+Anastasis Documentation
+=======================
+
+Anastasis is Free Software protocol and implementation that allows
+users to securely deposit **core secrets** with an open set of escrow
+providers and to recover these secrets if their original copies are
+lost.
+
+Anastasis is intended for users that want to make backups of key
+material, such as OpenPGP encryption keys, hard disk encryption keys
+or master keys of electronic wallets. Anastasis is NOT intended to
+store large amounts of secret data, it is only designed to safeguard
+key material.
+
+Anastasis solves the issue of keeping key material both available
+to the authorized user(s), and confidential from anyone else.
+
+With Anastasis, the **core secrets** are protected from the Anastasis
+escrow providers by encrypting each with a **master key**.  The
+**master key** can be split and distributed across the escrow
+providers to ensure that no single escrow provider can recover the
+**master key** on its own.  Which subset(s) of Anastasis providers
+must be contacted to recover a **master key** is freely configurable.
+
+With Anastasis, users can reliably recover their **core secret**,
+while Anastasis makes this difficult for everyone else.  This is even
+true if the user is unable to reliably remember any secret with
+sufficiently high entropy: Anastasis does not simply reduce the
+problem to encrypting the **core secret** using some other key
+material in possession of the user.
