* Add three milestones for HIFIS Software Technology to roadmap on
hifis.net.
  * Go-live for Helmholtz-wide GitLab.
  * Offer CI as a Service.

+## Helmholtz-wide GitLab on new Ansible-managed Infrastructure
+The [GitLab pilot service](https://gitlab.hzdr.de) will be put in a new 
+Ansible-managed infrastructure.
+[Ansible](https://www.ansible.com/) is a well-established configuration
+management tool.
+Maintenance and further developments of the Helmholtz-wide GitLab will be done
+with this tool.
+Other research centres are then able to use the so called
+[Ansible playbook](https://gitlab.hzdr.de/hifis-software-deployment/gitlab)
+to set up and run their own GitLab instance on dedicated servers in their own
+infrastructure with ease.
+Access to this Helmholtz-wide GitLab will be granted to all people affiliated
+with the Helmholtz Association and partners to increase cross-centre
+collaboration in research software projects.
+If users encounter any issues, they can report them in the respective
+[issue-tracker](https://gitlab.hzdr.de/fwcc/HZDR-GitLab).

+## CI as a Service as a Pilot Service
+Beside the [Helmholtz-wide GitLab](https://gitlab.hzdr.de) many Helmholtz
+centres run their own GitLab instances on dedicated infrastructure of their
+centre.
+This is also the case for GitLab's Continuous Integration (CI) runners,
+i.e. servers that are running CI pipelines, they are hosted by each centre
+separately.
+In order to bundle these resources and enable research software projects
+that are hosted on these GitLab instances to do Continuous Integration,
+CI will be offered as a service.
+CI runners that will be available for the Helmholtz-wide GitLab will then
+also be available to other GitLab instances of other centres.
+In order to start with these services a few pilot centres will be selected that
+will host these CI runners as a Service at the beginning.

+## Conceptualize Binder / ShinyR Integration into GitLab
+There are tools like [Binder](https://mybinder.org/)
+and [ShinyR](https://shiny.rstudio.com/)
+available that enable research software developers to publish their Jupyter
+notebooks or R scripts in interactive web-apps.
+This functionality will be integrated into the
+[Helmholtz-wide GitLab](https://gitlab.hzdr.de).
+First and foremost, a concept will be elaborated on how this integration
+could be realized.
