Glossary
Keep names and terms consistent across a series.
A glossary pins how a name or term is translated. Serifu uses it on every page of every volume that uses the glossary.
Add terms
Open Glossary in the sidebar and add pairs of source and translation, for example 永大 → Eiroku.
Use it for a project
Pick the glossary when you create a project, or in Settings as your default.
Set up the glossary before translating a new series: it is easier than fixing names afterwards.
