+## Index File Format
+
+All entries belonging to a seed profile are summarized in an encrypted file named `seedpass_entries_db.json.enc`. This index starts with `schema_version` `2` and contains an `entries` object keyed by entry numbers.
+
+```json
+{
+  "schema_version": 2,
+  "entries": {
+    "0": {
+      "website": "example.com",
+      "length": 8,

 ## JSON Schema for Individual Entries
 
 Each SeedPass entry is stored as an individual JSON file, promoting isolated management and easy synchronization with Nostr. This structure supports diverse entry types (`kind`) and allows for future expansions.
