 This package allows to convert TypeScript language State Machine developed
 using [Xstate](https://github.com/davidkpiano/xstate) into C++ generated SM, no coding required.
 
-Project location: https://github.com/shuvalov-mdb/xstate-cpp-generator
-Copyright Andrew Shuvalov, MIT [License](https://github.com/shuvalov-mdb/xstate-cpp-generator/blob/master/LICENSE)
+* Project location: https://github.com/shuvalov-mdb/xstate-cpp-generator
+* NPM TypeScript package location: https://www.npmjs.com/package/xstate-cpp-generator
+* Copyright Andrew Shuvalov, MIT [License](https://github.com/shuvalov-mdb/xstate-cpp-generator/blob/master/LICENSE)
 
 ## Features
 
 * Design and test the State Machine in [Xstate](https://github.com/davidkpiano/xstate) and then convert to C++ without any changes
   * Use the [online vizualizer](https://xstate.js.org/viz/) to debug the State Machine
-* SM basics: [States](https://xstate.js.org/docs/guides/states.html), [Events](https://xstate.js.org/docs/guides/events.html), [Transitions](https://xstate.js.org/docs/guides/transitions.html)
+* SM basic features supported: [States](https://xstate.js.org/docs/guides/states.html), [Events](https://xstate.js.org/docs/guides/events.html), [Transitions](https://xstate.js.org/docs/guides/transitions.html)
+  * SM extra features supported: [Actions](https://xstate.js.org/docs/guides/actions.html#declarative-actions)
 * Generated C++ is fully synchronized, safe to use in multi-threaded environemnt without any changes
-* No exteral dependencies except STL. No boost dependency.
-* Callback model based on subclassing and virtual methods
-  * Callbacks are invoked when: leaving a state, entering a state, after entering a state
+* No external dependencies except STL. No boost dependency.
+* Callback model:
+  * Entry, Exit and Trasition [Actions](https://xstate.js.org/docs/guides/actions.html#declarative-actions) are code
+   generated as static methods in the template object used to declare the State Machine and can be implemented by the user
+  * Every state and transtion callbacks are generated as virtual methods that can be overloaded by subclassing
 * Arbitrary user-defined data structure (called Context) can be stored in the SM
 * Any event can have an arbitrary user-defined payload attached. The event payload is propagated to related callbacks

 You should see new generated files:
