-## Managing Dependencies
-
-When adding new dependencies or updating existing ones in Stirling-PDF, follow these steps to ensure proper verification and security:
-
-1. Update the dependency in `build.gradle`:
-```groovy
-dependencies {
-    // Add or update your dependency
-    implementation "com.example:new-library:1.2.3"
-}
-```
-
-2. Generate new verification metadata and keys:
-```bash
-# Generate verification metadata with signatures and checksums
-./gradlew clean dependencies buildEnvironment spotlessApply --write-verification-metadata sha256,pgp
-
-# Export the .keys file 
-./gradlew --export-keys
-```
-
-3. Files to commit:
-   - `build.gradle` - Your dependency changes
-   - `gradle/verification-metadata.xml` - Contains verification rules and checksums
-   - `gradle/verification-keyring.keys` - Contains PGP keys in text format
-
-4. Verify the build works with the new verification:
-```bash
-./gradlew build
-```
-
-5. Before committing, check:
-   - Verify any new BOM files are properly handled in verification metadata
-   - Review the changes in `verification-metadata.xml` to ensure they match your dependency updates
-
-This ensures dependencies are properly verified and secure while maintaining transparency in the repository.

HowToAddNewLanguage.md

@@ -11,16 +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 class="dropdown-item lang_dropdown-item" href="" data-bs-language-code="pl_PL">
-    <img 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.
