 ### Translate the software
 
 QualCoder supports multilingual functionality using two types of translation files:
+
 - Gettext files (.po or .mo), which contain the software translation;
 - QT language files (.ts or .qm) corresponding to the user interface.
 
 To translate:
+
  1. Create a language file (if one does not already exist) using this command: ```python rebuild_lang.py --create --lang LANGUAGE_CODE``` Please note that the names of your language files must comply with the [ISO 639-1](https://fr.wikipedia.org/wiki/Liste_des_codes_ISO_639-1) format.
  2. If a language file already exists, you can update the translations using ```python rebuild_lang.py --update --lang LANGUAGE_CODE```.
  3. You can edit the translations of the files in the src/i18n folder using the [Poedit](https://poedit.net/) software.
