+
+This crate contains traits which provide generic, object-safe APIs for
+generating and verifying [digital signatures][1].
+
+Used by the [`ecdsa`][2] and [`ed25519`][3] crates, with forthcoming support
+in the [`rsa`][4] crate.
+
+See also the [Signatory][5] crate for trait wrappers for using these traits
+with many popular Rust cryptography crates, including `ed25519-dalek`, *ring*,
+`secp256k1-rs`, and `sodiumoxide`.
+
+[Documentation][docs-link]
+
+## Minimum Supported Rust Version
+
+Rust **1.56** or higher.
+
+Minimum supported Rust version can be changed in the future, but it will be
+done with a minor version bump.
+
+## SemVer Policy
+
+- All on-by-default features of this library are covered by SemVer
+- MSRV is considered exempt from SemVer as noted above
+- The off-by-default features `derive-preview` and `digest-preview` are
+  unstable "preview" features which are also considered exempt from SemVer.
+  Breaking changes to these features will, like MSRV, be done with a minor
+  version bump.
