+===========
+
+Generate keychain
+-----------------
+All data stored using darc is protected by 256 bit AES encryption. This means
+that a keychain file needs to be created before any archives can be created:
+
+$ darc init-keychain
+
+This will create a password protected keychain in ~/.darc/keychain
+

+--------------------------
+
+$ darc init /path/store
+
+Create an archive
+-----------------
+
+$ darc create /path/store::MyBackup ~/Documents ~/src
+
+List store contents
+-------------------
+
+$ darc list /path/store
+
