+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+# Kubernetes "kubectl" Provider 
+
+![Build Status](https://github.com/gavinbunney/terraform-provider-kubectl/actions/workflows/build.yml/badge.svg) [![user guide](https://img.shields.io/badge/-user%20guide-blue)](https://registry.terraform.io/providers/gavinbunney/kubectl)
+
+This provider is the best way of managing Kubernetes resources in Terraform, by allowing you to use the thing 
+Kubernetes loves best - yaml!
+
+This core of this provider is the `kubectl_manifest` resource, allowing free-form yaml to be processed and applied against Kubernetes.
+This yaml object is then tracked and handles creation, updates and deleted seamlessly - including drift detection!
+
+A set of helpful data resources to process directories of yaml files and inline templating is available.
+
+This `terraform-provider-kubectl` provider has been used by many large Kubernetes installations to completely
+manage the lifecycle of Kubernetes resources. 
+
+## Installation
+
+### Terraform 0.13+
+
+The provider can be installed and managed automatically by Terraform. Sample `versions.tf` file :
+
+```hcl
+terraform {
+  required_version = ">= 0.13"
+
+  required_providers {
+    kubectl = {
+      source  = "gavinbunney/kubectl"
+      version = ">= 1.7.0"
+    }
+  }
+}
+```
+
+### Terraform 0.12
+
+#### Install latest version
+
+The following one-liner script will fetch the latest provider version and download it to your `~/.terraform.d/plugins` directory.
+
+```bash
+$ mkdir -p ~/.terraform.d/plugins && \
+      curl -Ls https://api.github.com/repos/gavinbunney/terraform-provider-kubectl/releases/latest \
+      | jq -r ".assets[] | select(.browser_download_url | contains(\"$(uname -s | tr A-Z a-z)\")) | select(.browser_download_url | contains(\"amd64\")) | .browser_download_url" \
+      | xargs -n 1 curl -Lo ~/.terraform.d/plugins/terraform-provider-kubectl.zip && \
+      pushd ~/.terraform.d/plugins/ && \
+      unzip ~/.terraform.d/plugins/terraform-provider-kubectl.zip -d terraform-provider-kubectl-tmp && \
+      mv terraform-provider-kubectl-tmp/terraform-provider-kubectl* . && \
+      chmod +x terraform-provider-kubectl* && \
+      rm -rf terraform-provider-kubectl-tmp && \
+      rm -rf terraform-provider-kubectl.zip && \
+      popd
+```
+
+#### Install manually
+
+If you don't want to use the one-liner above, you can download a binary for your system from the [release page](https://github.com/gavinbunney/terraform-provider-kubectl/releases), 
+then either place it at the root of your Terraform folder or in the Terraform plugin folder on your system.
+
+## Quick Start
+
+```hcl
+provider "kubectl" {
+  host                   = var.eks_cluster_endpoint
+  cluster_ca_certificate = base64decode(var.eks_cluster_ca)
+  token                  = data.aws_eks_cluster_auth.main.token
+  load_config_file       = false
+}
+
+resource "kubectl_manifest" "test" {
+    yaml_body = <<YAML
+apiVersion: couchbase.com/v1
+kind: CouchbaseCluster
+metadata:
+  name: name-here-cluster
+spec:
+  baseImage: name-here-image

+YAML
+}
+```
+
+See [User Guide](https://registry.terraform.io/providers/gavinbunney/kubectl/latest) for details on installation and all the provided data and resource types.
+
+---
+
+## Development Guide
+
+If you wish to work on the provider, you'll first need [Go](http://www.golang.org) installed on your machine (version 1.12+ is *required*).
+You'll also need to correctly setup a [GOPATH](http://golang.org/doc/code.html#GOPATH), as well as adding `$GOPATH/bin` to your `$PATH`.
+
+To compile the provider, run `make build`. This will build the provider and put the provider binary in the `$GOPATH/bin` directory.
+
+### Building The Provider
+
+```sh
+$ go get github.com/gavinbunney/terraform-provider-kubectl
+```
+
+Enter the provider directory and build the provider
+
+```sh
+$ cd $GOPATH/src/github.com/gavinbunney/terraform-provider-kubectl
+$ make build
+```
+
+### Testing
+
+In order to test the provider, you can simply run `make test`.
+
+```sh
+$ make test
+```
+
+The provider uses k3s to run integration tests. These tests look for any `*.tf` files in the `_examples` folder and run an `plan`, `apply`, `refresh` and `plan` loop over each file. 
+
+Inside each file the string `name-here` is replaced with a unique name during test execution. This is a simple string replace before the TF is applied to ensure that tests don't fail due to naming clashes. 
+
+Each scenario can be placed in a folder, to help others navigate and use the examples, and added to the [README.MD](./_examples/README.MD). 
+
+> Note: The test infrastructure doesn't support multi-file TF configurations so ensure your test scenario is in a single file. 
+
+In order to run the full suite of Acceptance tests, run `make testacc`.
+
+*Note:* Acceptance tests create real resources, and often cost money to run.
+
+```sh
+$ make testacc
+```
+
+### Inspiration
