Add installation by Docker

README.md

@@ -44,6 +44,20 @@ If running `openface2_ros` results in a segfault or you see the following lines
 
 then openface2 ros is linking against OpenCV2 instead of OpenCV3. To fix this: update cmake to at least 3.6.2, rebuild OpenCV3, clone vision\_opencv into the src folder of your catkin workspace, then recompile cv\_bridge. Remake your catkin workspace, and the segfault and warnings should have been resolved.
