+## Localization
+
+### Localization guidelines
+
+- Meaning is more important than a 1:1 translation! If a sentence sounds weird in your language, you are not only allowed, but advised to change that to sound better, as long as it keeps the original meaning.
+- If you aren't sure about a translation for a word or idiom, ask in the [#localization channel in the Discord server](https://discord.gg/egYeXEvzYv): someone who speaks your language might be able to help you.
+
+### Localizing the website
+
+At the time of writing the only part of the project ready to be localized is the [main website](https://www.pretendo.network).
+
+- Make sure to translate the strings from the working branch ([dev](https://github.com/PretendoNetwork/website/tree/dev)) and not the release branch ([master](https://github.com/PretendoNetwork/website/tree/master)), as the ones in the master branch are likely outdated.
+
+To localize the website, translate the contents of the [`US_en.json`](https://github.com/PretendoNetwork/website/blob/dev/locales/US_en.json) file from `/locales` into a file named REGION_language.json (e.g. `UK_en.json`, `IT_it.json`, `DE_de.json`, etc.).
+ 
+When you're translating the json file, make sure to only translate the correct strings!
+This example snippet should give you a general idea of what to edit:
+```JSON
+{
+  "faq": {
+    "title": "Edit this text",
+    "text": "Edit this text",
+    "QAs": [
+      {
+        "question": "Edit this text",
+        "answer": "Edit this text"
+      }
+    ]
+  }
+}
+```
+Obviously you shouldn't change proper names or links.
+
+You can also use [this **unofficial** tool](https://localization.pretendo.tk) to test your translation file for the website.
