+Adding new OS platforms OR build pre-requisites
+===============================================
+Since all of the Dockerfiles libvirt uses for CI have been generated by ``lcitool``
+provided by the `libvirt-ci <https://gitlab.com/libvirt/libvirt-ci.git>`__
project,
+most relevant changes will need to be introduced to ``lcitool`` first.
+In cases where ``libvirt-ci`` does not know about the OS distro/build
+pre-requisite that is desired to be tested, proceed with the following:
+ * Send a mail regarding your desired build/coverage change to libvir-list
+ Note that in case you're looking into adding a new OS platform there are
+ limited CI compute resources available to libvirt, so the cost/benefit
+ trade-off of adding new OS distros needs to be considered and
+ is subject to a discussion on the mailing list.
+ * File an issue at https://gitlab.com/libvirt/libvirt-ci/-/issues
+ pointing to the libvir-list mail thread in the archives.
+ This alerts other people who might be interested in the work
+ to avoid duplication, as well as to get feedback from libvirt-ci
+ maintainers on any tips to ease the addition.
+Assuming there is agreement to the change you wish to make then
+ #. Fork the ``libvirt-ci`` project on gitlab
+ #.
+ * If adding a new OS distro, add metadata under
+ ``guests/lcitool/lcitool/ansible/group_vars/``
+ for the new OS distro. There might be code changes required if
+ the OS distro uses a package format not currently known. The
+ ``libvirt-ci`` maintainers can advise on this when the issue
+ is file. Edit the ``mappings.yml`` file to update all the existing package
+ entries, providing details of the new OS distro **OR**
+ * If **NOT** adding a new OS distro, simply edit the ``mappings.yml`` file
+ to provide a distro-agnostic mapping for the pre-requisite you're adding
+ #. Commit the ``mappings.yml`` change and submit a merge request to
+ the ``libvirt-ci`` project
+ #. CI pipeline will run to validate that the changes to ``mappings.yml``
+ are correct, by attempting to install the newly listed package on
+ all OS distributions supported by ``libvirt-ci``
+ #. Once the merge request is accepted, go back to libvirt and update the
+ ``ci/manifest.yml`` file to reflect your change
+ #. From the root of the libvirt git repository run
+::
+ $ lcitool manifest
