 When you have all the necessary dependencies, you can go ahead and grab the latest tagged release tarball from several places.
 You can get it via the Kernel.org site, at https://www.kernel.org/pub/software/scm/git[], or the mirror on the GitHub web site, at https://github.com/git/git/releases[].
 It's generally a little clearer what the latest version is on the GitHub page, but the kernel.org page also has release signatures if you want to verify your download.
