Updating an existing translation for the Jmol application/applet is quite easy. Only a few steps are required to update the translation.
1. Download the files for the translation:
Download Jmol-LANG.po from the Jmol directory.
Download JmolApplet-LANG.po from the JmolApplet directory.
Note: LANG means your language code: e.g. de for German, fr for French and so on.
2. Install an editor for .po files:
See step 2 in the explanations for adding a new translation.
See step 4 in the explanations for Internationalisation/Offline/New translation|adding a new translation]].
4. Send the two .po files to a Jmol developer, so they will be added in the next Jmol release.
(sourceforge mail addresses may refuse mails with .zip attachments, so don't zip the files)
