Issue:
Multilenguaje 
Seria interesante que haya una documentación que logre adaptarse al lenguaje seleccionado desde un selector. Ya dependería de uno agregar algún lenguaje adicional en nuestra docs del proyecto.

+# Internationalization (i18n)
+
+You can use the `useTheme` composable to configure internationalization in your `.vitepress/theme/index.js` file, or in any `.md` page/file. All values are optional.
+
+```vue
+<script setup lang="ts">
+import { useTheme, locales } from 'vitepress-openapi'
+
+useTheme({
+  i18n: {
+    locale: 'en', // en | es | pt-BR | string
+    fallbackLocale: 'en', // en | es | pt-BR | string
+    messages: {
+      en: {
+        ...locales.en,
+        'custom i18n key': 'Custom i18n value',
+      },
+      es: {
+        ...locales.es,
+        'custom i18n key': 'Valor personalizado i18n',
+      },
+      'pt-BR': {
+        ...locales['pt-BR'],
+        'custom i18n key': 'Valor personalizado i18n',
+    },
+    availableLocales: [
+      { code: 'en', label: 'English' },
+      { code: 'es', label: 'Español' },
+      { code: 'pt-BR', label: 'Português (Brasil)' },
+    ],
+  },
+})
+</script>
+
+<!-- OASpec component or OAOperation component -->
+```
+
+If you're using the built-in VitePress i18n features, you can configure the locale as follows:
+
+```vue
+<script setup lang="ts">
+import { useTheme } from 'vitepress-openapi'
+import { useData } from 'vitepress'
+
+const { lang } = useData()
+
+useTheme({
+  i18n: {
+    locale: lang.value,
+  },
+})
+</script>
+
+<!-- OASpec component or OAOperation component -->
+```
+
+You can see a [Live Example](https://vitepress-openapi-i18n.vercel.app/) and the [Source Code](https://github.com/enzonotario/vitepress-openapi-i18n) for more details.
+
+## `OALocaleSelect` component
+
+You can use the `OALocaleSelect` component to render a select with the available locales. Keep in mind that this will change only `vitepress-openapi` components, not the entire VitePress site. For example, you can add it to Navbar in your `.vitepress/config.js`:
+
+```js
+export default defineConfigWithTheme({
+    themeConfig: {
+        nav: [
+            {
+                component: 'OALocaleSelect',
+            },
+        ],
+    },
+})
+```
