-## Running a local version of Hydrogen in a Hydrogen app
-
-> Caution:
-> You must use `yarn` for all commands, due to issues with NPM and dependencies, even if the prompt tells you to use `npm`.
-
-Follow these instructions to create your own Hydrogen app using the local development version of the Hydrogen framework.
-
-Before running any commands, be sure to build the Hydrogen lib with `yarn dev-lib` or `yarn build`.
-
-```bash
-cd packages/create-hydrogen-app && yarn link
-```
-
-This makes the executable `create-hydrogen` available globally.
-
-Next, choose an option below.
-
-### Option 1: `localdev` package
-
-This option creates a new Hydrogen app similar to `templates/demo-store` directly in the monorepo under `packages/localdev`. This directory is ignored in git, so your changes will not be tracked.
-
-```terminal
-create-hydrogen packages/localdev
-# when prompted, use `localdev` for the package name
-```
-
-Then run your app:
-
-```terminal
-yarn workspace localdev dev
-```
-
-### Option 2: Standalone package
-
-> Caution:
-> This requires you to have a directory structure on your machine like `~/src/github.com/Shopify/*`, and it requires you to create your custom Hydrogen app in a namespace similar to `~/src/github.com/<namespace>/<your hydrogen app here>`.
-
-1. In the directory you want to create your Hydrogen app, run `LOCAL=true create-hydrogen` and answer the prompts.
-1. Run `cd <your app>`.
-1. Run `yarn` or `npm i`.
-1. Optional. Replace default `hydrogen.config.js` with your own storefront credentials.
-1. Run `yarn dev` or `npm run dev` to start your dev server.
-1. Open the dev server in your browser at http://localhost:3000.
-
-If you make changes to core Hydrogen packages, then you'll need to delete `node_modules`, install dependencies again and start the server as mentioned above.

 ## Testing
 
 Hydrogen is tested with unit tests for components, hooks and utilities. It is also tested with a suite of end-to-end tests inspired by [Vite's playground tests](https://github.com/vitejs/vite/tree/main/packages/playground).

 **After merging the auto-generated changeset PR, my GitHub Action encountered an Error with the message `No commits between X and changeset-release/Y`**
 
 This happens when changesets does not properly clear out all the changesets in the `.changesets` directory of the hydrogen repo. The soluction is to create a new PR with all of the `.changesets` removed. The GitHub Action will re-run when you merge the second PR.

-## Things to consider and improve upon
-
-- Oxygen reads the hydrogen `demo-store` template from the `create-hydrogen-app` package in this repo. Until the Oxygen teams updates their workflow, we need to continue to publish this package whenever the `demo-store` template changes.
