   which limits the total size increase in bytes caused by "copy" operations in a
   patch. It defaults to 0, which means there is no limit.
 
+These global variables control the behavior of `jsonpatch.Apply`.
+
+An alternative to `jsonpatch.Apply` is `jsonpatch.ApplyWithOptions` whose behavior
+is controlled by an `options` parameter of type `*jsonpatch.ApplyOptions`.
+
+Structure `jsonpatch.ApplyOptions` includes the configuration options above 
+and adds two new options: `AllowMissingPathOnRemove` and `EnsurePathExistsOnAdd`.
+
+When `AllowMissingPathOnRemove` is set to `true`, `jsonpatch.ApplyWithOptions` will ignore
+`remove` operations whose `path` points to a non-existent location in the JSON document.
+`AllowMissingPathOnRemove` defaults to `false` which will lead to `jsonpatch.ApplyWithOptions`
+returning an error when hitting a missing `path` on `remove`.
+
+When `EnsurePathExistsOnAdd` is set to `true`, `jsonpatch.ApplyWithOptions` will make sure
+that `add` operations produce all the `path` elements that are missing from the target object.
+
+Use `jsonpatch.NewApplyOptions` to create an instance of `jsonpatch.ApplyOptions`
+whose values are populated from the global configuration variables.

 ## Create and apply a merge patch
 Given both an original JSON document and a modified JSON document, you can create
 a [Merge Patch](https://tools.ietf.org/html/rfc7396) document.
