I want to be an OpenOffice.org developer
From Apache OpenOffice Wiki
Welcome to OpenOffice.org! :-)
You are at the start of a long, but very exciting way! There are more ways how to start, but the easiest one is to:
- build your own OpenOffice.org so that you are able to modify things
- pick up your favorite bug/annoyance, and & try to fix that
Description how to do it is here: Getting started with OOo development
If you don't find the instructions in the Wiki good enough to guide you, feel free to ask on the dev@openoffice.org mailing list. If you are interested in some aspect that is not covered, ask the mailing list as well :-) - we'll guide you where to find people who will be able to answer your questions.
We are looking forward to your contribution!
