 It is a reimplementation of [superboum's Bottin](https://github.com/superboum/bottin)
 using the Go programming language.
 
+**Use case:** [Deuxfleurs](https://deuxfleurs.fr) is a self-hosting collective
+where we try to build a resilient infrastructure with commodity hardware by
+having redundancy and auto-reconfiguration (this is why we use the Nomad+Consul
+stack).  We try to use replicated/high availability data stores everywhere we
+can, and Bottin helps us do this for the LDAP service.  We are not managing a
+high number of users at the moment and scalability is not our highest priority.

 Features:
 
 - most LDAP operations implemented (add, modify, delete, compare, search with most basic filters)
