 This file briefly describes how to install SZARP software. The simplest way of
 installation for end-users it to use Debian packages.
 
-SZARP is compile and run on Debian GNU/Linux (i386, amd64, armel/armhf)
-and Ubuntu. Some client applications are also cross-compiled for Windows.
-All the development and testing is done only on Debian GNU/Linux, so you can
-run into some problems with other distributions.
-
-See INSTALL.Windows for information about Windows platform.

 Then you can replace binaries with your own compiled versions or run them

-SZARP uses autotools, but is deployed without configure scripts, so you need
-automake, autoconf, libtool and pkg-config. The commands to build SZARP are:
-
-# ./autogen.sh
-
-This invokes automake and autoconf, it should run without any error messages.
-In case of errors, check whether you have newest versions of automake,
-autoconf, libtool and pkg-config installed.
-
-# ./configure
-
-This is the invocation of configure scripts. There are many options available,
-see:
-
-# ./configure --help
-
-Configuration for Windows is described in INSTALL.Windows. There are 
-'--with-XXX' and '--without-XXX' options available to turn on/off optional 
-libraries. For example, to get server-only software (and get short compile time),
-you can use '--without-x'.
-
-By default all optional libraries are turned on. If some library is not found,
-SZARP is configured without this library. At the end of configure run, there's
-a report generated with information what libraries where found. To get full
-functionality, you must have all libraries. You can skip some libraries, but
-some parts of code will fail to compile (yes, we don't test every possible 
-combination of missing libraries). The safest bet is to have all libraries.
+SZARP uses cmake for build and deployment (some files may still be deployed with
+with configure scripts), so you need cmake to start with.
+The commands to build SZARP are:
 
-If you plan to debug programs, you should change compiler options. By default
-'-g' is used, but -O2 (optimization) fools debugger. To get debugger-friendly
-code run configure with options:
+# cmake .
 
-# ./configure CFLAGS=-g CXXFLAGS=-g
-
-Now:
+This invokes cmake and runs checks for missing libraries. All libraries
+should be present for SZARP to build and run properly.
 
 # make
 
-This should compile everything. If there are errors, you have found a bug. But
-if you're not using some old releases of Debian (ie. lenny, squeeze), there's
-a little chance that we will help you with this. Patches are welcome if they do
-not brake Debian compilation ;-). If you configure SZARP with LUA parameters
-optimiser enabled, you need a lot of memory during compilation - about 1 GB
-without '-g' options, 2 GB is better if you use '-g'.
-
-# make doc
-
-This creates html documentation. You need lots of Docbook stuff installed for
-this to work, ./configure should warn you about missing programs.
+This should compile everything, including documentation. If there are errors,
+you have found a bug. Patches are welcome if they don't break Debian builds.
+For building SZARP you will need at least 4GB RAM, as parts of the code use
+templates extensively, more is recommended.
 
 Now you can become root and type:
 
 # make install
 
-Default install directory is /opt/szarp. You can install SZARP under other
-directory by using:
-
-# make DESTDIR=/tmp install
-
-or by passing '--prefix' argument to ./configure.
-
-To install programs without debugger information (smaller, faster binaries
-but debugging not possible), you can use:
-
-# make install-strip
+Default install directory is /opt/szarp.
