@@ -9,7 +9,7 @@ Kalibr is a toolbox that solves the following calibration problems:
 
 1. **Multi-Camera Calibration**: Intrinsic and extrinsic calibration of a camera-systems with non-globally shared overlapping fields of view with support for a wide range of [camera models](https://github.com/ethz-asl/kalibr/wiki/supported-models).
 1. **Visual-Inertial Calibration (CAM-IMU)**: Spatial and temporal calibration of an IMU w.r.t a camera-system along with IMU intrinsic parameters
-1. **Multi-Inertial Calibration (IMU-IMU)**: Spatial and temporal calibration of an IMU w.r.t a base visual-inertial sensing pair along with IMU intrinsic parameters.
+1. **Multi-Inertial Calibration (IMU-IMU)**: Spatial and temporal calibration of an IMU w.r.t a base inertial sensor along with IMU intrinsic parameters (requires 1-aiding camera sensor).
 1. **Rolling Shutter Camera Calibration**: Full intrinsic calibration (projection, distortion and shutter parameters) of rolling shutter cameras.
 
 To install follow the [install wiki page](https://github.com/ethz-asl/kalibr/wiki/installation) instructions for which you can either use Docker or install from source in a ROS workspace.
