 SMACC2 is an event-driven, asynchronous, behavioral state machine library for real-time ROS 2 (Robotic Operating System) applications written in C++, designed to allow programmers to build robot control applications for multicomponent robots, in an intuitive and systematic manner.
 
-SMACC was inspired by Harel's statecharts and the [SMACH ROS package](http://wiki.ros.org/smach). SMACC is built on top of the [Boost StateChart library](https://www.boost.org/doc/libs/1_53_0/libs/statechart/doc/index.html).

 Operating instructions can be found in each reference state machines readme file.
 
-## Writing your State Machines
-There is a [state machine generator in the reference library](smacc2_sm_reference_library/create-sm-package.bash).
-To use it go to the `src` folder of your ROS 2 workspace and execute:
-  ```
-  smacc2/smacc2_sm_reference_library/create-sm-package.bash <name_of_state_machine>
-  ```
-After than compile your workspace and source it to set paths of the new package.
-Check `README.md` in new package about instructions to start newly created state machine.

 Happy Coding!
