 2. A **web server** to host DIBS.  The current version of DIBS has only been tested with Apache2 on Linux (specifically, Ubuntu 20) and macOS (specifically 10.13, High Sierra). DIBS comes with a WSGI adapter file and sample config file for Apache, but it should be possible to run DIBS in other WSGI-compliant servers.
 3. An **authentication layer**. For authentication, DIBS assumes that the web server takes care of user authentication in such a way that DIBS is behind the authentication layer and all users who can reach the DIBS pages are allowed to view content. DIBS only implements checks to distinguish between regular users versus staff who are allowed to access restricted pages. For the authentication layer, at Caltech we use the [Shibboleth](https://en.wikipedia.org/wiki/Shibboleth_Single_Sign-on_architecture) single sign-on system, but it is possible to use other schemes.  The installation and configuration of a single sign-on system depends on the specifics of a given institution, and are not described here.
 4. Modification to the metadata retrieval code. We strove to limit dependencies on external systems, but the interface for staff to add items to DIBS requires looking up some limited metadata based on an item's barcode, and lacking a universal scheme or ILS interface to do that, we had to hard code the access. Thankfully, this is limited to just a few lines in  [`server.py`](dibs/server.py). We currently use TIND at Caltech, so unless you also use TIND, you will need to modify the TIND-specific lines in that file.
-5. Modification to the HTML templates to change the branding. The template files in [dibs/templates](dibs/templates) are specific to Caltech, and will need to be edited to suit another installation. (We are open to making the branding customization easier and would welcome a [pull request](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests) for suitable changes!)
