 ### Terminology
 
 - Use the [Localization glossary](https://github.com/OrcaSlicer/OrcaSlicer_WIKI/blob/main/developer_reference/localization_glossary.md) as the source of truth for recurring terms, so the same English term is always rendered the same way within a language, and terms that must stay in English (brand/product names, acronyms, materials, file formats, G-code tokens, macros/variables/identifiers) are not translated.
-- If a term's established translation changes, update both the affected `.po` files and the glossary (`localization_glossary.tsv`, then regenerate) so they stay in sync.
+- If a term's established translation changes, update both the affected `.po` files and the glossary (`developer_reference/glossary/<lang>.tsv` in the wiki, then regenerate) so they stay in sync.
 - Translate the *meaning*, not the words. Check what the string actually controls before translating it — English reuses one word for different things. `Flow ratio` (multiplier), `Flow Rate` (throughput) and `Flow Dynamics` (pressure compensation) are three different terms; `extruder` may mean the toolhead, the feeder motor, or the nozzle depending on the string.
 - Reuse one template per recurring message shape (`Failed to connect to …`, `Are you sure you want to …?`), even where the English wording varies.
