The post-installation configuration of Verkkoke 1.1 should be done using web based Graphical Configuration Interface. GCI main script file is web/configGUI/index.php which should be accessible if your web server is configured correctly. GCI has descriptions of different parameters and other help. Please remember that GCI must be run at least once and configuration saved to synchronize different configuration files in the system.
If you know, or wish to know, what you are doing, you can edit configuration file phpinc/config.php by hand. File is quite well documented, so it should be relatively easy to change some settings through there, if needed.
There is also a file phpinc/resources.php that contains resource links that are shown to students if their score is less than 100 %. Edit it, if you wish to add or remove resources.
