-        <description>Any bit of time you can spare on Friday will be helpful! Ideally you can be there from 12:00 until
-            ready. Experience learns us we'll be ready between 18:30 and 22:00 (hard deadline, have to leave the
-            building). Just come in as early you can! We'll have some pizza or other food in the evening. Deadline is
-            22:00. Some of us go to the beer event afterwards.

+Buildup is a great task for first-time volunteers, as you will get to know the conference, the volunteers and the staff very well. As a task, it is fairly simple: each year we have to convert five university buildings to a location fit for FOSDEM.
+
+There are many jobs to do: setting up stands, covering the wall with the famous brown paper, running cables, putting up signs, etc. While carrying heavy stuff around is sometimes required, other work requires a more delicate touch.
+
+We usually start at 12:00 and hope to finish before 19:00 (we have to leave the building at 22:00, so that's our deadline). Around that time, someone will bring food for everyone, usually Chinese.
 
-            This task includes many subtasks. Some require carrying heavy stuff around, some don't. We need to set up
-            stands (tables, chairs), cover the walls in brown paper, put signalization in place, run power cords, ...
-            There will be 3 work areas, each with their own coordinator.
+As you can imagine, this is a mammoth task, and more volunteers are always wanted. So if you can't make it at 12:00, come a little later. There will be enough work to do to keep you busy, don't worry!
