+
+# How to add new languages to Stirling-PDF
+
+Fork Stirling-PDF and make a new branch out of Main
+
+Then add reference to the language in the navbar by adding a new language entry to the dropdown
+
+https://github.com/Frooodle/Stirling-PDF/blob/main/src/main/resources/templates/fragments/navbar.html#L80
+
+For example to add Polish you would add 
+```
+<a class="dropdown-item lang_dropdown-item" href="" data-language-code="pl_PL">Polish</a>
+```
+The data-language-code is the code used to reference the file in the next step.
+
+Start by copying the existing english property file 
+
+https://github.com/Frooodle/Stirling-PDF/tree/langSetup/src/main/resources/messages_en_GB.properties
+
+Copy and rename it to messages_{your data-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 PR into main for others to use!
+
+If you do not have a java IDE i am happy to verify the changes worked once you raise PR (but wont be able to verify the translations themselves)
