# Inside The Machine · one-command install: Make images
# Pictures from a text prompt, made on your own computer. No credits, no upload.
# Page: https://insidethemachine.ai/do/images   Agent doc: https://insidethemachine.ai/install/images.md
# Run status: Not run: taken from the README, not checked. Point-and-click apps (Draw Things, ComfyUI). The script only checks and prints where to get them.
# This script: The wrapper scripts are generated from the site data. Every .sh passed bash -n and shellcheck and ran in plan mode on Linux (Debian 13). Every .ps1 passed the PowerShell parser and chat.ps1 ran in plan, verify and rollback mode under PowerShell 7 on Linux with Windows calls mocked. Not run on macOS or real Windows.

#   curl -fsSL https://insidethemachine.ai/install/images.sh | bash                        install, then check

#   curl -fsSL https://insidethemachine.ai/install/images.sh | bash -s -- verify           only the checks
#   curl -fsSL https://insidethemachine.ai/install/images.sh | bash -s -- rollback --yes   undo it (without --yes it only prints)
