 ### Dependencies
 
-The required Ubuntu packages are listed in the [documentation](./docs). Other ROS catkin packages such as [`rplidar_ros`](https://github.com/Slamtec/rplidar_ros) need to be cloned into the catkin workspace. It is planned to use [`vcstool`](https://github.com/dirk-thomas/vcstool) in the future to automate the dependency installtions.

 ### Tooling
 
-- [`vcstool`](https://github.com/dirk-thomas/vcstool) to simplify external dependency installation
-- Adding instructions how to use [`rosdep`](http://wiki.ros.org/rosdep) to install required system dependencies
 - Use [clang format](https://clang.llvm.org/docs/ClangFormat.html) together with [`.clang-format`](https://github.com/PickNikRobotics/roscpp_code_format) file for `roscpp` to comply with [ROS C++ Style Guidelines](http://wiki.ros.org/CppStyleGuide)
