+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+- `lib/` contains the Ruby framework code; tests live alongside source as `*.test.rb` (e.g., `lib/mayu/state.rb` → `lib/mayu/state.test.rb`).
+- `lib/mayu/client/` holds the browser runtime (Node workspace).
+- `example/` is a runnable sample app plus `mayu.toml` server config.
+- `bin/` and `exe/` provide CLI entry points and scripts.
+- `vendor/` and `node_modules/` are dependency/vendor directories.
+
+## Architecture Overview
+
+- Server-rendered HTML with server-side state; the client runtime applies DOM patches over streaming updates.
+- Components return VDOM descriptors; the server diffs component trees and sends patch instructions.
+- Client stream and event serialization live under `lib/mayu/client/src/` and `lib/mayu/client/src/serializeEvent.ts`.
+
+## Build, Test, and Development Commands
+
+- `bundle install` installs Ruby dependencies.
+- `npm install` installs Node dependencies (root workspace).
+- `npm run build` builds the browser runtime via the `lib/mayu/client` workspace.
+- `rake test` runs the Minitest suite (glob: `lib/**/*.test.rb`).
+- `rake build` runs the client production build and builds the gem.
+- `cd example && bundle install && bin/mayu dev` starts the example app at `https://localhost:9292/`.
+
+## Coding Style & Naming Conventions
+
+- Ruby code uses `.rb` with adjacent tests named `*.test.rb`.
+- Prettier is configured (with `@prettier/plugin-ruby`) and is used via `npx prettier --write '**/*'`.
+- `lint-staged` runs Prettier on common file types before commits; keep changes formatted.
+
+## Testing Guidelines
+
+- Test framework: Minitest (see `test_helper.rb` and `Rakefile`).
+- Prefer higher-level tests; add focused unit tests for tricky edge cases.
+- Keep example app behavior up to date; it serves as a practical integration test.
+
+## Commit & Pull Request Guidelines
+
+- Commit messages in this repo are short, imperative sentences (e.g., “Fix margins”, “Update dependencies and modernize code”).
+- Include a clear PR description, link issues when relevant, and add screenshots/gifs for UI changes.
+- Confirm tests (`rake test`) and build (`npm run build`) before opening a PR.
+
+## Security & Configuration Tips
+
+- Development HTTPS uses a self-signed certificate; follow README instructions if your browser blocks `https://localhost:9292/`.
+- Server settings live in `example/mayu.toml`; use `[dev.server]` options for local development.
