-Author: Ludy87
-Description: This script processes .properties files for localization checks. It compares translation files in a branch with
-a reference file to ensure consistency. The script performs two main checks:
-1. Verifies that the number of lines (including comments and empty lines) in the translation files matches the reference file.
-2. Ensures that all keys in the translation files are present in the reference file and vice versa.
-
-The script also provides functionality to update the translation files to match the reference file by adding missing keys and
-adjusting the format.
-
-Usage:
-    python check_language_properties.py --reference-file <path_to_reference_file> --branch <branch_name> [--actor <actor_name>] [--files <list_of_changed_files>]

+## Frontend Translation Files (TOML Format)
 
-- Edit the file: [languages.html](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/app/core/src/main/resources/templates/fragments/languages.html)
+### Add Language Directory and Translation File
 
+1. Create a new language directory in `frontend/public/locales/`
+   - Use hyphenated format: `pl-PL` (not underscore)
 
-For example, to add Polish, you would add:
+2. Copy the reference translation file:
+   - Source: `frontend/public/locales/en-GB/translation.toml`
+   - Destination: `frontend/public/locales/pl-PL/translation.toml`
 
-```html
-<div th:replace="~{fragments/languageEntry :: languageEntry ('pl_PL', 'Polski')}" ></div>
-```
+3. Translate all entries in the TOML file
+   - Keep the TOML structure intact
+   - Preserve all placeholders like `{n}`, `{total}`, `{filename}`, `{{variable}}`
+   - See `scripts/translations/README.md` for translation tools and workflows
 
-The `data-bs-language-code` is the code used to reference the file in the next step.
+4. Update the language selector in the frontend to include your new language
 
-### Add Language Property File
-
-Start by copying the existing English property file:
-
-- [messages_en_GB.properties](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/app/core/src/main/resources/messages_en_GB.properties)
-
-Copy and rename it to `messages_{your data-bs-language-code here}.properties`. In the Polish example, you would set the name to `messages_pl_PL.properties`.
-
-Then simply translate all property entries within that file and make a Pull Request (PR) into `main` for others to use!
-
-If you do not have a Java IDE, I am happy to verify that the changes work once you raise the PR (but I won't be able to verify the translations themselves).
+Then make a Pull Request (PR) into `main` for others to use!
 
 ## Handling Untranslatable Strings
 
-Sometimes, certain strings in the properties file may not require translation because they are the same in the target language or are universal (like names of protocols, certain terminologies, etc.). To ensure accurate statistics for language progress, these strings should be added to the `ignore_translation.toml` file located in the `scripts` directory. This will exclude them from the translation progress calculations.

+- Use the scripts in `scripts/translations/` to validate and manage translations (see `scripts/translations/README.md`)
 
 Make sure to place the entry under the correct language section. This helps maintain the accuracy of translation progress statistics and ensures that the translation tool or scripts do not misinterpret the completion rate.
