</para>
