+
+## Primeros pasos
+
+### Instalación
+
+```bash
+npm install react-easy-modals
+```
+
+### Agrega ModalProvider a tu aplicación
+
+Envuelve tu aplicación con `ModalProvider` para habilitar los modales:
+
+```tsx
+import { ModalProvider } from "react-easy-modals";
+
+function App() {
+  return <ModalProvider>{/* Your app content */}</ModalProvider>;
+}
+
+export default App;
+```
+
+### Crea tu componente Modal
+
+Crea un componente modal básico:
+
+```tsx
+function Modal({ title, message, close, isOpen }) {
+  if (!isOpen) return null;
+
+  return (
+    <div className="modal-backdrop">
+      <div className="modal">
+        <strong>{title}</strong>
+        <p>{message}</p>
+        <button onClick={() => close()}>OK</button>
+      </div>
+      <style jsx>{`
+        .modal-backdrop {
+          position: fixed;
+          z-index: 50;
+          inset: 0;
+          background: rgba(0, 0, 0, 0.5);
+          display: flex;
+          align-items: center;
+          justify-content: center;
+        }
+        .modal {
+          color: white;
+          background: black;
+          border: 1px solid gray;
+          padding: 20px;
+          display: flex;
+          flex-direction: column;
+          gap: 10px;
+          width: 300px;
+        }
+        .modal button {
+          background: white;
+          color: black;
+          padding: 5px;
+        }
+      `}</style>
+    </div>
+  );
+}
+```
+
+### Ponlo a prueba
+
+Importa `useModals` en cualquier parte de tu aplicación para abrir o cerrar tus modales:
+
+```tsx
+import { useModals } from "react-easy-modals";
+import Modal from "./Modal";
+
+function Page() {
+  const modals = useModals();
+
+  async function handleClick() {
+    const result = await modals.open(Modal, {
+      title: "Alert",
+      message: "This is an alert",
+    });
+    console.log(result);
+  };
+
+  return <button onClick={handleClick}>Open Modal</button>;
+}
+```
