From 35C3 Wiki
To create a new page for an Assembly, read the Assemblies information page and then just enter the name of the Assembly below. This will show you a form requesting some basic information about the Assembly like a short description. This year we have some changes so please check all fields and their descriptions!
You can also insert the name of an existing Assembly to edit it, but it might be easier to head over the Assemblies page and click "Edit with form".
For more information, see Assemblies.
