With Helpinator you can create documentation in different languages from the same project file. To add new languages to the project click "plus" sign on the language bar:
Check as many languages as you like and click "OK".
Almost every item in the Helpinator project can be language-specific. For every language you can have separate:
1. Topic content
3. Variable values
4. Text snippets
5. PDF/RTF and CHM/Web Help templates.
Library images are the same for all languages.
Note that you can not have different topic tree in different languages. Tree is always the same, only topic titles change.
To select language you want to edit, select it in the language drop-down list on the language bar.
When you click "Compile" buttons currently selected language is used.
