 ## Description
 
-The iri_adc_landmarks_slam_solver project description
+This node provides a global localization based on landmarks. On the ADC competition, these landmarks are [ar_track_alvar](http://wiki.ros.org/ar_track_alvar) tags. This node takes the filtered ar tag detections of both cameras and optimizes a landmark based slam problem to get the robot position. It uses [Ceres Solver](http://ceres-solver.org/index.html) to make the optimization.
