When you export a note for the first time, Obsidian Plugin will ask you to specify the kit folder (the folder where you want your notes to be exported). You have to provide an absolute url to the folder.
It will create a kitrc.md at the root of your vault, containing the global configuration of your kit. Learn about the kitrc file.
