 =head3 Requirements
 
-Building and installing this program only requires Perl modules from the
-standard library. So as long as you have Perl installed (which should be the
-case by default on almost all system), you should be able to install ptp using
-one of the method below. This program requires Perl version 5.22 or above. You
-can check which Perl you have installed with the following command:
+To install this program you need Perl and its cpanminus package manager. The
+B<perldoc> program is recommended but not required. You can these dependencies
+with one of the following command lines, depending on your OS:
 
-    perl -v
+    # On Debian, Ubuntu, Mint, etc.
+    sudo apt-get install perl cpanminus perl-doc build-essential
+
+    # On Red Hat, Fedora, CentOS, etc.
+    sudo yum install perl Perl-App-cpanminus perl-doc gcc make
+
+=head3 Installing from CPAN (recommanded)
+
+This program is available on CPAN (the Perl package manager). So, to install
+B<ptp> automatically using CPAN, you can just run the following command:
+
+    sudo cpanm App::PTP -n -L /usr/local --man-pages --install-args 'DESTINSTALLBIN=/usr/local/bin'
 
 =head3 Installing from the Git sources
 
-To install the program manually from Git, you can run the following commands
-(you do need to have the B<make> and B<git> program installed):
+To install the program manually from Git, you can run the following commands:
 
     git clone https://github.com/mkende/ptp.git
     cd ptp
+    cpanm --installdeps . -n --with-configure
     perl Makefile.PL
     make
-    make test
+    # Optionally:
+    # make test
     sudo make install
 
-=head3 Installing from CPAN
-
-This module is available on CPAN (the Perl package manager). The CPAN command
-should be installed on any system that has Perl (which, again, should mostly be
-any system at all). So, to install B<ptp> automatically using CPAN, you can just
-run the following command:
-
-    cpan App::PTP
-
-Note: if this is the first time that you run the B<cpan> command, you will be
-asked to configure it. The default answer to most questions is usually fine.
+Note that this approach is discouraged because you will need to reinstall B<ptp>
+every time you update your system Perl.
