+## Build Commands
+
+```bash
+bun run dev              # Development: runs build.js + tailwindcss --watch
+bun run build            # Production build → extension/output
+bun run package:chrome   # Creates extension/releases/nostrconnect_chrome.zip
+bun run package:firefox  # Creates extension/releases/nostrconnect_firefox.xpi
+bun run lint             # Run Biome linter

+bun run test             # Run tests with Vitest
+bun run test:watch       # Run tests in watch mode
+```
+
+## Key Facts
+
+- **Package manager**: bun (preferred) or pnpm. Uses `@jsr` registry for `@nostr/tools`
+- **Build output**: `extension/output/` (not `dist/`)
+- **Ignore `extension/output/`**: It contains generated JS/HTML/CSS and is gitignored
+- **Tailwind source**: `extension/style.css` → `extension/output/style.css`
+
+## Architecture
+
+| File                                     | Purpose                                                   |
+| ---------------------------------------- | --------------------------------------------------------- |
+| `background.js`                          | Core logic: state, permissions, crypto (signEvent, nip04) |
+| `nostr-provider.js`                      | Injected into web pages, provides `window.nostr`          |
+| `content-script.js`                      | Bridges provider ↔ background via postMessage             |
+| `popup.jsx`, `prompt.jsx`, `options.jsx` | React UI components                                       |
+| `extension/chrome/manifest.json`         | Chrome Manifest V3 config                                 |
+| `extension/firefox/manifest.json`        | Firefox Manifest V2 config                                |
+
+The build script (`build.js`) auto-selects the correct manifest based on `prod`/`firefox` args.

+# Nostr Signer (formerly Nostr Connect)

-### notes and other stuff signed by an extension
+A Nostr Signer Extension - sign [nostr](https://github.com/nostr-protocol/nostr) events on web-apps without giving them your keys. Forked from [nos2x](https://github.com/fiatjaf/nos2x) with a fancy UI, crafted by Karnage.

-## Nostr Signer Extension
+## Features

-Use this to sign [Nostr](https://github.com/nostr-protocol/nostr) events on web-apps without having to give them your keys.
-
-It implements [NIP-07](https://github.com/nostr-protocol/nips/blob/master/07.md), i.e. provides a `window.nostr` object which has the following methods:
+Implements [NIP-07](https://github.com/nostr-protocol/nips/blob/master/07.md) and more:

 ```
 async window.nostr.getPublicKey(): string // returns your public key as hex
 async window.nostr.signEvent(event): Event // returns the full event object signed
 async window.nostr.getRelays(): { [url: string]: RelayPolicy } // returns a map of relays
-async window.nostr.nip04.encrypt(pubkey, plaintext): string // returns ciphertext+iv as specified in nip04
-async window.nostr.nip04.decrypt(pubkey, ciphertext): string // takes ciphertext+iv as specified in nip04
+async window.nostr.nip04.encrypt(pubkey, plaintext): string // NIP-04 encryption
+async window.nostr.nip04.decrypt(pubkey, ciphertext): string // NIP-04 decryption
+async window.nostr.nip44.encrypt(pubkey, plaintext): string // NIP-44 encryption
+async window.nostr.nip44.decrypt(pubkey, ciphertext): string // NIP-44 decryption
 ```

-This extension is Chromium-only. For a maintained Firefox fork, see [nos2x-fox](https://diegogurpegui.com/nos2x-fox/).

+Privacy Policy
+==============
+
+**Nostr Signer** doesn't collect any personal data, doesn't track websites you visit, doesn't collect any form of usage analytics, doesn't sends any information to any service over the internet -- in fact, it doesn't even have a server anywhere, it's just an extension installed in your computer.
+
+The only places **Nostr Signer** sends information to are the URL endpoints you define in the settings page for the extension, the URLs that identify the Lightning nodes you want to talk to, which **Nostr Signer** assumes are under your control or under the control of a third-party you trust.
+
+**Nostr Signer** stores only the information you explicitly write in the settings page: _node URL_, _username_ and _password_ (where applicable). That information, however, is only stored in your own browser, using the _local_ storage mode, not the _synced_ storage mode that saves data to a browser-determined sync server. So if the guarantees offered by the browser itself hold true _that information never leaves your browser_.
+
+For more information on the browser guarantees on which **Nostr Signer** depends, please read Firefox's [Privacy Policy](https://www.mozilla.org/en-US/privacy/websites/) and [Terms of Service](https://www.mozilla.org/en-US/about/legal/terms/mozilla/) and Google Chrome [Privacy Policy](https://policies.google.com/privacy) and [Terms of Service](https://ssl.gstatic.com/chrome/webstore/intl/en-US/gallery_tos.html).
