-### Namespace filtering
-
-The following strategies accept a `namespaces` parameter which allows to specify a list of including, resp. excluding namespaces:
-* `PodLifeTime`
-* `RemovePodsHavingTooManyRestarts`
-* `RemovePodsViolatingNodeTaints`
-* `RemovePodsViolatingNodeAffinity`
-* `RemovePodsViolatingInterPodAntiAffinity`
-* `RemoveDuplicates`
-* `RemovePodsViolatingTopologySpreadConstraint`
-

-```yaml
-apiVersion: "descheduler/v1alpha1"

-strategies:
-  "PodLifeTime":

-     params:
-        podLifeTime:
-          maxPodLifeTimeSeconds: 86400
-        namespaces:
-          include:
-          - "namespace1"
-          - "namespace2"
-```
-
-In the examples `PodLifeTime` gets executed only over `namespace1` and `namespace2`.
-The similar holds for `exclude` field:

-```yaml
-apiVersion: "descheduler/v1alpha1"

-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:

-        namespaces:
-          exclude:
-          - "namespace1"
-          - "namespace2"
-```
-
-The strategy gets executed over all namespaces but `namespace1` and `namespace2`.
-
-It's not allowed to compute `include` with `exclude` field.
-
-### Priority filtering
-
-All strategies are able to configure a priority threshold, only pods under the threshold can be evicted. You can
-specify this threshold by setting `thresholdPriorityClassName`(setting the threshold to the value of the given
-priority class) or `thresholdPriority`(directly setting the threshold) parameters. By default, this threshold
-is set to the value of `system-cluster-critical` priority class.
-E.g.
-
-Setting `thresholdPriority`
-```yaml
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:
-        podLifeTime:
-          maxPodLifeTimeSeconds: 86400
-        thresholdPriority: 10000

-          maxPodLifeTimeSeconds: 86400
-        thresholdPriorityClassName: "priorityclass1"
-```
-
-Note that you can't configure both `thresholdPriority` and `thresholdPriorityClassName`, if the given priority class
-does not exist, descheduler won't create it and will throw an error.

 ### Notes
-It's important to create the tag on the master branch after creating the release-* branch so that the [Helm releaser-action](#helm-chart) can work.
-It compares the changes in the action-triggering branch to the latest tag on that branch, so if you tag before creating the new branch there
-will be nothing to compare and it will fail (creating a new release branch usually involves no code changes). For this same reason, you should
-also tag patch releases (on the release-* branch) *after* pushing changes (if those changes involve bumping the Helm chart version).

-### Balance Cluster By Node Memory Utilization
-
-If your cluster has been running for a long period of time, you may find that the resource utilization is not very
-balanced. The `LowNodeUtilization` strategy can be used to rebalance your cluster based on `cpu`, `memory`
-or `number of pods`.
-
-Using the following policy configuration file, descheduler will rebalance the cluster based on memory by evicting pods
-from nodes with memory utilization over 70% to nodes with memory utilization below 20%.
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "LowNodeUtilization":
-    enabled: true
-    params:

-        targetThresholds:
-          "memory": 70
-```
-
-### Autoheal Node Problems
-Descheduler's `RemovePodsViolatingNodeTaints` strategy can be combined with
-[Node Problem Detector](https://github.com/kubernetes/node-problem-detector/) and
-[Cluster Autoscaler](https://github.com/kubernetes/autoscaler/tree/master/cluster-autoscaler) to automatically remove
-Nodes which have problems. Node Problem Detector can detect specific Node problems and taint any Nodes which have those
-problems. The Descheduler will then deschedule workloads from those Nodes. Finally, if the descheduled Node's resource
-allocation falls below the Cluster Autoscaler's scale down threshold, the Node will become a scale down candidate
-and can be removed by Cluster Autoscaler. These three components form an autohealing cycle for Node problems.

-
-Package go-autorest provides an HTTP request client for use with [Autorest](https://github.com/Azure/autorest.go)-generated API client packages.
-
-An authentication client tested with Azure Active Directory (AAD) is also
-provided in this repo in the package
-`github.com/Azure/go-autorest/autorest/adal`.  Despite its name, this package
-is maintained only as part of the Azure Go SDK and is not related to other
-"ADAL" libraries in [github.com/AzureAD](https://github.com/AzureAD).
-
-## Overview
-
-Package go-autorest implements an HTTP request pipeline suitable for use across
-multiple goroutines and provides the shared routines used by packages generated
-by [Autorest](https://github.com/Azure/autorest.go).
-
-The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
-and Responding. A typical pattern is:
-
-```go
-  req, err := Prepare(&http.Request{},
-    token.WithAuthorization())
-
-  resp, err := Send(req,
-    WithLogging(logger),
-    DoErrorIfStatusCode(http.StatusInternalServerError),
-    DoCloseIfError(),
-    DoRetryForAttempts(5, time.Second))
-
-  err = Respond(resp,
-		ByDiscardingBody(),
-    ByClosing())
-```
-
-Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
-and then pass the data along, pass the data first and then modify the result, or wrap themselves
-around passing the data (such as a logger might do). Decorators run in the order provided. For
-example, the following:
-
-```go
-  req, err := Prepare(&http.Request{},
-    WithBaseURL("https://microsoft.com/"),
-    WithPath("a"),
-    WithPath("b"),
-    WithPath("c"))
-```
-
-will set the URL to:
-
-```
-  https://microsoft.com/a/b/c
-```
-
-Preparers and Responders may be shared and re-used (assuming the underlying decorators support
-sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
-shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
-all bound together by means of input / output channels.
-
-Decorators hold their passed state within a closure (such as the path components in the example
-above). Be careful to share Preparers and Responders only in a context where such held state
-applies. For example, it may not make sense to share a Preparer that applies a query string from a
-fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
-struct (e.g., `ByUnmarshallingJson`) is likely incorrect.
-
-Errors raised by autorest objects and methods will conform to the `autorest.Error` interface.
-
-See the included examples for more detail. For details on the suggested use of this package by
-generated clients, see the Client described below.
-
-## Helpers
-
-### Handling Swagger Dates
-
-The Swagger specification (https://swagger.io) that drives AutoRest
-(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
-github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure correct
-parsing and formatting.
-
-### Handling Empty Values
-
-In JSON, missing values have different semantics than empty values. This is especially true for
-services using the HTTP PATCH verb. The JSON submitted with a PATCH request generally contains
-only those values to modify. Missing values are to be left unchanged. Developers, then, require a
-means to both specify an empty value and to leave the value out of the submitted JSON.
-
-The Go JSON package (`encoding/json`) supports the `omitempty` tag. When specified, it omits
-empty values from the rendered JSON. Since Go defines default values for all base types (such as ""
-for string and 0 for int) and provides no means to mark a value as actually empty, the JSON package
-treats default values as meaning empty, omitting them from the rendered JSON. This means that, using
-the Go base types encoded through the default JSON package, it is not possible to create JSON to
-clear a value at the server.
-
-The workaround within the Go community is to use pointers to base types in lieu of base types within
-structures that map to JSON. For example, instead of a value of type `string`, the workaround uses
-`*string`. While this enables distinguishing empty values from those to be unchanged, creating
-pointers to a base type (notably constant, in-line values) requires additional variables. This, for
-example,
-
-```go
-  s := struct {
-    S *string
-  }{ S: &"foo" }
-```
-fails, while, this
-
-```go
-  v := "foo"
-  s := struct {
-    S *string
-  }{ S: &v }
-```
-succeeds.
-
-To ease using pointers, the subpackage `to` contains helpers that convert to and from pointers for
-Go base types which have Swagger analogs. It also provides a helper that converts between
-`map[string]string` and `map[string]*string`, enabling the JSON to specify that the value
-associated with a key should be cleared. With the helpers, the previous example becomes
-
-```go
-  s := struct {
-    S *string
-  }{ S: to.StringPtr("foo") }
-```
-
-## Install
-
-```bash
-go get github.com/Azure/go-autorest/autorest
-go get github.com/Azure/go-autorest/autorest/azure
-go get github.com/Azure/go-autorest/autorest/date
-go get github.com/Azure/go-autorest/autorest/to
-```
-
-### Using with Go Modules
-In [v12.0.1](https://github.com/Azure/go-autorest/pull/386), this repository introduced the following modules.
-
- autorest/adal
- autorest/azure/auth
- autorest/azure/cli
- autorest/date
- autorest/mocks
- autorest/to
- autorest/validation
- autorest
- logger
- tracing
-
-Tagging cumulative SDK releases as a whole (e.g. `v12.3.0`) is still enabled to support consumers of this repo that have not yet migrated to modules.
