Don't understand why this heading mention git

https://github.com/rust-embedded/book/blob/01327046e391d59de5de0079df30d1b57533e9da/src/intro/tooling.md#cargo-generate-or-git

only reference i see that it can be used as a download tools. But since there are more download tools they could all be put in the heading as well.

please clarify
