 `localStorageProvider` and `sessionStorageProvider` resolve their `globalThis.*Storage` backend lazily on each access instead of capturing it when the module is imported. This makes them safe to import before a browser-like global is available, and lets tests or non-DOM runtimes provide storage later.
 
-### Provider factories
+## Provider factories
 
-For URL-based providers, factory functions allow customizing the history behavior. These providers check for a browser context when the provider is created. If `window.location` or `window.history` is unavailable, they return a no-op provider instead of throwing.
+All built-in providers also have factory functions:
+
+- `createNoopProvider()`
+- `createLocalStorageProvider()`
+- `createSessionStorageProvider()`
+- `createUrlSearchParamsProvider(options?)`
+- `createUrlSearchParamsInHashProvider(options?)`
+
+Use the storage-backed factories when you want a fresh provider instance instead of the default singleton export.
+
+The URL-based factories accept a `push` option to customize navigation behavior. They check for a browser context when the provider is created. If `window.location` or `window.history` is unavailable, they return a no-op provider instead of throwing.
