+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+- `src/routes/` contains SvelteKit routes; the primary UI is `src/routes/+page.svelte`.
+- `src/lib/screens/` holds the scrollable “screen” components used by the main page.
+- `src/lib/components/`, `src/lib/utils/`, and `src/lib/state.svelte.ts` contain shared UI, helpers, and state.
+- `src/lib/libraries/` wraps external endpoints and integrations.
+- `src/lib/db.ts`, `src/lib/schema.ts`, and `drizzle/` define and store database schema + migrations.
+- `src/app.css`, `src/app.html`, and `src/app.d.ts` are global app assets/config.
+
+## Build, Test, and Development Commands
+
+Use `bun` for all workflows.
+
+- `bun install` installs dependencies.
+- `bun run dev` starts the Vite dev server.
+- `bun run build` generates a production build.
+- `bun run preview` serves the production build locally.
+- `bun run check` runs `svelte-check` with the repo’s TS config.
+- `bun run lint` checks formatting (Prettier) and lint rules (ESLint).
+- `bun run format` auto-formats the repo with Prettier.
+- `bun run migrate` generates Drizzle migrations and compiles them.
+
+## Coding Style & Naming Conventions
+
+- Formatting is enforced by Prettier and `prettier-plugin-svelte`; run `bun run format`.
+- Linting uses ESLint with Svelte support; run `bun run lint`.
+- Prefer descriptive component names in `src/lib/screens/` and keep route files minimal.
+- Use TypeScript where applicable (`.ts`, `.svelte` with `lang="ts"`).
+
+## Testing Guidelines
+
+- There is no dedicated test framework in this repo.
+- Use `bun run check` and `bun run lint` as the baseline quality gate.
+- If you add tests, keep them near the feature and name them clearly (e.g. `*.test.ts`).
+
+## Commit & Pull Request Guidelines
+
+- Commit messages are short, imperative, and capitalized (e.g., “Fix websockets”, “Add new chains”).
+- PRs should include a concise description, testing performed (commands run), and UI screenshots for visual changes.
+- Link relevant issues or context when available.
+
+## Configuration & Environment
+
+- Copy `.env.example` to `.env` and fill required keys (WalletConnect + Polymer).
+- Cloudflare Workers are the default deployment target; see `svelte.config.js` and `wrangler.jsonc`.

 ### Development
 
 To start development:
+
 1. Copy `.env.example` to `.env`.
 2. Then fill in the `env` variables by creating a [WalletConnect](https://walletconnect.com) project
 3. Also create an [account](https://accounts.polymerlabs.org/) with Polymer to generation [Polymer](https://polymerlabs.org) API keys.
