HowToAddNewLanguage.md

@@ -11,14 +11,12 @@ Fork Stirling-PDF and create a new branch out of `main`.
 Then add a reference to the language in the navbar by adding a new language entry to the dropdown:
 
 - Edit the file: [languages.html](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/src/main/resources/templates/fragments/languages.html)
-- Add a flag SVG file to: [flags directory](https://github.com/Stirling-Tools/Stirling-PDF/tree/main/src/main/resources/static/images/flags)
 
-Any SVG flags are fine; most of the current ones were sourced from [here](https://flagicons.lipis.dev/). If your language isn't represented by a flag, choose a similar one, such as Saudi Arabia's flag for Arabic.
 
 For example, to add Polish, you would add:
 
 ```html
-<a th:if="${#lists.isEmpty(@languages) or #lists.contains(@languages, 'pl_PL')}" class="dropdown-item lang_dropdown-item" href="" data-bs-language-code="pl_PL"> <img th:src="@{'/images/flags/pl.svg'}" alt="icon" width="20" height="15"> Polski</a>
+<div th:replace="~{fragments/languageEntry :: languageEntry ('pl_PL', 'Polski')}" ></div>
 ```
 
 The `data-bs-language-code` is the code used to reference the file in the next step.
