# FAQ - Frequently Asked Questions

There are UML Icons missing in my toolbar, where are they?

You probably not installed Umbrello correctly, and it cannot find the icons.

If you installed Umbrello from a pre-compiled binary package, please contact the packager and inform him about this so that he can fix the package. If you installed from source you probably did not pass the correct ``--prefix`` argument to `configure`. Please read the installation chapter of this documentation.

I have another question not answered by this documentation, where can I find further information?

If you have a question about usage of Umbrello or about UML in general, you can subscribe and write a mail to the Umbrello's user list at uml-user@lists.sourceforge.net

If you have a question about Umbrello's development, you can contact the developers directly by subscribing and sending a mail to the Umbrello's developers list at uml-devel@lists.sourceforge.net

Further information and contact addresses, as well as archives of the mailing lists can be found on Umbrello's home page at http://uml.sf.net.
