+# MetaMask Translation Guide
+
+The MetaMask browser extension supports new translations added in the form of new locales files added in `app/_locales`.
+
+- [The MDN Guide to Internationalizing Extensions](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Internationalization)
+
+## Adding a new Language
+
+Each supported language is represented by a folder in `app/_locales` whose name is that language's subtag ([look up a language subtag using this tool](https://r12a.github.io/app-subtags/)).
+
+Inside that folder there should be a `messages.json` file that follows the specified format. An easy way to start your translation is to first duplicate `app/_locales/en/messages.json` (the english translation), and then update the `message` key for each in-app message.
+
+That's it! When MetaMask is loaded on a computer with that language set as the system language, they will see your translation instead of the default one.
+
+## Testing
+
+To automatically see if you are missing any phrases to translate, we have a script you can run (if you know how to use the command line). The script is:
+
+```
+node development/verify-locale-strings.js $YOUR_LOCALE
+```
+
+Where `$YOUR_LOCALE` is your [locale string](https://r12a.github.io/app-subtags/), i.e. the name of your language folder.
+
+To verify that your translation works in the app, you will need to [build a local copy](https://github.com/MetaMask/metamask-extension#building-locally) of MetaMask. You will need to change your browser language, your operating system language, and restart your browser (sorry it's so much work!).
