-to the existing translations and updates to align with changes or additions to the English documentation.
+We highly encourage community translations! We no longer have professional translations, and we believe in the power of our community to provide accurate and helpful translations.
+
+The documentation is translated into these languages:
+- English (`en`)
+- Spanish (`es`)

+To find translations that need to be done, you can [filter for merged PRs](https://github.com/expressjs/expressjs.com/pulls?q=is%3Apr+is%3Aclosed+label%3Arequires-translation-es) that include the tag for your language, such as `requires-translation-es`.
+
+When you contribute a translation, please reference the original PR. This helps the person merging your translation to remove the `requires-translation-es` tag from the original PR.
