1_These instructions are incomplete and anyone interested in contributing is invited to discuss on [the TeX-hyphen mailing list](http://tug.org/mailman/listinfo/tex-hyphen)_ 2 3# Contributing pattern files for an existing language. 4 5If you want to modify patterns for a language that already exists in our 6repository, you should make sure that your additions don’t interfere with the 7current patterns. It’s not recommended to manually add patterns to a list 8generated by `patgen`: instead, modifications should be made in the hyphenated 9word list that was used as a source, and the full set should be regenerated. 10This of course does not apply to hand-generated patterns. 11
