This documentation is for the new OMERO 5.3 version. See the latest OMERO 5.2.x version or the previous versions page to find documentation for the OMERO version you are using if you have not upgraded yet.
The OMERO server system provides storage and processing of image data which conforms to the OME Specification. It can be run on commodity hardware to provide your own storage needs, or run site-wide to provide a large-scale collaborative environment.
Although getting started with the server is relatively straightforward, it does require installing several software systems, and more advanced usage including backups and integrated logins, needs a knowledgeable system administrator.
You may find the OMERO clients overview user guide useful before working through the installation and maintenance guides provided in this section of the documentation.
The server system is composed of several components, each of which runs in a separate process but is co-ordinated centrally.
If you are interested in building components for the server, modifying an existing component, or just looking for more background information, there is a section about the server within the Developer Documentation; the best starting point is the OMERO.server overview for developers.
