-  The command line tools to interact with Kustomize.
----
+  Reference for the Command Line Interface.
+---
+
+This overview covers `kustomize` syntax, describes the command operations, and provides common examples.
+
+## Syntax
+Use the following syntax to run `kustomize` commands from your terminal window:
+
+```bash
+kustomize [command]
+```
+
+The `command` flag specifies the operation that you want to perform, for example `create`, `build`, `cfg`.
+
+If you need help, run `kustomize help` from the terminal window.
+
+## Operations
+The following table includes short descriptions and the general syntax for all the `kustomize` operations.
+
+Operation | Syntax | Description
+--- | --- | ---
+build | `kustomize build DIR [flags]` | Build a kustomization target from a directory or URL.
+cfg | `kustomize cfg [command]` | Commands for reading and writing configuration.
+completion | `kustomize completion` [bash\|zsh\|fish\|powershell] | Generate shell completion script.
+create | `kustomize create [flags]` | Create a new kustomization in the current directory.
+edit | `kustomize edit [command]` |  Edits a kustomization file.
+fn | `kustomize fn [command]` | Commands for running functions against configuration.
+localize | `kustomize localize [target [destination]] [flags]` | [Alpha] Creates localized copy of target kustomization root at destination.
+version | `kustomize version [flags]` | Prints the kustomize version.
+
+## Examples: Common Operations
+Use the following set of examples to help you familiarize yourself with running the commonly used `kustomize` operations:
+
+`kustomize build` - Build a kustomization target from a directory or URL.
+
+```bash
+# Build the current working directory
+kustomize build
+
+# Build some shared configuration directory
+kustomize build /home/config/production
+
+# Build from github
+kustomize build https://github.com/kubernetes-sigs/kustomize.git/examples/helloWorld?ref=v1.0.6
+```
+
+`kustomize create` - Create a new kustomization in the current directory.
+```bash
+# Create an empty kustomization.yaml file
+kustomize create
+
+# Create a new overlay from the base '../base".
+kustomize create --resources ../base
+
+# Create a new kustomization detecting resources in the current directory.
+kustomize create --autodetect
+
+# Create a new kustomization with multiple resources and fields set.
+kustomize create --resources deployment.yaml,service.yaml,../base --namespace staging --nameprefix acme-
+```
+
+`kustomize edit` - Edits a kustomization file.
+```bash
+# Adds a configmap to the kustomization file
+kustomize edit add configmap NAME --from-literal=k=v
+
+# Sets the nameprefix field
+kustomize edit set nameprefix <prefix-value>
+
+# Sets the namesuffix field
+kustomize edit set namesuffix <suffix-value>
+```
