Subtree

Definitions

1. In data structures, any node and all its descendants within a tree. In Git, `git subtree` is an alternative to submodules that merges an external repository's history directly into a subdirectory of the host repo, allowing contributions without requiring collaborators to understand submodule workflows.

   In plain English: A branch of a tree structure including everything below it, or a Git feature that folds another project into a folder of your repo.

   Example: "We pulled the shared library in with git subtree so contributors can just clone and go — no submodule init dance."
