+Encrypted secrets management with master password protection.
+
+This module provides secure storage for sensitive configuration like API keys,
+using Argon2id for password-based key derivation and Fernet (AES-256) for encryption.
+
+Basic usage:
+    from secrets_manager import SecretsStore
+
+    # First time setup
+    store = SecretsStore()
+    store.initialize("my-master-password")
+    store.set("ANTHROPIC_API_KEY", "sk-ant-...")
+
+    # Later usage
+    store = SecretsStore()
+    store.unlock("my-master-password")
+    api_key = store.get("ANTHROPIC_API_KEY")
+
+Command-line interface:
+    python -m secrets_manager.cli init
+    python -m secrets_manager.cli set KEY VALUE
+    python -m secrets_manager.cli get KEY
+    python -m secrets_manager.cli list
+    python -m secrets_manager.cli change-password
