+To create a new translation of File Shredder, open POEdit and select `Create new translation from POT file`, and in the file selection dialog select the `com.github.ADBeveridge.Raider.pot` in the `po` directory.

+## Updating Translations
 Whenever you add or update a translation, please also update the source translation from source code changes with this command in the project's root directory:
 ```sh
 xgettext --from-code=UTF-8  --add-comments --keyword=_ --keyword=C_:1c,2 --output=po/com.github.ADBeveridge.Raider.pot -f po/POTFILES
 ```
+Then open your translation in POEdit and click `Update from POT File`, which is under the `Translation` menu. Retranslate and open a pull request on GitHub, and I should merge it in a few days.

 Thank you for translating this project.
