Step 4: Confirming the Installation
If Zope 3 is running, you should stop it at this point. Then you should start Zope 3 and read the messages it prints during startup. If it starts without any error messages, your package has been installed successfully.
Note that unlike Zope 2, Zope 3 has no way to show you which products have been successfully installed because there is no formal concept of a Zope 3 add-on. However, you can usually tell immediately whether an installation was successful by entering the ZMI. If the Wiki object is available as a new content type, you know the configuration was loaded correctly.
