Just go to https://www.transifex.com/projects/p/symbiose-webos/ and start translating. ;-)

Then, you can update the webos's translations files by running grunt transifex.

Alternatively, you can edit directly files to translate.

Firstly, you will have to translate strings in /usr/share/locale.

Files must be copied from an existing translation (/usr/share/locale/fr_FR) to a new directory /usr/share/locale/localeName. The locale name is the same as on POSIX platforms (see https://en.wikipedia.org/wiki/Locale). For example, en_AU is for Australian English.

Then, you can translate apps titles and descriptions here : /usr/share/applications. Categories are here : /usr/share/categories.

Some strings cannot be translated in a few number of apps. Please report these apps on the bug tracker.
