 == Prerequisites
 
-* you need 'docker'
-* If using Debian buster or higher, you must(!) add "vsyscall=emulate" option
-to the Linux kernel boot option, because CentOS 6.xx triggers syscalls in an
-outdated way.
+* Desktop environment
+* Perl
+* Perl module (download at https://metacpan.org/pod/Selenium::Remote::Driver)
+** install using "cpanm Selenium::Remote::Driver"
+* Chrome browser (downlaod at https://www.google.com/intl/de_de/chrome/)
+* Selenium browser driver driver for the Chrome version that is installed on the system (download at https://sites.google.com/a/chromium.org/chromedriver/, via https://www.seleniumhq.org/download/)
 
 == How to build
 
-# If something was built, delete all containers for specific image:
-docker ps -a | awk '{ print $1,$2 }' | grep checkit-tiff | awk '{print $1 }' | xargs -I {} docker rm {}
+* You don't have to do anything, just run the script.
 
-# build stuff
-docker build -t checkit-tiff --rm=true ./

+== How to run
 
+* general invocation
