-## Repository overview
+---
 
-This is the **projectbluefin.io** marketing website — a multi-SPA project built with [Vite](https://vitejs.dev/) and [Vue 3](https://vuejs.org/). It contains three sub-apps:
+## Prerequisites
 
-| Directory | Purpose |
-|-----------|---------|
-| `bluespeed/` | Main Bluefin landing page |
-| `dakota/` | Dakota variant landing page |
-| `knuckle/` | Knuckle bare-metal installer page |
-| `public/` | Static assets served as-is |
+| Tool | Version | Purpose |
+|------|---------|---------|
+| [Node.js](https://nodejs.org/) | 24+ (current LTS) | Runtime + build toolchain |
+| [npm](https://www.npmjs.com/) | bundled with Node.js | Package manager |
+| [just](https://github.com/casey/just) | any | Optional — wraps common npm commands |
 
-## Local development
+Install Node.js via your system package manager, [nvm](https://github.com/nvm-sh/nvm),
+or the [official installer](https://nodejs.org/en/download/).
 
-### Prerequisites
+---
 
-- [Node.js](https://nodejs.org/) v18 or higher
-- [npm](https://www.npmjs.com/)
-- Optional: [just](https://github.com/casey/just) for simplified commands
-
-### Setup
+## Local Development
 
 ```bash
-git clone https://github.com/projectbluefin/website
+# 1. Clone the repo
+git clone https://github.com/projectbluefin/website.git
 cd website
-npm install
-```
 
-### Dev server
+# 2. Install dependencies
+npm install
 
-```bash
-npm run dev        # Start development server (hot reload)
-npm run build      # Build for production
-npm run preview    # Preview the production build locally
+# 3. Start the dev server (http://localhost:5173)
+npm run dev
+# or, if you have just installed:
+just serve
 ```
 
-With `just`:
-```bash
-just build         # Build for production
-just serve         # Preview the production build locally
+The dev server supports hot module replacement — changes to `.vue` files and
+locale JSON are reflected instantly without a full page reload.
+
+### Other useful commands
+
+| Command | What it does |
+|---------|-------------|
+| `npm run dev` | Start the local dev server |
+| `npm run preview` | Preview a production build locally |
+| `npm run lint` | Check for linting / formatting issues |
+| `npm run lint:fix` | Auto-fix linting and formatting issues |
+| `npm run typecheck` | TypeScript type check (via `vue-tsc`) |
+| `just build` / `npm run build` | Build for production (not needed for PRs) |

 ```
 
-### Linting and formatting
+The site uses Vite's
+[multi-page app](https://vitejs.dev/guide/build.html#multi-page-app) mode.
+Each subdirectory (`dakota/`, `knuckle/`, `bluespeed/`) is a separate HTML
+entry point that mounts its own Vue app root. They share the same `src/`
+source tree and all locale data.
 
-The project uses [`@antfu/eslint-config`](https://github.com/antfu/eslint-config) for linting and formatting. Run before submitting a PR:
+See [TRANSLATION-GUIDE.md](TRANSLATION-GUIDE.md) for the full i18n workflow.
 
-```bash
-npm run lint        # Lint
-npm run lint:fix    # Lint and auto-fix
-npm run typecheck   # Type-check with vue-tsc
-```

+
+## Making Changes
+
+### Main website content
+
+Text strings that appear on the main site live in `src/locales/en-US.json`.
+Visual layout and logic live in the Vue components under `src/components/sections/`
+and `src/components/scenes/`.
+
+### Adding or editing a component
+
+Components follow the
+[Vue 3 `<script setup>` / Composition API](https://vuejs.org/api/sfc-script-setup.html)
+style. Keep new components in the most specific subdirectory (`common/`,
+`sections/`, `dakota/`, `knuckle/`, etc.).
 
-## Adding a new language (i18n)
+### Translations
 
-1. Copy an existing locale file from `src/locales/` (e.g., `enUS.json`)
-2. Name your file following [Navigator.language](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/language) (e.g., `ptBR.json`)
-3. Translate all values — keep all keys identical to `enUS.json`
-4. Open a PR; CI will validate the JSON schema
+To add or update a translation, edit (or create) the relevant file in
+`src/locales/`. See [TRANSLATION-GUIDE.md](TRANSLATION-GUIDE.md) for a full
+walkthrough, including which fields support Markdown or HTML.
 
-## Testing
+---
 
-Run tests locally before opening a PR.
+## Code Style and Formatting
 
-**Unit tests** (Vitest — fast, no browser needed):
+This project uses [ESLint](https://eslint.org/) via
+[@antfu/eslint-config](https://github.com/antfu/eslint-config) for both
+**linting and formatting** — there is no separate Prettier config. Key rules:
+
+- **Indent:** 2 spaces
+- **Quotes:** single quotes
+- **CSS / `<style>` blocks:** formatted via Prettier (via `eslint-plugin-format`)
+- **`console.log` is banned** — use `console.info`, `console.warn`, or
+  `console.error` instead
+
+Before opening a PR, run the auto-fixer:
 
 ```bash
-npm run test:run    # run once and exit
-npm test            # run in watch mode
+npm run lint:fix
 ```
 
-**Navbar visual tests** (Playwright — requires a running dev server):
+If `npm run lint` reports errors that `--fix` cannot auto-correct, address them
+manually before submitting.
 
-```bash
-npm run dev &                   # start dev server (or in a separate terminal)
-node tests/navbar-visual.mjs    # 38 assertions against navbar rendering
+---
+
+## Submitting a Pull Request
+
+1. **Fork** the repository and create a branch from `main`.
+2. **Make your change** — keep the scope focused.
+3. **Run the linter** — `npm run lint:fix` then `npm run lint` must be clean.
+4. **Sign your commits** (DCO required):
+   ```bash
+   git commit -s -m "fix(locales): correct German translation for Landing.Title"
+   ```
+5. **Open a PR** against `main` and fill out the description.
+
+### Commit message convention
+
+Use conventional commits: `<type>(<scope>): <short description>`
+
+Common types: `feat`, `fix`, `docs`, `chore`, `i18n`, `style`, `refactor`
+
+Examples:
+```plaintext
+feat(knuckle): add download counter to hero section
+fix(locales): correct typo in fr-FR Mission.Text.Change
+i18n: add Polish (pl-PL) locale
+docs: expand CONTRIBUTING guide
 ```
 
-The Playwright tests check that the navigation bar renders correctly at various viewport widths. Run them after any change to `TopNavbar.vue` or layout-affecting CSS.
+### DCO — Developer Certificate of Origin
+
+All commits must be signed with `-s` (`--signoff`). This adds a
+`Signed-off-by:` trailer certifying you have the right to submit the
+contribution under the project's license.
 
-## PR workflow
+```bash
+# Sign a new commit
+git commit -s -m "your message"
+
+# Add sign-off to the most recent commit
+git commit --amend -s --no-edit
+```
 
-1. Fork the repo and create a branch: `git checkout -b feat/my-change`
-2. Make your changes
-3. Run linting, unit tests, and the navbar visual tests (see **Testing** above)
-4. Commit with a [Conventional Commits](https://www.conventionalcommits.org/) message: `feat(section): add X`
-5. Push and open a PR against `main`
-6. All PRs require at least 1 approving review from a maintainer before merging
