 ## Development
 
-This repository contains the source for the unpkg.com production server. The source is divided into two [Cloudflare Workers](https://workers.cloudflare.com/):
+This repository contains the production source for UNPKG. There are 4 packages:
 
-- [`unpkg-www-worker`](./workers/www/) serves all files on npm and the main homepage
-- [`unpkg-app-worker`](./workers/app/) serves the package detail pages
+- [`unpkg-app`](./packages/unpkg-app/) is the UNPKG web app (file browser)
+- [`unpkg-files`](./packages/unpkg-files/) is the file server backend that fetches tarballs from npm and extracts their contents
+- [`unpkg-worker`](./packages/unpkg-worker/) is a shared set of utilites between the web apps (Cloudflare workers)
+- [`unpkg-www`](./packages/unpkg-www/) is the main UNPKG app
 
-To run everything locally, you'll first need to do an install:
+We use [Bun](https://bun.sh/) in development, as well as [pnpm](https://pnpm.io/). Install these first.
+
+Next, install all dependencies and run the tests:
 
 ```sh
 pnpm install
+pnpm test
 ```
 
-Then start each worker along with its assets server (you'll need 4 terminal tabs):
+Then start the file server and each worker along with its assets server (you'll need 5 terminal tabs):
 
 ```sh
-cd workers/www && pnpm dev

-The dev server will be listening on `http://localhost:3000`. [Wrangler](https://developers.cloudflare.com/workers/cli-wrangler) allows the workers to find and communicate with each other in dev.
+The dev server will be listening on `http://localhost:3000`.
 
 ## Deploying
 
-To deploy the workers, you'll need to have a [Cloudflare](https://cloudflare.com) account. You will also need to edit the `wrangler.json` file in each worker and update its [`routes`](https://developers.cloudflare.com/workers/wrangler/configuration/) to your own domain(s). You'll also need to adjust each worker's environment `vars` (in `wrangler.json`) so they can find one another in production.
+The `unpkg-files` backend is deployed on [Fly.io](https://fly.io). You'll need an account.
+
+Next, adjust the Fly config in `packages/unpkg-files/fly.json` (you'll need your own app `name`) and deploy:
+
+```sh
+cd packages/unpkg-files && pnpm run deploy
+```
+
+To deploy the workers, you'll need a [Cloudflare](https://cloudflare.com) account. You will also need to (1) edit the `wrangler.json` file in each worker and update its [`routes`](https://developers.cloudflare.com/workers/wrangler/configuration/) to your own domain(s) and (2) adjust each worker's environment `vars` (in `wrangler.json`) so they can find one another in production.
 
 Once you've done that, you can deploy each worker with:
 
 ```sh
-cd workers/www && pnpm run deploy
-cd workers/app && pnpm run deploy
+cd packages/unpkg-www && pnpm run deploy
+cd packages/unpkg-app && pnpm run deploy

+# unpkg-files
+
+This package is the file server for UNPKG. It has one job: fetch tarballs from npm, decompress them, and extract their contents. It is deployed on [Fly.io](https://fly.io/).
+
+## Development
+
+Install dependencies and run the tests:
+
+```
+pnpm install
+pnpm test
+```
+
+Boot the dev server:
+
+```
+pnpm dev
+```
+
+## Deploying
+
+Build the server and boot it:
+
+```
+pnpm build
+bun ./dist/server.js
+```

+## Development
+
+Install dependencies and run the tests:
+
+```
+pnpm install
+pnpm test
+```
+
+Boot the dev server and assets server (two separate tabs):
+
+```
+pnpm dev
+pnpm dev:assets
+```
+
+## Deploying
+
+Edit the worker configuration in `wrangler.json`, then:
+
+```
+pnpm run deploy
