  Low luminosity dwarf galaxies provide stringent constraints on the nature of
dark matter. Establishing these constraints depends on precise kinematic
measurements of individual stars. In this overview for non-specialists, we
describe current and future prospects for three unique tests of dark matter
using resolved stellar kinematics in low luminosity galaxies: the overall
number of satellite galaxies around the Milky Way, dark-matter annihilation
radiation from dwarf galaxies, and their internal density profiles. We then
assess the prospects for meaningfully testing theories of dark matter based on
the improved kinematic precision expected from upcoming facilities.
