 ## kubectl integration
 
-The kustomize build flow at [v2.0.3] was added
-to [kubectl v1.14][kubectl announcement].  The kustomize
-flow in kubectl has remained frozen at v2.0.3 while work
-to extract kubectl from the k/k repo, and work to remove
-kustomize's dependence on core k/k code ([#2506]) has proceeded.
-The reintegration effort is tracked in [#1500] (and its blocking
-issues).
+Since [v1.14][kubectl announcement] the kustomize build system has been included in kubectl.

-//   The field will be added and the value inserted.

-//   this  is an Add operation.  In contrast, a Replace operation

-//   TODO: Modify kyaml/yaml/PathGetter to allow this.
-//   The value will be inserted into the array at the given position,
-//   shifting other contents. To instead replace an array entry, use
-//   an implementation of an IETF RFC 6902 Replace operation.
-//
-// For the common case of a filepath in the field value, and a desire

-	// At the time of writing, Value's value should be a simple string,

-
-	// FieldPath is a JSON-style path to the field intended to hold the value.

-	// Call the value of this field _i_.
-	//
-	//   If _i_ is zero, negative or unspecified, this field has no effect.
-	//
-	//   If _i_ is > 0, then it's assumed that
-	//   - 'Value' is a string that can work as a directory or file name,
-	//   - the field value intended for replacement holds a filepath.
-	//
-	// The filepath is split into a string slice, the value is inserted
-	// at position [i-1], shifting the rest of the path to the right.
-	// A value of i==1 puts the new value at the start of the path.
-	// This change never converts an absolute path to a relative path,
-	// meaning adding a new field at position i==1 will preserve a
-	// leading slash. E.g. if Value == 'PEACH'
