-
-Custom Resources support `/status` and `/scale` subresources as a [beta feature](https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/#subresources) in v1.11 and is enabled by default.

-The CRD in [`crd-status-subresource.yaml`](./artifacts/examples/crd-status-subresource.yaml) enables the `/status` subresource
-for custom resources.
-This means that [`UpdateStatus`](./controller.go#L330) can be used by the controller to update only the status part of the custom resource.
-
-To understand why only the status part of the custom resource should be updated, please refer to the [Kubernetes API conventions](https://git.k8s.io/community/contributors/devel/api-conventions.md#spec-and-status).

-# client-go under the hood
-
-The [client-go](https://github.com/kubernetes/client-go/) library contains various mechanisms that you can use when 
-developing your custom controllers. These mechanisms are defined in the 
-[tools/cache folder](https://github.com/kubernetes/client-go/tree/master/tools/cache) of the library.
-
-Here is a pictorial representation showing how the various components in 
-the client-go library work and their interaction points with the custom 
-controller code that you will write.
-
-<p align="center">
-  <img src="images/client-go-controller-interaction.jpeg" height="600" width="700"/>
-</p>
-
-## client-go components
-
-* Reflector: A reflector, which is defined in [type *Reflector* inside package *cache*](https://github.com/kubernetes/client-go/blob/master/tools/cache/reflector.go),
-watches the Kubernetes API for the specified resource type (kind).
-The function in which this is done is *ListAndWatch*.
-The watch could be for an in-built resource or it could be for a custom resource.
-When the reflector receives notification about existence of new
-resource instance through the watch API, it gets the newly created object 
-using the corresponding listing API and puts it in the Delta Fifo queue
-inside the *watchHandler* function.
-
-
-* Informer: An informer defined in the [base controller inside package *cache*](https://github.com/kubernetes/client-go/blob/master/tools/cache/controller.go) pops objects from the Delta Fifo queue.
-The function in which this is done is *processLoop*. The job of this base controller
-is to save the object for later retrieval, and to invoke our controller passing it the object.
-
-* Indexer: An indexer provides indexing functionality over objects.
-It is defined in [type *Indexer* inside package *cache*](https://github.com/kubernetes/client-go/blob/master/tools/cache/index.go). A typical indexing use-case is to create an index based on object labels. Indexer can
-maintain indexes based on several indexing functions.
-Indexer uses a thread-safe data store to store objects and their keys.
-There is a default function named *MetaNamespaceKeyFunc* defined in [type Store inside package cache](https://github.com/kubernetes/client-go/blob/master/tools/cache/store.go)
-that generates an object’s key as `<namespace>/<name>` combination for that object.
-
-
-## Custom Controller components
-
-* Informer reference: This is the reference to the Informer instance that knows 
-how to work with your custom resource objects. Your custom controller code needs 
-to create the appropriate Informer.
-
-* Indexer reference: This is the reference to the Indexer instance that knows 
-how to work with your custom resource objects. Your custom controller code needs 
-to create this. You will be using this reference for retrieving objects for 
-later processing.
-
-The base controller in client-go provides the *NewIndexerInformer* function to create Informer and Indexer.
-In your code you can either [directly invoke this function](https://github.com/kubernetes/client-go/blob/master/examples/workqueue/main.go#L174) or [use factory methods for creating an informer.](https://github.com/kubernetes/sample-controller/blob/master/main.go#L61)
-
-* Resource Event Handlers: These are the callback functions which will be called by 
-the Informer when it wants to deliver an object to your controller. The typical 
-pattern to write these functions is to obtain the dispatched object’s key
-and enqueue that key in a work queue for further processing.
-
-* Work queue: This is the queue that you create in your controller code to decouple 
-delivery of an object from its processing. Resource event handler functions are written 
-to extract the delivered object’s key and add that to the work queue.
-
-* Process Item: This is the function that you create in your code which processes items 
-from the work queue. There can be one or more other functions that do the actual processing. 
-These functions will typically use the [Indexer reference](https://github.com/kubernetes/client-go/blob/master/examples/workqueue/main.go#L73), or a Listing wrapper to retrieve the object corresponding to the key.

-# JSON-Patch
-`jsonpatch` is a library which provides functionallity for both applying
-[RFC6902 JSON patches](http://tools.ietf.org/html/rfc6902) against documents, as
-well as for calculating & applying [RFC7396 JSON merge patches](https://tools.ietf.org/html/rfc7396).

-# Get It!

-**Latest and greatest**: 
-```bash
-go get -u github.com/evanphx/json-patch
-```
-
-**Stable Versions**:
-* Version 4: `go get -u gopkg.in/evanphx/json-patch.v4`
-
-(previous versions below `v3` are unavailable)
-
-# Use It!
-* [Create and apply a merge patch](#create-and-apply-a-merge-patch)
-* [Create and apply a JSON Patch](#create-and-apply-a-json-patch)
-* [Comparing JSON documents](#comparing-json-documents)
-* [Combine merge patches](#combine-merge-patches)
-
-
-# Configuration
-
-* There is a global configuration variable `jsonpatch.SupportNegativeIndices`.
-  This defaults to `true` and enables the non-standard practice of allowing
-  negative indices to mean indices starting at the end of an array. This
-  functionality can be disabled by setting `jsonpatch.SupportNegativeIndices =
-  false`.
-
-* There is a global configuration variable `jsonpatch.AccumulatedCopySizeLimit`,
-  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.
-
-## 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. 
-
-It can describe the changes needed to convert from the original to the 
-modified JSON document.
-
-Once you have a merge patch, you can apply it to other JSON documents using the
-`jsonpatch.MergePatch(document, patch)` function.
-
-```go
-package main
-
-import (
-	"fmt"
-
-	jsonpatch "github.com/evanphx/json-patch"
-)
-
-func main() {
-	// Let's create a merge patch from these two documents...
-	original := []byte(`{"name": "John", "age": 24, "height": 3.21}`)
-	target := []byte(`{"name": "Jane", "age": 24}`)
-
-	patch, err := jsonpatch.CreateMergePatch(original, target)
-	if err != nil {
-		panic(err)
-	}
-
-	// Now lets apply the patch against a different JSON document...
-
-	alternative := []byte(`{"name": "Tina", "age": 28, "height": 3.75}`)
-	modifiedAlternative, err := jsonpatch.MergePatch(alternative, patch)
-
-	fmt.Printf("patch document:   %s\n", patch)
-	fmt.Printf("updated alternative doc: %s\n", modifiedAlternative)
-}
-```
-
-When ran, you get the following output:
-
-```bash
-$ go run main.go
-patch document:   {"height":null,"name":"Jane"}
-updated tina doc: {"age":28,"name":"Jane"}
-```
-
-## Create and apply a JSON Patch
-You can create patch objects using `DecodePatch([]byte)`, which can then 
-be applied against JSON documents.
-
-The following is an example of creating a patch from two operations, and
-applying it against a JSON document.
-
-```go
-package main
-
-import (
-	"fmt"
-
-	jsonpatch "github.com/evanphx/json-patch"
-)
-
-func main() {
-	original := []byte(`{"name": "John", "age": 24, "height": 3.21}`)
-	patchJSON := []byte(`[
-		{"op": "replace", "path": "/name", "value": "Jane"},
-		{"op": "remove", "path": "/height"}
-	]`)
-
-	patch, err := jsonpatch.DecodePatch(patchJSON)
-	if err != nil {
-		panic(err)
-	}
-
-	modified, err := patch.Apply(original)
-	if err != nil {
-		panic(err)
-	}
-
-	fmt.Printf("Original document: %s\n", original)
-	fmt.Printf("Modified document: %s\n", modified)
-}
-```
-
-When ran, you get the following output:
-
-```bash
-$ go run main.go
-Original document: {"name": "John", "age": 24, "height": 3.21}
-Modified document: {"age":24,"name":"Jane"}
-```
-
-## Comparing JSON documents
-Due to potential whitespace and ordering differences, one cannot simply compare
-JSON strings or byte-arrays directly. 
-
-As such, you can instead use `jsonpatch.Equal(document1, document2)` to 
-determine if two JSON documents are _structurally_ equal. This ignores
-whitespace differences, and key-value ordering.
-
-```go
-package main
-
-import (
-	"fmt"
-
-	jsonpatch "github.com/evanphx/json-patch"
-)
-
-func main() {
-	original := []byte(`{"name": "John", "age": 24, "height": 3.21}`)
-	similar := []byte(`
-		{
-			"age": 24,
-			"height": 3.21,
-			"name": "John"
-		}
-	`)
-	different := []byte(`{"name": "Jane", "age": 20, "height": 3.37}`)
-
-	if jsonpatch.Equal(original, similar) {
-		fmt.Println(`"original" is structurally equal to "similar"`)
-	}
-
-	if !jsonpatch.Equal(original, different) {
-		fmt.Println(`"original" is _not_ structurally equal to "similar"`)
-	}
-}
-```
-
-When ran, you get the following output:
-```bash
-$ go run main.go
-"original" is structurally equal to "similar"
-"original" is _not_ structurally equal to "similar"
-```
-
-## Combine merge patches
-Given two JSON merge patch documents, it is possible to combine them into a 
-single merge patch which can describe both set of changes.
-
-The resulting merge patch can be used such that applying it results in a
-document structurally similar as merging each merge patch to the document
-in succession. 
-
-```go
-package main
-
-import (
-	"fmt"
-
-	jsonpatch "github.com/evanphx/json-patch"
-)
-
-func main() {
-	original := []byte(`{"name": "John", "age": 24, "height": 3.21}`)
-
-	nameAndHeight := []byte(`{"height":null,"name":"Jane"}`)
-	ageAndEyes := []byte(`{"age":4.23,"eyes":"blue"}`)
-
-	// Let's combine these merge patch documents...
-	combinedPatch, err := jsonpatch.MergeMergePatches(nameAndHeight, ageAndEyes)
-	if err != nil {
-		panic(err)
-	}
-
-	// Apply each patch individual against the original document
-	withoutCombinedPatch, err := jsonpatch.MergePatch(original, nameAndHeight)
-	if err != nil {
-		panic(err)
-	}
-
-	withoutCombinedPatch, err = jsonpatch.MergePatch(withoutCombinedPatch, ageAndEyes)
-	if err != nil {
-		panic(err)
-	}
-
-	// Apply the combined patch against the original document
-
-	withCombinedPatch, err := jsonpatch.MergePatch(original, combinedPatch)
-	if err != nil {
-		panic(err)
-	}
-
-	// Do both result in the same thing? They should!
-	if jsonpatch.Equal(withCombinedPatch, withoutCombinedPatch) {
-		fmt.Println("Both JSON documents are structurally the same!")
-	}
-
-	fmt.Printf("combined merge patch: %s", combinedPatch)
-}
-```
-
-When ran, you get the following output:
-```bash
-$ go run main.go
-Both JSON documents are structurally the same!
-combined merge patch: {"age":4.23,"eyes":"blue","height":null,"name":"Jane"}
-```
-
-# CLI for comparing JSON documents
-You can install the commandline program `json-patch`.
-
-This program can take multiple JSON patch documents as arguments, 
-and fed a JSON document from `stdin`. It will apply the patch(es) against 
-the document and output the modified doc.
-
-**patch.1.json**
-```json
-[
-    {"op": "replace", "path": "/name", "value": "Jane"},
-    {"op": "remove", "path": "/height"}
-]
-```
-
-**patch.2.json**
-```json
-[
-    {"op": "add", "path": "/address", "value": "123 Main St"},
-    {"op": "replace", "path": "/age", "value": "21"}
-]
-```
-
-**document.json**
-```json
-{
-    "name": "John",
-    "age": 24,
-    "height": 3.21
-}
-```
-
-You can then run:
-
-```bash
-$ go install github.com/evanphx/json-patch/cmd/json-patch
-$ cat document.json | json-patch -p patch.1.json -p patch.2.json
-{"address":"123 Main St","age":"21","name":"Jane"}

 ## Introduction
 
-A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
+A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs. 
 
 In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
 
 ## Compatibility
 
-This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
