DNC_MD_CONTENT = """# dnc

This project uses dnc (dockernecontainer). When `.dnc` is present,
run ALL commands inside the container by prefixing them with `dnc -`:

  dnc - nvim
  dnc - npm install
  dnc - python manage.py migrate

## Config

User config lives in `~/.config/dnc/` (mounted at `/run/host/config/`).
Images can read `/run/host/config/dnc.toml` for colors, keybinds, etc.

## Git / SSH

SSH agent socket is forwarded automatically. SSH keys from `~/.ssh/`
and gitconfig from `~/.gitconfig` are available inside the container.
git push/pull works without additional setup.
