Welcome to the online documentation of eZ components.
The documentation for 1.1.1 now offers a better way of documenting properties of a class. Instead of this documentation being in the general class description there is now a table just like the class' variables. The second improvement is the marking of "main classes" in the class trees. The main classes are the classes that you should have a look at when using a component and are essential for the use of a component. They are marked for most of the components with bold text now.
The API reference for each component is available through the component links on the left side.
eZ components can be installed using a tar.gz/zip bundle or through the PEAR installer. The article An introduction to eZ components explains both installation methods.
