The first content for your repository for the state of the '$_BOOT_DOMAIN' domain has been created.

Please create a states repository.

Maybe you can use https and user password for pushing the first commit.

Then go to folder '/tmp/skeleton/state' and follow the instructions as your git server shows.
For example:

  cd /tmp/skeleton/state
  git init
  git checkout -b main
  git add .
  git commit -m "first state"
  git remote add origin https://git.example.dev/[SOME_PATH/]$_REOPSITORY_NAME.git
  git push -u origin main
