-# lightningtimer
+# Lightning Timer
+
+A focused, full-screen countdown timer for lightning talks, built as a static SvelteKit app.
+
+## Features
+
+- Configurable duration with quick 3, 5, 7, and 10 minute presets
+- Viewport-filling countdown display
+- Yellow numerals for the final minute
+- Red numerals for the final 15 seconds
+- Red background with black numerals when time expires
+- Start, pause, resume, reset, and full-screen controls
+- Keyboard shortcuts: `Space` to start/pause, `R` to reset, and `S` to set the duration
+- Saves the selected duration in local storage
+
+## Development
+
+```sh
+npm install
+npm run dev
+```
+
+## Build
+
+```sh
+npm run check
+npm run build
+```
+
+The static site is generated in `build/`.
+
+## GitHub Pages deployment
+
+The workflow in `.github/workflows/deploy.yml` checks, builds, and deploys the app whenever `main` is pushed. It configures SvelteKit's base path as `/lightningtimer`, so assets work at:
+
+<https://idan.github.io/lightningtimer/>
+
+To enable the first deployment:
+
+1. Push this repository to GitHub.
+2. Open **Settings → Pages** in the repository.
+3. Under **Build and deployment**, select **GitHub Actions** as the source.
+4. Open the **Actions** tab to monitor the deployment.
+
+You can also run the workflow manually from **Actions → Deploy to GitHub Pages → Run workflow**.
