The currently displayed language can be changed in a number of ways:

• On the project Login page.
  The user can select their desired language when they login to the project.
  
  

• Using a Language Selector component in the project.
  This component displays the languages that have translations available, and changes the current language based on selection.
  

• With the system.util.setLocale() function.
  This function takes an ISO 639-1 two-letter code for the language to use (for example, "en", "fr", "de", "es", and so on).
