  KM3NeT is a future research infrastructure in the Mediterranean Sea, hosting
a multi-cubic-kilometre neutrino telescope and nodes for Earth and Sea
sciences. In this report we shortly summarise the genesis of the KM3NeT project
and present key elements of its technical design. The physics objectives of the
KM3NeT neutrino telescope and some selected sensitivity estimates are
discussed. Finally, some first results from prototype operations and the next
steps towards implementation - in particular the first construction phase in
2014/15 - are described.
