This is the 6th edition of the Real Time Control Workshop series that follows the the previos ones. The real-time control (RTC) system is a crucial component for any astronomical adaptive optics (AO) system. The computational, and  data transfer demands placed on the next generation RTCs for future extremely large telescopes (ELTs) are enormous, and even current systems require skill to implement. The main workshop goal is to gather international AO RTC specialists in order to share and exchange experience regarding the design and implementation of these systems. Such shared experience can be used to improve the design of new and proposed AO systems, increasing their performance and usability. As such, the workshop is aimed at real-time control specialists, instrument scientists and adaptive optics engineers.  Although the workshop is focused principally on astronomical AO, attendence of participants from non-astronomical areas is welcome and indeed encouraged to allow cross-discipline discussions to take place.
