+# Releasing an update
+What to do with these files when releasing an update of this extension
+
+## Chrome
+The [update.xml](./platform/chrome/update.xml) can only contain the latest version.  
+So just update the `codebase` (.crx) link & `version` (X.X.X) attributes.
+
+## Firefox
+The [updates.json](./platform/firefox/updates.json) can contain all versions, even the previous ones.  
+So add an extra element in the `updates` list in this format:
+```json
+{
+    "version": "X.X.X",
+    "update_link": "...xpi"
+}
+```
