+Binary install (via ROS)
+------------------------------
+
+(November 2015) Now you can install binary on Ubuntu (via ROS). As of today limited to Ubuntu Saucy and Trusty. To do so:
+
+ 1. Add ROS repository to your Ubuntu's download site (For detail, see [ROS wiki](http://wiki.ros.org/indigo/Installation/Ubuntu)):
+
+ ```
+sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
+sudo apt-key adv --keyserver hkp://pool.sks-keyservers.net --recv-key 0xB01FA116
+sudo apt-get update
+```
+
+ 2. Install CSM. 
+
+ ```
+sudo apt-get install ros-indigo-csm
+```
+
+The package name contains "ROS" specific info, but you can use this as a standalone CSM library. It goes into these directory:
+
+ ```
+/opt/ros/indigo/include/csm
+/opt/ros/indigo/lib/libcsm-static.a
+/opt/ros/indigo/lib/libcsm.so
+```
