 Installation
 ============
 
-We assume that the system is a minimal installation of Ubuntu 20.04 LTS.
-Ideally, you should have two hosts, ``exchange-online`` and
-``exchange-offline``.  It is also possible to run the HTTPS nginx server or
-the PostgreSQL database on yet another host, but in these instructions we will
-assume that only two hosts are used. Alas, the instructions will also work if
-you run everything on one system, but then you have the security drawback of
-not keeping the high-security private keys disconnected from the Internet.
-
-To install the exchange, first make sure that your system is up-to-date
-and that the ``gnupg`` package has been installed.
-
-.. code-block:: shell-session
-
-  [root@exchange-online]# apt-get update
-  [root@exchange-online]# apt-get upgrade
-
-Next, add the ``focal-fossa`` apt repository provided by Taler Systems S.A. to
-your package sources:
-
-.. code-block:: shell-session
+Please see the chapter on `exchange installation <ExchangeInstallation>`_ for
+various ways to install a GNU Taler exchange.
 
-  [root@exchange-online]# cat > /etc/apt/sources.list.d/taler.list <<EOF
-  deb https://deb.taler.net/apt/ubuntu focal-fossa main
-  EOF
-  [root@exchange-online]# dpkg --remove-architecture i386
-
-The second command is optional.  It tells ``apt-get update`` to not
-bother with the ``i386`` architecture (thus avoiding a warning, later).
-If you use this, make sure you do not use any 32-bit applications.
-
-Before installing Taler packages, you need to add the Taler Systems S.A. 
package

+Note that it is possible to run the HTTPS reverse proxy or

+you will thus need to install an HTTPS reverse proxy and the database:
 
 .. code-block:: shell-session
 
-  [root@exchange-online]# wget -O - https://taler.net/taler-systems.gpg.key | 
apt-key add -
   [root@exchange-online]# apt-get update
-
-Finally, the required packages can be installed:
-
-.. code-block:: shell-session
-
   [root@exchange-online]# apt-get install -y nginx postgresql
-  [root@exchange-online]# apt-get install -y taler-exchange 
taler-exchange-offline
-  [root@exchange-online]# apt-get install -y taler-merchant taler-wallet-cli
-
-By default, all installed services will be disabled.  You need to enable
-and start them later.
-
-While ``taler-merchant`` and ``taler-wallet-cli`` are not required to operate 
an
-exchange, they are useful for testing.  When asked about using dbconfig to 
configure
-the merchant's database, select ``yes``.
