+# Translations Guidelines
+
+## Overview
+Translations for the "DualShock Calibration GUI" project are managed through
+JSON files located in the [lang/ directory](https://github.com/dualshock-tools/dualshock-tools.github.io/tree/main/lang). 
+
+This document provides guidelines on how to contribute translations for new languages.
+
+## Getting Started
+To translate the project into a new language, follow these steps:
+
+1. **Duplicate an Existing File**: Start by duplicating an existing language file located in the `lang/` directory. For example, if you're translating into Spanish, duplicate `lang/it_it.json` and rename it to `lang/es_es.json`.
+
+2. **Edit the File**: Open the duplicated JSON file and replace the translations of strings with the corresponding translations in the target language. The first entry `.authorMsg` is customizable, write there your name and, if you want, your website!
+
+3. **Save the File**: Save the changes to the JSON file.
+
+4. **Update `core.js`**: Add the new language to the list of available languages (`available_langs`) in [core.js](https://github.com/dualshock-tools/dualshock-tools.github.io/blob/main/core.js). For example:
+   
+```json
+var available_langs = {
+    "zh_cn": { "name": "Chinese", "file": "zh_cn.json"},                        
+    "fr_fr": { "name": "Français", "file": "fr_fr.json"},                       
+    "hu_hu": { "name": "Hungarian", "file": "hu_hu.json"},                      
+    "it_it": { "name": "Italiano", "file": "it_it.json"}, 
+    "es_es": { "name": "Español", "file": "es_es.json"},
+};
+```
+
+## Submitting Translations
+Once you have completed the translation, you can contribute it in one of the following ways:
+
+- **Pull Request (PR)**: Open a Pull Request with the changes.
+- **Discord**: Send the translated file to `the_al` on Discord.
+- **Email**: Send the translated file to `ds4@the.al` via email.
+
+Feel free to adjust any details or formatting according to your preferences!

+make this project accessible to a wider audience. Thank you!
