+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+This is a manifest-only Firefox WebExtension with npm-based development tooling.
+
+- `manifest.json` defines the extension metadata and ChatGPT search provider.
+- `icons/` contains size-specific PNG artwork named `powered-by-openai-icon-<size>x<size>.png`.
+- `web-ext-config.mjs` controls linting, local execution, and ZIP packaging.
+- `.gitea/workflows/firefox-extension.yml` validates pull requests and protected branches.
+- `README.md`, `CHANGELOG.md`, and `LICENSE.txt` cover usage, releases, and licensing.
+
+## Browser Scope
+
+Firefox Desktop is the only current implementation and release target. Do not add Chrome, Brave, Chromium, or other browser packaging—or modify the sibling Chrome repository—unless a task explicitly requests it. Future ports remain desirable, so prefer standard WebExtension APIs where they preserve Firefox behavior and isolate unavoidable Firefox-specific code.
+
+## Build, Test, and Development Commands
+
+- `npm ci` installs the exact dependencies from `package-lock.json`; use Node.js 22 or newer.
+- `npm run dev` launches a temporary Firefox profile with automatic extension reload.
+- `npm run lint` runs strict Mozilla extension validation.
+- `npm run build` creates the unsigned ZIP under `web-ext-artifacts/`.
+- `npm test` runs lint and build checks together; run it before every pull request.
+
+## Coding Style & Naming Conventions
+
+Use two-space indentation in JSON, YAML, and JavaScript configuration. Preserve logical key grouping in `manifest.json`. Use lowercase, hyphenated filenames and include dimensions in icon names. Keep changes focused and avoid adding runtime dependencies without a concrete need.
+
+## Testing Guidelines
+
+Automated checks cover manifest validation and packaging, not browser behavior. After `npm test`, use `npm run dev` and confirm `gpt <query>` opens ChatGPT, the provider stays non-default, and Firefox search settings can configure it. Inspect ZIP contents whenever packaging rules or assets change.
+
+Gitea Actions runs checks for every pull request and pushes to `develop` and `main`. Only successful `main` pushes upload an unsigned build artifact; CI does not publish to AMO.
+
+## Commit & Pull Request Guidelines
+
+Recent history uses short, lowercase prefixes such as `doc:` and `build:` (for example, `doc: fix git url`). Follow `<type>: <concise summary>` and keep each commit focused.
+
+Pull requests should explain the user-visible effect, list manual Firefox checks, and link the relevant issue. Include screenshots for icons or browser-visible metadata. Explicitly call out permission, search URL, privacy, and packaging changes.
+
+## Security & Privacy
+
+Do not commit credentials or API keys. New permissions, telemetry, intermediary servers, or data collection require explicit justification and matching privacy documentation.

-Search with ChatGPT Powered by OpenAI Firefox Extension
-=======================================================
+# Search with ChatGPT Powered by OpenAI Firefox Extension
 
-Extensions adds ChatGPT as a search engine configurable option
-in the browser. Default prefix is "gpt <query term>" or can be set
-in the settings. Does not require login, or API key, or use custom servers
-or code. Simply queries your url bar into a new ChatGPT session.
+This extension adds ChatGPT as a configurable Firefox search provider. Type
+`gpt <query>` in the address bar to open the query in a new ChatGPT session.
+It uses no API key, custom server, or intermediary handler.

+## Browser Support
+
+Firefox Desktop is the current development and release target. Chrome, Brave,
+other Chromium browsers, and additional WebExtension platforms may be evaluated
+after the Firefox feature set is more substantial; they are not current targets.
+
+## Development
+
+Install Node.js 22 or newer, Firefox, and the locked development dependencies:
+
+```sh
+npm ci
+```
+
+Available commands:
+
+- `npm run dev` launches the extension in a temporary Firefox profile and
+  reloads it when files change.
+- `npm run lint` validates the extension and treats warnings as errors.
+- `npm run build` creates
+  `web-ext-artifacts/search-with-chatgpt-firefox-<version>.zip`.
+- `npm test` runs the same lint and build checks used by Gitea Actions.
+
+The generated ZIP is unsigned. Use `npm run dev` for local testing; signing and
+submission to Mozilla Add-ons remain a separate release step.
+
+Before submitting a change, confirm that `gpt <query>` opens
+`https://chatgpt.com?q=<query>`, the provider remains non-default, and it can be
+configured in Firefox search settings.
