We have documents both for new users and experienced users as well as for beta testers and developers. There are also Translations of the KMeleonWiki pages if you prefer another language than English.
In the Tutorials section you will find a set of friendly texts that walk you through some common tasks, such as how to disable popup windows, how to install a new skin or how to install Sun's Java plugin.
