+[![GitHub Workflow Status](https://img.shields.io/github/workflow/status/MethodGrab/create-elm-package/CI?style=flat-square)](https://github.com/MethodGrab/create-elm-package/actions/workflows/CI.yaml)
+[![npm version](https://img.shields.io/npm/v/create-elm-package?style=flat-square)](https://www.npmjs.com/package/create-elm-package)
+
+> An [npm initializer](https://docs.npmjs.com/cli/commands/npm-init) for creating new [Elm](https://elm-lang.org) packages.
+
+
+## Usage
+
+```
+mkdir my-elm-package
+cd my-elm-package
+npm init elm-package
+```
+
+
+## What's included
+
+Please review the generated code before using it to ensure it meets your needs and doesn't include anything you don't want.
+
+- Basic Elm package boilerplate.
+- GitHub [Workflow actions](./templates/base/.github/workflows/CI.yaml) to:
+	- Validate the package.
+	- Automatically publish new versions using [`elm-publish-action`](https://github.com/dillonkearns/elm-publish-action).  
+		Note the initial version 1.0.0 must be published manually.
+
+Note the GitHub workflow assumes your default branch is called `main`. If that's not the case, you can update the 2 references to `main` at the top of `.github/workflows/CI.yaml` after you run the initializer.
+
+
+## Development
+
+1. Clone the repo.
+1. `cd create-elm-package`
+1. `npm install`
+1. `npm run dev`
+
+In a separate session/tab/window:
+1. `npm link`
+1. `npm init elm-package`  
+	This will run the local cloned/linked version.
+
+Instead of running `npm init elm-package` you can run the `create-elm-package` global binary directly.
+
+Instead of linking it with `npm link` and using the global binary you can run the local binary directly: `./dist/cli.js`.
