Where is configuartion.yaml file location?

Hi, I am a beginner and want to develop a component. I have followed the documentation and run it locally -> http://localhost:8123

I want to add logger component, but unable to find configuartion.yaml. Am I setting it up wrongly?

It might be linked to me unable to set up a remote container: Issue entering Remote-Containers

I would recommend to install samba service to get access to the directories. Or install the editor (https://www.home-assistant.io/getting-started/configuration/) and you can access to the configuration.yaml via the GUI of Home Assistant.

Solved! After setting up development environment hass. It create config file at /Users/<User name>/.homeassistant/configuration.yaml for mac users.
