${COLOR_RESET}
Welcome to your development container!
This is how you can work with it:
- Run \`${COLOR_CYAN}${RUN_CMD}${COLOR_RESET}\` to start validator
- ${COLOR_CYAN}Files will be synchronized${COLOR_RESET} between your local machine and this container

If you wish to run validator in the debug mode with delve, run:
  \`${COLOR_CYAN}${DEBUG_CMD}${COLOR_RESET}\`
  Wait until the \`${COLOR_CYAN}API server listening at: [::]:2342${COLOR_RESET}\` message appears
  Start the \"Debug (localhost:2342)\" configuration in VSCode to connect your debugger session.
  ${COLOR_CYAN}Note:${COLOR_RESET} validator won't start until you connect with the debugger.
  ${COLOR_CYAN}Note:${COLOR_RESET} validator will be stopped once you detach your debugger session.

${COLOR_CYAN}TIP:${COLOR_RESET} hit an up arrow on your keyboard to find the commands mentioned above :)
