If you want to help this project on translating its documentation to English, see this source file, it uses LaTeX: klavaro-dok-1.0.8.tar.gz. Then, you are supposed to translate from Portuguese or from Esperanto, of course.
Anyway, an article about Klavaro, in the blog Penguin Sightings may be very useful. It's nicely written, the description is very clear.
