+### Why should I donate?
+
+To make a concrete contribution to the maintenance and development of Haskell community infrastructure, including the hosting and deployment of community resources, from Hackage to Hoogle and beyond, the best thing to do is find a way to volunteer and get involved! However, donations are also very welcome and needed. We will find ways to put donations to good use, be they for infrastructure administration, new hardware, or continued work on software infrastructure projects.
