From the OMERO product site:
"From the microscope to publication, OMERO handles all your images in a secure central repository. You can view, organize, analyze and share your data from anywhere you have internet access. Work with your images from a desktop app (Windows, Mac or Linux), from the web or from 3rd party software."
These pages focus on providing instructions for installing the OMERO server and integrate the server with LDAP (active directory) for authentication and group membership.
Scripts and utilities can be downloaded from the download page. These can be used as building blocks for unattended installations.
