-MSCL pre-built packages can be found here: [MSCL Packages](https://github.com/LORD-MicroStrain/MSCL/releases/tag/v62.0.0)
+MSCL is now installed in the [CMakeLists.txt](./ros_mscl/CMakeLists.txt). The version installed can be changed by passing the flag `-DMSCL_VERSION="62.0.0"`
 
 We do our best to keep ROS-MSCL up-to-date with the latest MSCL changes, but sometimes there is a delay. The currently supported version of MSCL is [v62.0.0](https://github.com/LORD-MicroStrain/MSCL/releases/tag/v62.0.0)

-If you choose to install MSCL at a location other than /usr/share, [CMakeLists.txt](https://github.com/LORD-MicroStrain/ROS-MSCL/blob/master/ros_mscl/CMakeLists.txt) will need to be updated with the install path.
