Hello,
Indeed, only the reference manual (for the keywords) is currently available for ARTEMIS in the documentation folder.
You can get an old documentation for release 6.2 of ARTEMIS:
www.opentelemac.org/index.php/manuals/su...is-documentation-6-2
User manual both in French and English, but validation cases only described in French.
You must pay attention that some features have been updated or new ones have been appeared since 2012.
Please read the NEWS.txt file (same level as sources or documentation) for release 7.3 to see the last main features for ARTEMIS.
Anyway, that may help you for a basic use,
Chi-Tuan
