Installation/Upgrade and Configuration of phpGroupWare has been made as easy as possible. Most of the work is point and click. By carefully reading this document you can easly install phpGroupWare. Since this is still a beta version we do expect some bugs. You will need PHP compiled and installed on your system. You will also need MySQL, PostgreSQL or Oracle setup. If you are planning on using the email system, you will need to have an IMAP server installed and IMAP support compiled into PHP, or a POP3 server installed. You can have it installed as an Apache module or CGI mode for other web servers, the Apache module is preferred. We will assume that you are running on a Linux or other Unix system for these steps. Windows is supported, but there is no documentation for it currently.

While we are still in the Beta phase of phpGroupWare, you may want to track the CVS copy as closely as possible. The released versions are more stable, but often contain bugs that have been fixed in the CVS version. The downloads section on the site contains links to the most recent releases, and several mirror sites for the releases. If you have never used CVS, you may want to read through the doucmentation found at www.cvshome.org . The CVS pages for the core and apps projects can be found at phpGroupWare Core CVS , and phpGroupWare Apps CVS. Follow the directions for Anonymous CVS access and you should have the most recent development copy of phpGroupWare in no time. &installing; &troubleshoot;
