## Project history and usage

create-dmg is a macOS command-line packaging helper for producing polished disk images from a source folder. It wraps standard macOS disk-image tooling with options for Finder window layout, icons, background images, Applications drop links, encryption, signing, and notarization.

### Project history

The project README credits Andrey Tarantsov as the original creator and says Andrew Janke helped substantially with the project in May 2020. The project is maintained as a shell script in a public GitHub repository under the create-dmg organization.

### Adoption history

The README documents Homebrew installation as the first installation path, followed by release downloads and cloning the repository. That distribution style made create-dmg convenient for macOS developers who wanted repeatable DMG creation in release scripts without maintaining their own AppleScript and hdiutil wrappers.

### How it is used

The normal workflow is to run create-dmg with an output .dmg name and a source folder, then pass options for volume name, icon placement, background art, filesystem format, encryption, codesigning, notarization, and related macOS packaging details.

### Why package nerds care

For package maintainers, create-dmg matters because DMG layout is a macOS distribution detail that is easy to get wrong and awkward to reproduce. The tool packages common release-engineering conventions into one script that Homebrew, MacPorts, and Nix can expose as a small CLI dependency.
