+A **DU**niter **I**mprovement **P**roposal (**DIP**) is a design document describing new feature for Duniter or its processes or environment. The DUIP should provide a concise technical specification of the feature and a ratonale for the feature.
+
+We intend DUIPs to be the primary mechanics for proposing new features, for collecing community input on an issue, and for documenting the design decisions the have gone into Duniter. The DUIP author is responsible for building consensus within the community and documenting dissenting opinions.
+
+Because the DUIPs are maintained as text files in a versioned repository, their revision history is the historical record of the feature proposal.
