+## Contributor Ladder
+
+Kustomize generally follows the [Kubernetes Community Membership](https://github.com/kubernetes/community/blob/master/community-membership.md) contributor ladder. Roles are as follows:
+
+1. Contributor: Anyone who actively contributes code, issues or reviews to the project. There are no Kustomize-specific requirements for this status. All contributors must [sign the CLA](https://github.com/kubernetes/community/tree/master/contributors/guide#prerequisites).
+1. Member/Reviewer: All Kubernetes-SIGs org members have LGTM rights on the Kustomize repo. There are no Kustomize-specific requirements. Kustomize does not currently have any formal reviewers, but the role will be created if there is interest.
+1. Maintainer/Approver: Highly experienced active reviewer and contributor to Kustomize. Has both LTGM and approval rights on the Kustomize repo, as well as [Github "maintain" rights](https://docs.github.com/en/organizations/managing-access-to-your-organizations-repositories/repository-permission-levels-for-an-organization#repository-access-for-each-permission-level).
+1. Admin/Owner: Maintainer who sets technical direction and makes or approves design decisions for the project. Has LGTM and approval rights on the Kustomize repo as well as [Github "admin" rights](https://docs.github.com/en/organizations/managing-access-to-your-organizations-repositories/repository-permission-levels-for-an-organization#repository-access-for-each-permission-level).
+
+Administrative notes:
+- Maintainers and admins must be added to the appropriate list both [in the Kustomize repo](https://github.com/kubernetes-sigs/kustomize/blob/8049f7b1af52e8a7ec26faf6cf714f560d0043c5/OWNERS_ALIASES) and [in the community repo](https://github.com/kubernetes/org/blob/main/config/kubernetes-sigs/sig-cli/teams.yaml). If this isn't done, the individual in question will lack either PR approval rights (Kustomize list) or the appropriate Github repository permissions (community list).
+- The spec for the OWNERS file is [in the community repo](https://github.com/kubernetes/community/blob/master/contributors/guide/owners.md).

-
-Resource Configuration may be read / written from / to sources such as directories,
-stdin|out or network. Tools may be composed using pipes such that the tools writing
-Resource Configuration may be a different tool from the one that read the configuration.
-In order for tools to be composed in this way, while preserving origin information --
-such as the original file, index, etc.:
-
-Tools **SHOULD** insert the following annotations when reading from sources,
-and **SHOULD** delete the annotations when writing to sinks.
-
-### `config.kubernetes.io/path`
-
-Records the slash-delimited, OS-agnostic, relative file path to a Resource.
-
-This annotation **SHOULD** be set when reading Resources from files.
-It **SHOULD** be unset when writing Resources to files.
-When writing Resources to a directory, the Resource **SHOULD** be written to the corresponding
-path relative to that directory.
-
-Example:
-
-```yaml
-metadata:
-  annotations:
-    config.kubernetes.io/path: "relative/file/path.yaml"
-```
-
-### `config.kubernetes.io/index`
-
-Records the index of a Resource in file. In a multi-object YAML file, Resources are separated
-by three dashes (`---`), and the index represents the position of the Resource starting from zero.
-
-This annotation **SHOULD** be set when reading Resources from files.
-It **SHOULD** be unset when writing Resources to files.
-When writing multiple Resources to the same file, the Resource **SHOULD** be written in the

-
-### `config.kubernetes.io/local-config`
-
-`config.kubernetes.io/local-config` declares that the configuration is to local tools
-rather than a remote Resource. e.g. The `Kustomization` config in a `kustomization.yaml`

-## Spec
+## Definitions
 
-### Input Type
+- **function:** A containerized program conforming to the spec described in this
+  document.
+- **orchestrator:** A program that invokes the function container, passing
+  arguments and processing its output.
 
-A function MUST accept as input a single [Kubernetes List type][3].
-The `items` field in the input will contain a sequence of [Object types][3].
-A function MAY not support [Simple types][3] and List types.
+## Interface
 
-An example using `v1/ConfigMapList` as input:
+The inter-process communication between the orchestrator and a function works as
+follows:
+
+1. Orchestrator runs the function container and provides the input on `stdin`.
+   The input is a Kubernetes object of kind `ResourceList` as described below.
+2. Function reads the input from `stdin`, performs computations, and provides
+   the output as a `ResourceList` to `stdout`. The function MAY also emit
+   non-structured error message on `stderr`.
+3. Orchestrator uses the `stdout`, `stderr`, and the exit code of the function
+   as it sees fit following to the semantics described below.
+
+### Schema
+
+A function MUST accept input from `stdin` and MUST output to `stdout` a
+Kubernetes object of kind `ResourceList` with the following OpenAPI schema:

-An example using `v1/List` as input:
+#### Examples
+
+The following is an example input, where the custom resource of kind
+`FulfillmentCenter` is provided as `functionConfig`. The function will operate
+on one resource of kind `Service`.
 
 ```yaml
-apiVersion: v1
-kind: List
-items:
-  - apiVersion: foo-corp.com/v1
-    kind: FulfillmentCenter
-    metadata:
-      name: staging
-    address: "100 Main St."
-  - apiVersion: rbac.authorization.k8s.io/v1
-    kind: ClusterRole
-    metadata:
-      name: namespace-reader
-    rules:
-      - resources:
-          - namespaces
-        apiGroups:

-        verbs:
-          - get
-          - watch
-          - list
-```
-
-In addition, a function MUST accept as input a List of kind `ResourceList` where the
-`functionConfig` field, if present, will contain the invocation-specific configuration passed to the function
-by the orchestrator.
-Functions MAY consider this field optional so that they can be triggered in an ad-hoc fashion.

 ### Serialization Format
 
 A function MUST support YAML as a serialization format for the input and output.
-A function MUST use utf8 encoding (as YAML is a superset of JSON, JSON will also be supported
-by any conforming function).
-
-### Operations
-
-A function MAY Create, Update, or Delete any number of items in the `items` field and output the
-resultant list.
-
-A function MAY modify annotations with prefix `config.kubernetes.io`, but must be careful about
-doing so since they’re used for orchestration purposes and will likely impact subsequent functions
-in the pipeline.
-
-A function SHOULD preserve comments when input serialization format is YAML.
-This allows for human authoring of configuration to coexist with changes made by functions.

 ### Containerization
 
 A function MUST be implemented as a container.
 
-A function container MUST be capable of running as a non-root user if it does not require
-access to host filesystem or makes network calls.
+A function container MUST be capable of running as a non-root user `nobody` if

-A function MUST accept input from stdin and emit output to stdout.
+Any non-structured error messages MUST be emitted to `stderr`. `stdout` is
+reserved for `ResourceList` as described above.
 
-Any error messages MUST be emitted to stderr.
+### Exit Code
 
-An exit code of zero indicates function execution was successful.
-A non-zero exit code indicates a failure.

+
+A function MAY Create, Update, or Delete any number of items in the `items`
+field and output the resultant list in the corresponding `items` field of the
+output.
+
+A function SHOULD preserve comments when input serialization format is YAML.
+This allows for human authoring of configuration to coexist with changes made by
+functions.
+
+### Annotations
+
+The orchestrator annotates resources in the wire format with annotation prefix
+`config.kubernetes.io`. These annotations are not persisted when the
+orchestrator writes the resources to the filesystem. The orchestrator sets this
+annotation when reading files from the local filesystem and removes the
+annotation when writing the output of functions back to the filesystem.
+
+In general, a function MUST NOT modify these annotations except the ones
+explicitly listed below.
+
+#### `config.kubernetes.io/path`
+
+Records the slash-delimited, OS-agnostic, relative file path to a resource. The
+path is relative to a fix location on the filesystem. Different orchestrator
+implementations can choose different fixed points.
+
+A function SHOULD NOT modify this annotation.
+
+Example:
+
+```yaml
+metadata:
+  annotations:
+    config.kubernetes.io/path: "relative/file/path.yaml"
+```
+
+#### `config.kubernetes.io/index`
+
+Records the index of a Resource in file. In a multi-object YAML file, resources
+are separated by three dashes (`---`), and the index represents the position of
+the Resource starting from zero. When this annotation is not specified, it
+implies a value of `0`.
+
+A function SHOULD NOT modify this annotation.
+
+Example:
+
+```yaml
+metadata:
+  annotations:
+    config.kubernetes.io/path: "relative/file/path.yaml"
+    config.kubernetes.io/index: 2
+```
+
+This represents the third resource in the file.
