git clone [--template=<template_directory>]
    [-l] [-s] [--no-hardlinks] [-q] [-n] [--bare] [--mirror]
    [-o <name>] [-b <name>] [-u <upload-pack>] [--reference <repository>]
    [--dissociate] [--separate-git-dir <git dir>]
    [--depth <depth>] [--[no-]single-branch] [--no-tags]
    [--recurse-submodules] [--[no-]shallow-submodules]
    [--jobs <n>] [--] <repository> [<directory>]


--local, -l
    When the repository to clone from is on a local machine, this flag bypasses the normal "Git aware" transport mechanism and clones
    the repository by making a copy of HEAD and everything under objects and refs directories. The files under .git/objects/ directory
    are hardlinked to save space when possible.

    If the repository is specified as a local path (e.g., /path/to/repo), this is the default, and --local is essentially a no-op. If
    the repository is specified as a URL, then this flag is ignored (and we never use the local optimizations). Specifying --no-local
    will override the default when /path/to/repo is given, using the regular Git transport instead.

    Force the cloning process from a repository on a local filesystem to copy the files under the .git/objects directory instead of
    using hardlinks. This may be desirable if you are trying to make a back-up of your repository.

--shared, -s
    When the repository to clone is on the local machine, instead of using hard links, automatically setup .git/objects/info/alternates
    to share the objects with the source repository. The resulting repository starts out without any object of its own.

    NOTE: this is a possibly dangerous operation; do not use it unless you understand what it does. If you clone your repository using
    this option and then delete branches (or use any other Git command that makes any existing commit unreferenced) in the source
    repository, some objects may become unreferenced (or dangling). These objects may be removed by normal Git operations (such as git
    commit) which automatically call git gc --auto. (See git-gc(1).) If these objects are removed and were referenced by the cloned
    repository, then the cloned repository will become corrupt.

    Note that running git repack without the -l option in a repository cloned with -s will copy objects from the source repository into
    a pack in the cloned repository, removing the disk space savings of clone -s. It is safe, however, to run git gc, which uses the -l
    option by default.

    If you want to break the dependency of a repository cloned with -s on its source repository, you can simply run git repack -a to
    copy all objects from the source repository into a pack in the cloned repository.

--reference[-if-able] <repository>
    If the reference repository is on the local machine, automatically setup .git/objects/info/alternates to obtain objects from the
    reference repository. Using an already existing repository as an alternate will require fewer objects to be copied from the
    repository being cloned, reducing network and local storage costs. When using the --reference-if-able, a non existing directory is
    skipped with a warning instead of aborting the clone.

    NOTE: see the NOTE for the --shared option, and also the --dissociate option.

    Borrow the objects from reference repositories specified with the --reference options only to reduce network transfer, and stop
    borrowing from them after a clone is made by making necessary local copies of borrowed objects. This option can also be used when
    cloning locally from a repository that already borrows objects from another repository--the new repository will borrow objects from
    the same repository, and this option can be used to stop the borrowing.

--quiet, -q
    Operate quietly. Progress is not reported to the standard error stream.

--verbose, -v
    Run verbosely. Does not affect the reporting of progress status to the standard error stream.

    Progress status is reported on the standard error stream by default when it is attached to a terminal, unless -q is specified. This
    flag forces progress status even if the standard error stream is not directed to a terminal.

--no-checkout, -n
    No checkout of HEAD is performed after the clone is complete.

    Make a bare Git repository. That is, instead of creating <directory> and placing the administrative files in <directory>/.git, make
    the <directory> itself the $GIT_DIR. This obviously implies the -n because there is nowhere to check out the working tree. Also the
    branch heads at the remote are copied directly to corresponding local branch heads, without mapping them to refs/remotes/origin/.
    When this option is used, neither remote-tracking branches nor the related configuration variables are created.

    Set up a mirror of the source repository. This implies --bare. Compared to --bare, --mirror not only maps local branches of the
    source to local branches of the target, it maps all refs (including remote-tracking branches, notes etc.) and sets up a refspec
    configuration such that all these refs are overwritten by a git remote update in the target repository.

--origin <name>, -o <name>
    Instead of using the remote name origin to keep track of the upstream repository, use <name>.

--branch <name>, -b <name>
    Instead of pointing the newly created HEAD to the branch pointed to by the cloned repository's HEAD, point to <name> branch
    instead. In a non-bare repository, this is the branch that will be checked out.  --branch can also take tags and detaches the HEAD
    at that commit in the resulting repository.

--upload-pack <upload-pack>, -u <upload-pack>
    When given, and the repository to clone from is accessed via ssh, this specifies a non-default path for the command run on the
    other end.

    Specify the directory from which templates will be used; (See the "TEMPLATE DIRECTORY" section of git-init(1).)

--config <key>=<value>, -c <key>=<value>
    Set a configuration variable in the newly-created repository; this takes effect immediately after the repository is initialized,
    but before the remote history is fetched or any files checked out. The key is in the same format as expected by git-config(1)
    (e.g., core.eol=true). If multiple values are given for the same key, each value will be written to the config file. This makes it
    safe, for example, to add additional fetch refspecs to the origin remote.

--depth <depth>
    Create a shallow clone with a history truncated to the specified number of commits. Implies --single-branch unless
    --no-single-branch is given to fetch the histories near the tips of all branches. If you want to clone submodules shallowly, also
    pass --shallow-submodules.

    Create a shallow clone with a history after the specified time.

    Create a shallow clone with a history, excluding commits reachable from a specified remote branch or tag. This option can be
    specified multiple times.

    Clone only the history leading to the tip of a single branch, either specified by the --branch option or the primary branch
    remote's HEAD points at. Further fetches into the resulting repository will only update the remote-tracking branch for the branch
    this option was used for the initial cloning. If the HEAD at the remote did not point at any branch when --single-branch clone was
    made, no remote-tracking branch is created.

    Don't clone any tags, and set remote.<remote>.tagOpt=--no-tags in the config, ensuring that future git pull and git fetch
    operations won't follow any tags. Subsequent explicit tag fetches will still work, (see git-fetch(1)).

    Can be used in conjunction with --single-branch to clone and maintain a branch with no references other than a single cloned
    branch. This is useful e.g. to maintain minimal clones of the default branch of some repository for search indexing.

    After the clone is created, initialize and clone submodules within based on the provided pathspec. If no pathspec is provided, all
    submodules are initialized and cloned. Submodules are initialized and cloned using their default settings. The resulting clone has set to the provided pathspec, or "." (meaning all submodules) if no pathspec is provided. This is equivalent to
    running git submodule update --init --recursive immediately after the clone is finished. This option is ignored if the cloned
    repository does not have a worktree/checkout (i.e. if any of --no-checkout/-n, --bare, or --mirror is given)

    All submodules which are cloned will be shallow with a depth of 1.

--separate-git-dir=<git dir>
    Instead of placing the cloned repository where it is supposed to be, place the cloned repository at the specified directory, then
    make a filesystem-agnostic Git symbolic link to there. The result is Git repository can be separated from working tree.

-j <n>, --jobs <n>
    The number of submodules fetched at the same time. Defaults to the submodule.fetchJobs option.

    The (possibly remote) repository to clone from. See the URLS section below for more information on specifying repositories.

    The name of a new directory to clone into. The "humanish" part of the source repository is used if no directory is explicitly given
    (repo for /path/to/repo.git and foo for host.xz:foo/.git). Cloning into an existing directory is only allowed if the directory is
