-# Working Groups
-
-HSF Working Groups are community led groups that organise activities
-in particular domains with the aims of increasing communication
-between developers, providing a platform for discussion of interesting
-problems and novel solutions developments, and fostering the adoption
-of common software between different communities.
-
-Working groups have three conveners, to help share the workload, and
-are appointed by the HSF (via an open nomination process and a search
-committee) to serve for one year, with renewal possible by mutual
-agreement. (In contrast, [interest groups and activity areas]({{ site.baseurl }}/what_are_activities.html)
-are less formal.)
-
-We strive for a diverse representation in the HSF working groups and, in
-particular, we very strongly favour having conveners from three different
-experiments.
-
-If you want to form a working group, or want to put some community-wide
-activity under the umbrella of the HSF,
-just contact the
-[HSF Steering Group](mailto:hsf-steering@googlegroups.com).
-
-Working Groups are added to the website of the HSF, with
-description and contact information, and their own
-[Indico category](https://indico.cern.ch/category/7972/).

-## Being an HSF Working Group Convener
-
-The HSF is extremely grateful to members of the community who take on the role
-of convener in the working groups - *thank you*. Each working group engages
-with a different subset of the developer and physics community and thus the
-exact pattern of activities that are organised can vary. It is delegated to the
-conveners to decide the way to organise so that it best serves the needs in
-HEP software and computing as required. That said, organising an event every
-4 to 6 weeks is usually a good cadence, although sometimes a series of related
-events might happen bunched together more tightly, e.g., looking at one
-specific topic from the point of view of several experiments.
-
-HSF Working Group meetings in general should try to:
-
-- be there to help encourage the exchange of ideas and techniques
-- do not need to focus on "finished" items, but rather can be there
- to provide a community forum for unsolved problems
-- should ensure there is plenty of time for discussion
-- should take notes or minutes for important discussion points (attaching these
- to Indico is recommended)
-
-We strongly encourage the use of common software in the HSF and opportunities
-for common development and sharing should be seized when they exist. The HSF
-exists as a [GitHub organisation](https://github.com/HSF) and is happy
-to host projects to help them grow. This can include things like common
-datasets used in development as well as actual code.
-
-One focus that we encourage is to organise events together with other
-groups, e.g., a special session at a workshop, a joint meeting with
-a software development project, a cross-cutting topic that bridges
-more than one HSF working group (our working groups are not intended to
-be silos). These meetings are excellent for bringing together
-people that might not normally talk or know each other.
-
-Our working group conveners should usually dedicate between 5% and 10% of their
-time to running the working group. More than 10% is great, but we recognise
-that people are busy with many other tasks. Less than 5% and the working group
-can fall into an inactive state. Conveners should meet at least once a month to
-plan. The HSF Steering Group is always happy to attend to give feedback
-and suggestions.
-
-At least one of the working group conveners should attend the bi-weekly
-[HSF Coordination Meetings](https://indico.cern.ch/category/7970/) and
-give a short update on the group's recent and forthcoming activities.
-
-When the HSF organises [workshops](https://indico.cern.ch/category/7971/)
-working group conveners can give input to the organising team. If there
-will be a session dedicated to the activities of any working group then
-conveners will be asked to co-organise it.
-
-### Recording Meetings and Minutes
-
-In general, recording *is appropriate* for HSF meetings, which are there to
-foster discussion and collaboration, so *we do recommend it*. There are a lot of
-meetings and we have a worldwide community, so not everyone who is interested
-can join a meeting and recordings can help people to catch-up.
-
-However, you need to make it very clear with the speakers and to participants that:
-
-- The meeting is being recorded and will be made public;
-- And where the video will be posted ([YouTube]({{ site.baseurl }}/organization/youtube.html), [CDS](http://cds.cern.ch/record/2289430), etc.);
- - Note that it is strongly recommended not to add video files directly into Indico, instead post a link to CDS.
-
-In any case, *please also make sure that meetings are minuted in a concise way*
-(it’s not always the case that people have the time to watch the 60 minute
-video and they need a shorter summary). Minutes can be posted directly onto
-Indico (easy) or to the [HSF website]({{ site.baseurl }}/howto-website.html) (via a PR).
