+# Basic JWT
+
+This crate provide basic functions to:
+* Sign JWT
+* Parse and validate JWT
+
+
+Basic usage:
+
+```rust
+let claims = ...; // note : claims must be serializable
+
+// Generate a key pair. Public and private key are both serializable
+let (pub_key, priv_key) = generate_ec384_keypair().unwrap();
+
+// Create a JWT for the given claims (note: standard claims: sub, iss, ...) are not
+// automatically added if they are missing
+let jwt = sign_jwt(&priv_key, &claims).expect("Failed to sign JWT!");
+
+// Validate signed JWT
+let claims_out = validate_jwt::<Claims>(&pub_key, &jwt).expect("Failed to validate JWT!");
+```
