 # Node.js Website Translation Policy
 
-Node.js is a global platform and so this site has many translations. The translation of the site into
-languages other than English is handled by the localization working group of the language in question. If you
-would like to contribute to the translation of nodejs.org, please refer to the following process:
-
-> Since Apr, 1 2020 translation process moved to [Crowdin](https://crowdin.com/project/nodejs-website)
-
-## Get started
-
-1. Open [nodejs-website](https://crowdin.com/project/nodejs-website) Crowdin project
-2. Find your locale and start translation. Find more details in [guide for volunteer translators](https://support.crowdin.com/for-volunteer-translators/)
-
-All translated and approved content will be pushed to this repo automatically. You don't need to create any PRs with translation. Just keep localization process on Crowdin.
-
-Original source can be found in [/locale/en](https://github.com/nodejs/nodejs.org/tree/main/locale/en). If you find any problem with original source, please create a PR with changes directly to `/locale/en`. Crowdin automatically pull all updates within 24 hours.
-
-### Can't find my locale on Crowdin
-
-Please create a [new issue](https://github.com/nodejs/nodejs.org/issues/new?template=03-i18n.md) in this repo. Crowdin managers team would be happy to add new languages.
-
-## Localization groups
-
-An existing localization group is not required to start translation. You can contribute on Crowdin without it. Think about groups like a basement to communicate with other translators of your locale.
-
-Contact your appropriate localization group, and discuss with them the best possible way to contribute. A list of the localization groups can be found below.
