 Installing fdupes
 --------------------------------------------------------------------
-To install the program, issue the following commands:
-
-make fdupes
-su root
-make install
-
-This will install the program in /usr/local/bin. You may change this 
-to a different location by editing the Makefile. Please refer to
-the Makefile for an explanation of compile-time options. If you're
-having trouble compiling, please take a look at the Makefile.
-
-UPGRADING NOTE: When upgrading from a version prior to 1.2, it should 
-be noted that the default installation directory for the fdupes man
-page has changed from "/usr/man" to "/usr/local/man". If installing
-to the default location you should delete the old man page before
-proceeding. This file would be named "/usr/man/man1/fdupes.1".
-
-A test directory is included so that you may familiarise yourself
-with the way fdupes operates. You may test the program before
-installing it by issuing a command such as "./fdupes testdir" 
-or "./fdupes -r testdir", just to name a couple of examples. Refer
-to the documentation for information on valid options.
+You're looking at a DEVELOPMENT version of fdupes. If you're not a software
+developer or you just want to install the program, this is probably not the
+version you want. This version of fdupes is currently in development and
+subject to change. The features and functionality present in this version
+may not reflect the features and functionality in the final release.
+
+The easiest way to install fdupes is to use your operating system's package
+manager, if available. If that's not an option or you'd prefer to compile
+the program yourself (which may sometimes be the only way to obtain the
+latest version), you should download a RELEASE version of fdupes and follow
+the installation instructions provided with it.
+
+As of this writing, fdupes releases may be downloaded from:
+
+	https://github.com/adrianlopezroche/fdupes/releases
+
+If you're a programmer and you wish to use or work on this version of fdupes
+you will need to install autoconf and automake on your system and run
+
+	autoreconf --install
+
+to generate the configure script and other files needed for compilation and
+installation. After that you may compile fdupes by running:
+
+	./configure
+	make
+
+and install it by running:
+
+	sudo make install

+Installing fdupes
+--------------------------------------------------------------------
+To build and install the program, issue the following commands:
+
+	./configure
+	make
+	sudo make install
+
+Starting with fdupes 2.0.0, a full-featured installation requires
+the following libraries to be installed on your system:
+
+  - ncursesw (ncurses with support for wide characters)
+  - PCRE2 (Perl Compatible Regular Expressions library)
+
+Source code for these libraries is available at:
+
+  https://www.gnu.org/software/ncurses/
+  https://www.pcre.org/
+
+If these libraries are not available on your system or you want to
+build fdupes without them, you may instead call configure as:
+
+	./configure --without-ncurses
+
+followed by "make" and "sudo make install" as before.
+
+Please note that compiling fdupes without these libraries will
+disable the new screen-mode interface for choosing which files to
+keep or delete. Without them, fdupes will use an interface like
+the one used in previous versions.
+
+The commands above will build and install fdupes and its
+documentation under /usr/local by default. You may change the
+install location using:
+
+	./configure --prefix=/your/chosen/path
+
+followed by "make" and "sudo make install" as before.
+
+A test directory is included so that you may familiarise yourself
+with the way fdupes operates. You may test the program before
+installing it by issuing a command such as "./fdupes testdir" 
+or "./fdupes -r testdir", just to name a couple of examples. Refer
+to the documentation for information on valid options.
