-**Warning:** The acceptance tests create/destroy/modify _real resources_, which
-may incur costs for real money. In the presence of a bug, it is possible that
-resources may be left behind, which can cost money even though you were not
-using them. We recommend running tests in an account used only for that purpose
-so it is easy to see if there are any dangling resources, and so production
-resources are not accidentally destroyed or overwritten during testing.
-Also, these typically require an API key (AWS, GCE), or additional software
-to be installed on your computer (VirtualBox, VMware).
-
-To run the Provisioners Acceptance Tests you should use the
-**ACC_TEST_BUILDERS** environment variable to tell the tests which builder the
-test should be run against.

-The **ACC_TEST_BUILDERS** env variable accepts a list of builders separated by
-commas. (e.g. `ACC_TEST_BUILDERS=amazon-ebs,virtualbox-iso`)
-
-
-#### Writing Provisioner Acceptance Tests
-
-Packer has implemented a `ProvisionerTestCase` structure to help write
-provisioner acceptance tests.
-
-```go
-type ProvisionerTestCase struct {
-  // Check is called after this step is executed in order to test that
-  // the step executed successfully. If this is not set, then the next
-  // step will be called
-  Check func(*exec.Cmd, string) error
-  // IsCompatible checks whether a provisioner is able to run against a
-  // given builder type and guest operating system, and returns a boolean.
-  // if it returns true, the test combination is okay to run. If false, the
-  // test combination is not okay to run.
-  IsCompatible func(builderType string, BuilderGuestOS string) bool
-  // Name is the name of the test case. Be simple but unique and descriptive.
-  Name string
-  // Setup, if non-nil, will be called once before the test case
-  // runs. This can be used for some setup like setting environment
-  // variables, or for validation prior to the
-  // test running. For example, you can use this to make sure certain
-  // binaries are installed, or text fixtures are in place.
-  Setup func() error
-  // Teardown will be called before the test case is over regardless
-  // of if the test succeeded or failed. This should return an error
-  // in the case that the test can't guarantee all resources were
-  // properly cleaned up.
-  Teardown builderT.TestTeardownFunc
-  // Template is the provisioner template to use.
-  // The provisioner template fragment must be a json-formatted string
-  // containing the provisioner definition but no other portions of a packer
-  // template. For
-  // example:
-  //
-  // ```json
-  // {
-  //  "type": "shell-local",
-  //  "inline", ["echo hello world"]
-  // }
-  //```
-  //
-  // is a valid entry for "template" here, but the complete Packer template:
-  //
-  // ```json
-  // {
-  //  "provisioners": [
-  //    {
-  //      "type": "shell-local",
-  //      "inline", ["echo hello world"]
-  //    }
-  //  ]
-  // }
-  // ```
-  //
-  // is invalid as input.
-  //
-  // You may provide multiple provisioners in the same template. For example:
-  // ```json
-  // {
-  //  "type": "shell-local",
-  //  "inline", ["echo hello world"]
-  // },
-  // {
-  //  "type": "shell-local",
-  //  "inline", ["echo hello world 2"]
-  // }
-  // ```
-  Template string
-  // Type is the type of provisioner.
-  Type string
-}
-
-```
-
-To start writing a new provisioner acceptance test, you should add a test file
-named `provisioner_acc_test.go` in the same folder as your provisioner is
-defined. Create a test case by implementing the above struct, and run it
-by calling `provisioneracc.TestProvisionersAgainstBuilders(testCase, t)`
-
-The following example has been adapted from a shell-local provisioner test:
-
-```
-import (
-  "github.com/hashicorp/packer-plugin-sdk/acctest/provisioneracc"
-  "github.com/hashicorp/packer-plugin-sdk/acctest/testutils"
-)
-
-// ...
-
-func TestAccShellProvisioner_basic(t *testing.T) {
-  // Create a json template fragment containing just the provisioners you want
-  // to run.
-  templateString := `{
-    "type": "shell-local",
-    "script": "test-fixtures/script.sh",
-    "max_retries" : 5
-}`
-
-  // instantiate a test case.
-  testCase := &provisioneracc.ProvisionerTestCase{
-    IsCompatible: func() bool {return true},
-    Name:         "shell-local-provisioner-basic",
-    Teardown: func() error {
-      testutils.CleanupFiles("test-fixtures/file.txt")
-      return nil
-    },
-    Template: templateString,
-    Type:     "shell-local",
-    Check: func(buildcommand *exec.Cmd, logfile string) error {
-      if buildcommand.ProcessState != nil {
-        if buildcommand.ProcessState.ExitCode() != 0 {
-          return fmt.Errorf("Bad exit code. Logfile: %s", logfile)
-        }
-      }
-      filecontents, err := loadFile("file.txt")
-      if err != nil {
-        return err
-      }
-      if !strings.Contains(filecontents, "hello") {
-        return fmt.Errorf("file contents were wrong: %s", filecontents)
-      }
-      return nil
-    },
-  }
-
-  provisioneracc.TestProvisionersAgainstBuilders(testCase, t)
-}
-
-```
-
-
-After writing the struct and implementing the interface, now is time to write the test that will run all
-of this code you wrote. Your test should be like:
-
-```go
-func TestShellProvisioner(t *testing.T) {
-	acc.TestProvisionersPreCheck("shell", t)
-	acc.TestProvisionersAgainstBuilders(new(ShellProvisionerAccTest), t)
-}
-```
-
-The method `TestProvisionersAgainstBuilders` will run the provisioner against
-all available and compatible builders. If there are not builders compatible with
-the test you want to run, you can add a builder using the following steps:
-
-Create a subdirectory in provisioneracc/test-fixtures for the type of builder
-you are adding. In this subdirectory, add one json file containing a single
-builder fragment. For example, one of our amazon-ebs builders is defined in
-provisioneracc/test-fixtures/amazon-ebs/amazon-ebs.txt and contains:
-
-```json
-{
-  "type": "amazon-ebs",
-  "ami_name": "packer-acc-test",
-  "instance_type": "t2.micro",
-  "region": "us-east-1",
-  "ssh_username": "ubuntu",
-  "source_ami_filter": {
-    "filters": {
-      "virtualization-type": "hvm",
-      "name": "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*",
-      "root-device-type": "ebs"
-    },
-    "owners": ["099720109477"],
-    "most_recent": true
-  },
-  "force_deregister" : true,
-  "tags": {
-    "packer-test": "true"
-  }
-}
-```
-
-note that this fragment does not contain anything other than a single builder
-definition. The testing framework will combine this with the provisioner
-fragment to create a working json template.
-
-In order to tell the testing framework how to use this builder fragment, you
-need to implement a `BuilderFixture` struct:
-
-```go
-type BuilderFixture struct {
-  // Name is the name of the builder fixture.
-  // Be simple and descriptive.
-  Name string
-  // Setup creates necessary extra test fixtures, and renders their values
-  // into the BuilderFixture.Template.
-  Setup func()
-  // Template is the path to a builder template fragment.
-  // The builder template fragment must be a json-formatted file containing
-  // the builder definition but no other portions of a packer template. For
-  // example:
-  //
-  // ```json
-  // {
-  //  "type": "null",
-  //  "communicator", "none"
-  // }
-  //```
-  //
-  // is a valid entry for "template" here, but the complete Packer template:
-  //
-  // ```json
-  // {
-  //  "builders": [
-  //    "type": "null",
-  //    "communicator": "none"
-  //  ]
-  // }
-  // ```
-  //
-  // is invalid as input.
-  //
-  // Only provide one builder template fragment per file.
-  TemplatePath string
-
-  // GuestOS says what guest os type the builder template fragment creates.
-  // Valid values are "windows", "linux" or "darwin" guests.
-  GuestOS string
-
-  // HostOS says what host os type the builder is capable of running on.
-  // Valid values are "any", windows", or "posix". If you set "posix", then
-  // this builder can run on a "linux" or "darwin" platform. If you set
-  // "any", then this builder can be used on any platform.
-  HostOS string
-
-  Teardown builderT.TestTeardownFunc
-}
-```
-Implement this struct to the file "provisioneracc/builders.go", then add
-the new implementation to the `BuildersAccTest` map in
-`provisioneracc/provisioners.go`
-
-Once you finish these steps, you should be ready to run your new provisioner
-acceptance test by setting the name used in the BuildersAccTest map as your
-`ACC_TEST_BUILDERS` environment variable.

+## Developing Packer
 
 See
 [CONTRIBUTING.md](https://github.com/hashicorp/packer/blob/master/.github/CONTRIBUTING.md)
 for best practices and instructions on setting up your development environment

-## Unmaintained Plugins
-As contributors' circumstances change, development on a community maintained
-plugin can slow. When this happens, the Packer team may mark a plugin as
-unmaintained, to clearly signal the plugin's status to users.
-
-What does **unmaintained** mean?
-
-1. The code repository and all commit history will still be available.
-1. Documentation will remain on the Packer website.
-1. Issues and pull requests are monitored as a best effort.
-1. No active development will be performed by the Packer team.
-
-If anyone form them community is interested in maintaining a community
-supported plugin, please feel free to submit contributions via a pull-
-request for review; reviews are generally prioritized over feature work
-when possible. For a list of open plugin issues and pending feature requests see the [Packer Issue Tracker](https://github.com/hashicorp/packer/issues/).
