+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.
+
+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 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
+------------

+Reset, restore and revert
+~~~~~~~~~~~~~~~~~~~~~~~~~
+There are three commands with similar names: `git reset`,
+`git restore` and `git revert`.
+
+* linkgit:git-revert[1] is about making a new commit that reverts the
+ changes made by other commits.
+
+* linkgit:git-restore[1] is about restoring files in the working tree
+ from either the index or another commit. This command does not
+ update your branch. The command can also be used to restore files in
+ the index from another commit.
+
+* linkgit:git-reset[1] is about updating your branch, moving the tip
+ in order to add or remove commits from the branch. This operation
+ changes the commit history.
++
+`git reset` can also be used to restore the index, overlapping with
+`git restore`.

+Some other commands that also work on files in the working tree and/or
+in the index can take `--staged` and/or `--worktree`.
+
+* `--staged` is exactly like `--cached`, which is used to ask a
