git-subtree: Add a Git repository as a subtree.

$ git subtree add --prefix=${path-to-directory-} --squash ${repository_url} ${branch_name}

try on your machine

The git subtree add command is used to integrate a separate Git repository into your current repository as a subdirectory. Here's a breakdown of the command:

--prefix=${path-to-directory-} specifies the subdirectory path in your current repository where you want to add the contents of the external repository. Replace ${path-to-directory-} with the desired path.
--squash option tells Git to squash all the commits from the external repository into a single commit, simplifying the history in your current repository.
${repository_url} is the URL of the external repository that you want to add as a subtree. Replace it with the actual URL.
${branch_name} is the name of the branch in the external repository that you want to integrate. Replace it with the desired branch name.

When you run this command, Git will fetch the contents of the external repository, squash its commit history (if --squash option is used), and merge it into your current repository as a subdirectory specified by ${path-to-directory-}.
