-Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/main/packages/create-svelte).
+This is a Sveltekit project that is deployed to GH pages.
 
-## Creating a project
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```bash
-# create a new project in the current directory
-npm create svelte@latest
-
-# create a new project in my-app
-npm create svelte@latest my-app
-```
-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+To use it to test-drive changes in the package itself, link to the built project:
 
 ```bash
-npm run dev
-
-# or start the server and open the app in a new browser tab
-npm run dev -- --open
+# In the workspace folder (not this, the pages/ folder):
+npm run build && npm link
 ```
 
-## Building
-
-To create a production version of your app:
+Now complete the link:
 
 ```bash
-npm run build
+# In the pages/ folder:
+npm link @wjfe/async-workers
 ```
 
-You can preview the production build with `npm run preview`.
-
-> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.
+If you're not working on the package itself, you may install `@wjfe/async-workers`.
