wtf is buildpack-deps?

This repository holds the source files for an official Docker image called buildpack-deps. Docker images are essentially pre-packaged software environments that run consistently across different computers, and this project provides a foundational starting point that bundles together common development tools so other images don't have to install them from scratch every time. At a practical level, it gathers things like Git, curl, and basic compilation tools into a single reusable package. Think of it as a pre-stocked toolbox. If you are building a more complex software environment, you can start from this base instead of hunting down and installing each utility on your own. It exists in a few variations, like one with just the essentials and another with a more complete set of tools, so you can pick the right level of depth for your needs. The people who use this are typically developers or teams creating custom Docker images for their own applications. For example, if you are packaging a Python or Ruby app and need to download dependencies, compile some native code, or pull source files from a version control system, starting with this base saves you from writing the same setup commands repeatedly. It is a building block meant to be stacked on, not a finished product you run directly. The README itself is quite minimal. It points readers to a separate documentation repository for the full instructions on usage, contributing, and reporting issues. The project is maintained as part of the official Docker library, which means it follows a shared set of standards and review processes used across many widely-trusted base images.
