# Contributing to OpenConnect

## Translations

The main thing needed at the present time is translations into languages other than English. All contributions will be gratefully received.

Translations for OpenConnect can be entered through Transifex or by editing one of the language files in the `po/` directory and sending the resulting patch (or file) to the mailing list.

If there are questions about the messages because the intent is not clear, or if the messages could be improved to make translation easier or better, please also feel free to ask or make suggestions on the mailing list.

## TODO

Other items on the TODO list include:

- Better support for running or emulating the 'Cisco Secure Desktop' trojan.
- More platform support: Windows, Symbian, etc.
- GUI for OS X, perhaps based on Tunnelblick.

Patches can be sent to the mailing list or directly to the author in private email.
