+\startdocument[graphic=1]
+
+\startbuffer[1]
+    There are several ways to deploy \CONTEXT. Most common is to let it render a
+    document, in which case you install it on a system and use an editor to input
+    your document and from a console or by clicking some key trigger a run. The
+    input can be structured using \TEX\ macros but it can also be \XML, or some
+    other format that gets converted to \CONTEXT\ commands before processing.
+\stopbuffer
+
+\startbuffer[2]
+    Instead you can also use \CONTEXT\ as a more hidden application, for instance
+    in a web service or rendering component in a larger application. In that case
+    the end user is not really aware that \TEX\ is being used.
+\stopbuffer
+
+\startbuffer[3]
+    No matter how you use \CONTEXT, you need to install it first. You can for
+    instance use \TEX live or another distribution to pick up \CONTEXT, but you
+    can also install it using the archive (snapshot), in which case you also need
+    to pick up the engine (for instance \LUATEX) and a basic set of fonts. In
+    order to make installation easy we provide a so called standalone
+    distribution that has all you need.
+\stopbuffer
+
+\startbuffer[4]
+
+    The standalone \CONTEXT\ distribution has the following characteristics:
+
+    \startitemize
+        \startitem
+            The installation is self contained. Apart from resources like fonts,
+            the \TEX\ macros, \LUA\ code and \METAPOST\ helpers are provided in
+            one package.
+        \stopitem
+        \startitem
+            There is only one binary involved: \LUAMETATEX. The source code of
+            this program is integral part of the \CONTEXT\ distribution (per end
+            2019). A user should be able to compile the program if needed. There
+            is no dependency on additional libraries other than those that make
+            up the operating system.
+        \stopitem
+        \startitem
+            The core system is able to typeset documents in an efficient way. The
+            memory footprint is decent and performance acceptable, also on on low
+            power devices and virtual machines. We try not to provide bloatware.
+        \stopitem
+        \startitem
+            The official user interface is stable and the implementation of core
+            components will not change fundamentally. When something can be
+            improved it will be. One can use a snapshot for long term stability.
+        \stopitem
+        \startitem
+            Support is provided by means of a mailing list, a wiki,
+            documentation, meetings, etc. If needed you can consult (or hire)
+            support. There are enough experienced users out there to get you
+            going.

+\startbuffer[5]
+    The first version of \CONTEXT, now tagged \MKII, has been around since 1995
+    and (still) runs on top of \PDFTEX. The development of its successor \MKIV\
+    started in 2005 as part of the \LUATEX\ development and still carries on. The
+    most recent incarnation is \LMTX, which is \MKIV\ but tuned for \LUAMETATEX,
+    the lean and mean successor of \LUATEX.

+\startbuffer[1]
+    The \LUAMETATEX\ engine is a follow up on \LUATEX. It integrates the \TEX\
+    text rendering engine, the \METAPOST\ graphic engine and the \LUA\ script
+    interpreter. The development is part of the \CONTEXT\ macro package
+    development. This macro package tightly integrates the three subsystems. The
+    \LUAMETATEX\ code is part of the \CONTEXT\ distribution.
+\stopbuffer
+
+\startbuffer[2]
+    The \LUAMETATEX\ engine is lean and mean. There is for instance no backend
+    code present. In \CONTEXT\ this is handled in \LUA. Graphic inclusion is also
+    delegated to \LUA. The \TEX\ frontend is a slightly extended version of the
+    \LUATEX\ one. System depedencies are minimized. Where possible we stay close
+    to the original \TEX\ concept because that is a well documented reference.
+    The binary can also be used as stand alone \LUA\ engine.
+\stopbuffer
+
+\startbuffer[3]
+    The \METAPOST\ library also has access to \LUA, which means that the language
+    can be enhanced and functionality added on demand. There are several graphic
+    libraries provided in \CONTEXT. This graphical language is efficient in
+    runtime and graphical output. In combination with \LUA\ we have a high
+    performance graphical subsystem that can handle a huge amount of data.
+    Additional text (like labels) is typeset at high quality.
+\stopbuffer
+
+\startbuffer[4]
+    The \LUA\ code that comes with \CONTEXT\ contains a lot of helper code which
+    means that one can set up selfcontained workflows without many extra
+    dependencies. Documents can be encoded in \TEX, \LUA, \XML\ or whatever
+    suits. There is support for databases too.
+\stopbuffer
+
+\startbuffer[5]
+    The \CONTEXT\ code base evolved over time. The basic functionality is quite stable.
+    The move from \MKII\ to \MKIV\ to \LMTX\ has been gradual. The efficiency in terms
+    of code and performance has been improved stepwise. Development continues and beta
+    releases occur on a regular basis. The \CONTEXT\ user community is quite willing
+    to experiment with betas that can be installed alongside stable snapshots.
+
+    \blank
+
+    The installation is relatively small (fonts make up much of it) and updating is
+    easy. We operate in the \TEX\ Directory Structure, which is a proven concept.

+
+    The \CONTEXT\ macro package is more than just a \TEX\ processor,
+    various input is possible, some we show here. An example of a
+    method not shown here is fetching data from a database. The
+    various input methods can be combined, so depending on what you
+    need you can mix \TEX\ (for typesetting text), \METAPOST\ (for
+    producing graphics) or \LUA\ (as language for manipulating
+    data.
+
+    All these methods are quite efficient and always have access to
+    the full power of the typesetting engine.
+
+    When you use \CONTEXT\ with \LUAMETATEX, you get a reasonable
+    small self contained component that can be used in workflows
+    that need quality rendering. The ecosystem is rather future
+    proof too.
+
+    The \CONTEXT\ macro package has been around for decades and
+    evolved from \MKII, to \MKIV\ and now \LMTX. The development
+    team has always been involved in the development of engines
+    like \PDFTEX, \LUATEX\ and \LUAMETATEX. There is an active
+    mailing list and there are \CONTEXT\ meetings.
