+## I18N
+
+### Install i18n-ally Plugin
+
+1. Open the Extensions Marketplace in VSCode, search for and install the `i18n Ally` plugin.
+
+### Code Optimization Examples
+
+#### Fetch Specific Namespace Translations in `getServerSideProps`
+
+```typescript
+// pages/yourPage.tsx
+export async function getServerSideProps(context: any) {
+  return {
+    props: {
+      currentTab: context?.query?.currentTab || TabEnum.info,
+      ...(await serverSideTranslations(context.locale, ['publish', 'user']))
+    }
+  };
+}
+```
+
+#### Use useTranslation Hook in Page
+
+```typescript
+// pages/yourPage.tsx
+import { useTranslation } from 'next-i18next';
+
+const YourComponent = () => {
+  const { t } = useTranslation();
+
+  return (
+    <Button variant="outline" size="sm" mr={2} onClick={() => setShowSelected(false)}>
+      {t('common:close')}
+    </Button>
+  );
+};
+
+export default YourComponent;
+```
+
+#### Handle Static File Translations
+
+```typescript
+// utils/i18n.ts
+import { i18nT } from '@packages/i18n/utils';
+
+const staticContent = {
+  id: 'simpleChat',
+  avatar: 'core/workflow/template/aiChat',
+  name: i18nT('app:template.simple_robot')
+};
+
+export default staticContent;
+```
+
+### Standardize Translation Format
+
+- Use the t(namespace:key) format to ensure consistent naming.
+- Translation keys should use lowercase letters and underscores, e.g., common.close.
