-**The good starter example for using [Marp] via [Marp CLI].**
-
-- Write your slide deck by [Marp] Markdown.
-- Manage the content of slides via Git. (Using [GitPitch](https://github.com/gitpitch/gitpitch) style `PITCHME.md`)
-- Host your deck at GitHub, and publish as webpage with [GitHub Pages], [Netlify], and [Vercel].
-- Blazingly fast delivery out of the box. [Acquired all 100% Lighthouse scores!](#lighthouse)

-## Usage
-
-It's surprisingly easy to start publishing your slide deck!
-
-### [GitHub Pages]
-
-Create a new _public_ repository based on this repository, from **"Use this template"** button!
-
-[](https://github.com/yhatt/marp-cli-example/generate)
-
-We already have [GitHub Actions workflow](.github/workflows/github-pages.yml) to build and deploy automatically when merged to master branch. It's also available to deploy from any branch manually.
-
-To get started, turn on GitHub Pages in repository's "**Settings** tab → **Pages**" [by setting source as "GitHub Actions"](https://docs.github.com/en/pages/getting-started-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site#publishing-with-a-custom-github-actions-workflow).
-
-### [Netlify]
-
-Push **"Deploy to netlify"** button. [Netlify] will create your repository based on this example and host website from `master` branch automatically.
-
-[](https://app.netlify.com/start/deploy?repository=https://github.com/yhatt/marp-cli-example)
-
-### [Vercel]
-
-Push **"Deploy"** button. [Vercel] can choose to create your repository based on this example.
-
-[](https://vercel.com/import/project?template=https://github.com/yhatt/marp-cli-example)
-
-> :information_source: To enable the auto-generated open graph image in Vercel, you have to turn on ["Automatically expose System Environment Variables"](https://vercel.com/docs/concepts/projects/environment-variables#system-environment-variables) in your Vercel project dashboard.
-
-## How to write
-
-For Marp slide deck features, please see the documentation of [Marpit Markdown](https://marpit.marp.app/markdown), [the features of Marp Core](https://github.com/marp-team/marp-core#features), and the default example in [`PITCHME.md`](https://raw.githubusercontent.com/yhatt/marp-cli-example/master/PITCHME.md) for .
-
-You have to install [Node.js](https://nodejs.org/) and run `npm i` at first if you want to write slide deck with [Marp CLI].
-
-### Edit deck
-
-Just edit **[`PITCHME.md`](./PITCHME.md)**!
-
-#### Preview deck
-
-**[Marp for VS Code]** extension is the best partner for writing Marp slide deck with live preview.
-
-
-
-**You can try edit and preview on the web now!** Open https://github.dev/yhatt/marp-cli-example/blob/master/PITCHME.md or hit . key on this repository, and install [Marp for VS Code] extension.
