When the option "Folder translations" in pAdmin is activated  and the user has the required permissions a new button appears. (see Figure 1)

Figure 1

When this button is clicked the translation interface gets opened. (see Figure 2)

Figure 2

Here you have the option to translate the field:

• Title
• Shortname
• Top description
• Bottom description

The language you want to translate to should be selected first. As you can see in Figure 2 here it can be switched between english and german (Switch to: English | Deutsch).

If you want to translate to other languages, you should activate them in pAdmin.
