+    Kind for all vector objects in SymPy.
+
+    Parameters
+    ==========
+
+    element_kind : Kind
+        Kind of the element. Default is
+        :class:`sympy.core.kind.NumberKind`,
+        which means that the vector contains only numbers.
+
+    Examples
+    ========
+
+    Any instance of Vector class has kind ``VectorKind``:
+
+    >>> from sympy.vector.coordsysrect import CoordSys3D
+    >>> Sys = CoordSys3D('Sys')
+    >>> Sys.i.kind
+    VectorKind(NumberKind)
+
+    Operations between instances of Vector keep also have the kind ``VectorKind``:
+
+    >>> from sympy.core.add import Add
+    >>> v1 = Sys.i * 2 + Sys.j * 3 + Sys.k * 4
+    >>> v2 = Sys.i * Sys.x + Sys.j * Sys.y + Sys.k * Sys.z
+    >>> v1.kind
+    VectorKind(NumberKind)
+    >>> v2.kind
+    VectorKind(NumberKind)
+    >>> Add(v1, v2).kind
+    VectorKind(NumberKind)
+
+    Subclasses of Vector also have the kind ``VectorKind``, such as
+    Cross, VectorAdd, VectorMul or VectorZero.
