Low-Energy Kaon Interactions and Scattering on Nucleons and Light Nuclei
  A chapter to be included in "The DA$\mit\Phi$NE Physics Handbook" by the DA$\Phi$NE Theory Working Group, this paper covers the phenomenology of low--energy $K N$ physics, with particular emphasis on the problems still to be solved by a careful experimental investigation and on the theoretical tools to analyse it.
