  1. I want to run this project locally and see the codebase. Please tell me how to open it in the browser tab when running the npm run dev command. I don’t see that webpack-dev-server is used in the project, how do you make changes and develop? Please guide me on this issue.
  2. Please tell me if there is technical documentation for this project. I can only find user documentation that does not contain technical information about certain methods of the interface.

Thank you!
