User base is open for everyone to read. KOrganizer's user base wiki documentation needs to be updated with the latest screenshots in the screen shot section. You need to create an OpenID account or have a KDE Identity Login with you to begin.

• Use Kubuntu Linux distro for your work, preferably Kubuntu/Plasma5 live CD if you don't want to install an entire system with plasma5.
• Install KOrganizer in your system.
• Update the relevant screenshots.
• Ping me when you are done with the task! ( nikam on #kde-soc )

Good Luck!
