+NAME
+----
+git-restore - Restore working tree files
+
+SYNOPSIS
+--------
+[verse]
+'git restore' [<options>] [--source=<tree>] [--staged] [--worktree] <pathspec>...
+'git restore' (-p|--patch) [<options>] [--source=<tree>] [--staged] [--worktree] [<pathspec>...]
+
+DESCRIPTION
+-----------
+Restore specified paths in the working tree with some contents from a
+restore source. If a path is tracked but does not exist in the restore
+source, it will be removed to match the source.
+
+The command can also be used to restore the content in the index with
+`--staged`, or restore both the working tree and the index with
+`--staged --worktree`.
+
+By default, the restore sources for working tree and the index are the
+index and `HEAD` respectively. `--source` could be used to specify a
+commit as the restore source.
+
+See "Reset, restore and revert" in linkgit:git[1] for the differences
+between the three commands.
+
+THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
+
+OPTIONS
+-------
+-s <tree>::
+--source=<tree>::
+	Restore the working tree files with the content from the given
+	tree. It is common to specify the source tree by naming a
+	commit, branch or tag associated with it.
++
+If not specified, the default restore source for the working tree is
+the index, and the default restore source for the index is
+`HEAD`. When both `--staged` and `--worktree` are specified,
+`--source` must also be specified.
+
+-p::
+--patch::
+	Interactively select hunks in the difference between the
+	restore source and the restore location. See the ``Interactive
+	Mode'' section of linkgit:git-add[1] to learn how to operate
+	the `--patch` mode.
++
+Note that `--patch` can accept no pathspec and will prompt to restore
+all modified paths.
+
+-W::
+--worktree::
+-S::
+--staged::
+	Specify the restore location. If neither option is specified,
+	by default the working tree is restored. Specifying `--staged`
+	will only restore the index. Specifying both restores both.
+
+-q::
+--quiet::
+	Quiet, suppress feedback messages. Implies `--no-progress`.
+
+--progress::
+--no-progress::
+	Progress status is reported on the standard error stream
+	by default when it is attached to a terminal, unless `--quiet`
+	is specified. This flag enables progress reporting even if not
+	attached to a terminal, regardless of `--quiet`.
+
+--ours::
+--theirs::
+	When restoring files in the working tree from the index, use
+	stage #2 ('ours') or #3 ('theirs') for unmerged paths.
++
+Note that during `git rebase` and `git pull --rebase`, 'ours' and
+'theirs' may appear swapped. See the explanation of the same options
+in linkgit:git-checkout[1] for details.
+
+-m::
+--merge::
+	When restoring files on the working tree from the index,
+	recreate the conflicted merge in the unmerged paths.
+
+--conflict=<style>::
+	The same as `--merge` option above, but changes the way the
+	conflicting hunks are presented, overriding the
+	`merge.conflictStyle` configuration variable.  Possible values
+	are "merge" (default) and "diff3" (in addition to what is
+	shown by "merge" style, shows the original contents).
+
+--ignore-unmerged::
+	When restoring files on the working tree from the index, do
+	not abort the operation if there are unmerged entries and
+	neither `--ours`, `--theirs`, `--merge` or `--conflict` is
+	specified. Unmerged paths on the working tree are left alone.
+
+--ignore-skip-worktree-bits::
+	In sparse checkout mode, by default is to only update entries
+	matched by `<pathspec>` and sparse patterns in
+	$GIT_DIR/info/sparse-checkout. This option ignores the sparse
+	patterns and unconditionally restores any files in
+	`<pathspec>`.
+
+--overlay::
+--no-overlay::
+	In overlay mode, the command never removes files when
+	restoring. In no-overlay mode, tracked files that do not
+	appear in the `--source` tree are removed, to make them match
+	`<tree>` exactly. The default is no-overlay mode.
+
+EXAMPLES
+--------
+
+The following sequence switches to the `master` branch, reverts the
+`Makefile` to two revisions back, deletes hello.c by mistake, and gets
+it back from the index.
+
+------------
+$ git switch master
+$ git restore --source master~2 Makefile  <1>
+$ rm -f hello.c
+$ git restore hello.c                     <2>
+------------
+
+<1> take a file out of another commit
+<2> restore hello.c from the index
+
+If you want to restore _all_ C source files to match the version in
+the index, you can say
+
+------------
+$ git restore '*.c'
+------------
+
+Note the quotes around `*.c`.  The file `hello.c` will also be
+restored, even though it is no longer in the working tree, because the
+file globbing is used to match entries in the index (not in the
+working tree by the shell).
+
+To restore all files in the current directory
+
+------------
+$ git restore .
+------------
+
+or to restore all working tree files with 'top' pathspec magic (see
+linkgit:gitglossary[7])
+
+------------
+$ git restore :/
+------------
+
+To restore a file in the index to match the version in `HEAD` (this is
+the same as using linkgit:git-reset[1])
+
+------------
+$ git restore --staged hello.c
+------------
+
+or you can restore both the index and the working tree (this the same
+as using linkgit:git-checkout[1])
+
+------------
+$ git restore --source=HEAD --staged --worktree hello.c
+------------
+
+or the short form which is more practical but less readable:
+
+------------
+$ git restore -s@ -SW hello.c
+------------
