 The default configuration uses **50,000** PBKDF2 iterations. Increase this value for stronger password hashing or lower it for faster startup (not recommended). Offline Mode skips all Nostr communication, keeping your data local until you re-enable syncing. Quick Unlock stores a hashed copy of your password in the encrypted config so that after the initial unlock, subsequent operations won't prompt for the password until you exit the program. Avoid enabling Quick Unlock on shared machines.
 
+### Recovery
+
+If you previously backed up your vault to Nostr you can restore it during the
+initial setup:
+
+1. Start SeedPass and choose option **4** when prompted to set up a seed.
+2. Paste your BIP-85 seed phrase when asked.
+3. SeedPass initializes the profile and attempts to download the encrypted vault
+   from the configured relays.
+4. A success message confirms the vault was restored. If no data is found a
+   failure message is shown and a new empty vault is created.

 ## Running Tests
 
 SeedPass includes a small suite of unit tests located under `src/tests`. **Before running `pytest`, be sure to install the test requirements.** Activate your virtual environment and run `pip install -r src/requirements.txt` to ensure all testing dependencies are available. Then run the tests with **pytest**. Use `-vv` to see INFO-level log messages from each passing test:
