@@ -33,125 +33,15 @@ bun run clean    # Remove dist/
 - Uses `Bun.serve()` to serve static files from `dist/`
 - Watches `proposals/` and `styles.css` for changes
 - SSE endpoint at `/__reload` for live reload
-- Live reload script only injected in dev mode
 
 ## Styling
 
 - CSS custom properties for theming (`--bg`, `--fg`, `--link`, etc.)
 - System preference detection via `prefers-color-scheme`
-- Three-state toggle: auto → dark → light → auto
+- Two-state toggle: dark ↔ light
 - Theme persisted to localStorage
 
 ## Adding Features
 
 - Keep dependencies minimal (only `@types/bun` currently)
 - Use Bun built-ins: `Bun.file`, `Bun.Glob`, `Bun.markdown`, `Bun.serve`
-- Maintain the retro monospace aesthetic
-
----
-
-Default to using Bun instead of Node.js.
-
-- Use `bun <file>` instead of `node <file>` or `ts-node <file>`
-- Use `bun test` instead of `jest` or `vitest`
-- Use `bun build <file.html|file.ts|file.css>` instead of `webpack` or `esbuild`
-- Use `bun install` instead of `npm install` or `yarn install` or `pnpm install`
-- Use `bun run <script>` instead of `npm run <script>` or `yarn run <script>` or `pnpm run <script>`
-- Use `bunx <package> <command>` instead of `npx <package> <command>`
-- Bun automatically loads .env, so don't use dotenv.
-
-## APIs
-
-- `Bun.serve()` supports WebSockets, HTTPS, and routes. Don't use `express`.
-- `bun:sqlite` for SQLite. Don't use `better-sqlite3`.
-- `Bun.redis` for Redis. Don't use `ioredis`.
-- `Bun.sql` for Postgres. Don't use `pg` or `postgres.js`.
-- `WebSocket` is built-in. Don't use `ws`.
-- Prefer `Bun.file` over `node:fs`'s readFile/writeFile
-- Bun.$`ls` instead of execa.
-
-## Testing
-
-Use `bun test` to run tests.
-
-```ts#index.test.ts
-import { test, expect } from "bun:test";
-
-test("hello world", () => {
-  expect(1).toBe(1);
-});
-```
-
-## Frontend
-
-Use HTML imports with `Bun.serve()`. Don't use `vite`. HTML imports fully support React, CSS, Tailwind.
-
-Server:
-
-```ts#index.ts
-import index from "./index.html"
-
-Bun.serve({
-  routes: {
-    "/": index,
-    "/api/users/:id": {
-      GET: (req) => {
-        return new Response(JSON.stringify({ id: req.params.id }));
-      },
-    },
-  },
-  // optional websocket support
-  websocket: {
-    open: (ws) => {
-      ws.send("Hello, world!");
-    },
-    message: (ws, message) => {
-      ws.send(message);
-    },
-    close: (ws) => {
-      // handle close
-    }
-  },
-  development: {
-    hmr: true,
-    console: true,
-  }
-})
-```
-
-HTML files can import .tsx, .jsx or .js files directly and Bun's bundler will transpile & bundle automatically. `<link>` tags can point to stylesheets and Bun's CSS bundler will bundle.
-
-```html#index.html
-<html>
-  <body>
-    <h1>Hello, world!</h1>
-    <script type="module" src="./frontend.tsx"></script>
-  </body>
-</html>
-```
-
-With the following `frontend.tsx`:
-
-```tsx#frontend.tsx
-import React from "react";
-import { createRoot } from "react-dom/client";
-
-// import .css files directly and it works
-import './index.css';
-
-const root = createRoot(document.body);
-
-export default function Frontend() {
-  return <h1>Hello, world!</h1>;
-}
-
-root.render(<Frontend />);
-```
-
-Then, run index.ts
-
-```sh
-bun --hot ./index.ts
-```
-
-For more information, read the Bun API docs in `node_modules/bun-types/docs/**.mdx`.

 This repo is used to store and discuss design decisions, features and significant changes in Vortex, either in specific APIs, 3rd-party integrations or the conceptual model.
 
+## What needs an RFC?
+
+Vortex is a rapidly changing open source project that provides a file format, a compute toolkit, and a set of Rust libraries implementing a range of state-of-the-art compression codecs.
+
+Most development decisions in Vortex happen through the Discussions functionality. Simply open a new discussion describing the kind of change you'd like to make to the project, and if the maintainers like it, open a PR.
+
+This is a great process for bug fixes, simple features and purely additive changes.
+
+However, if you are making a significant change to the way Vortex functions, you may need to write an RFC first. Some example changes that would require an RFC:
+
+* Making a risky change to the format, such as adding new required fields to file metadata
+* Rearchitecting core components of Vortex, or wide-ranging refactors that might break language bindings
+* Creating new libraries or SDKs that we expect others to adopt
+* Making changes to subsystems that are likely to affect performance if not done thoughfully, such as the core IO traits
+
 ## Process
 
 The general process is that changes should be opened as PRs, with the discussion happening in comments on top of it.
