+# git mktree
+
+> Build a tree object using `ls-tree` formatted text.
+> More information: <https://git-scm.com/docs/git-mktree>.
+
+- Build a tree object and verify that each tree entry’s hash identifies an existing object:
+
+`git mktree`
+
+- Allow missing objects:
+
+`git mktree --missing`
+
+- Read the NUL ([z]ero character) terminated output of the tree object (`ls-tree -z`):
+
+`git mktree -z`
+
+- Allow the creation of multiple tree objects:
+
+`git mktree --batch`
+
+- Sort and build a tree from `stdin` (non-recursive `git ls-tree` output format is required):
+
+`git mktree < {{path/to/tree.txt}}`
