+compile 'com.yubico:webauthn-server-core:1.0.0-RC2'
+----------
+
+
+== Features
+
+- Generates request objects suitable as parameters to
+  `navigator.credentials.create()` and `.get()`
+- Performs all necessary
+  https://www.w3.org/TR/webauthn/#rp-operations[validation logic] on the
+  response from the client
+- Optionally integrates with a "metadata service" to verify
+  https://www.w3.org/TR/webauthn/#sctn-attestation[authenticator attestations]
+  and annotate responses with additional authenticator metadata
+
+
+=== Non-features
+
+This library has no concept of accounts, sessions, permissions or identity
+federation, and it's not an authentication framework; it only deals with
+executing the WebAuthn authentication mechanism. Sessions, account management
+and other higher level concepts can make use of this authentication mechanism,
+but the authentication mechanism alone does not make a security system.
+
+
+== Documentation
+
+See the
+link:https://yubico.github.io/java-webauthn-server/webauthn-server-core/com/yubico/webauthn/package-summary.html[Javadoc]

+== Quick start
+
+Implement the
+link:https://yubico.github.io/java-webauthn-server/webauthn-server-core/com/yubico/webauthn/CredentialRepository.html[`CredentialRepository`]
+interface with your database access logic. See
+link:https://github.com/Yubico/java-webauthn-server/blob/master/webauthn-server-demo/src/main/java/demo/webauthn/InMemoryRegistrationStorage.java[`InMemoryRegistrationStorage`]
+for an example.
+
+Instantiate the
+link:https://yubico.github.io/java-webauthn-server/webauthn-server-core/com/yubico/webauthn/RelyingParty.html[`RelyingParty`]
+class:
+
+[source,java]
+----------
+RelyingPartyIdentity rpIdentity = RelyingPartyIdentity.builder()
+    .id("example.com")
+    .name("Example Application")
+    .build();
+
+RelyingParty rp = RelyingParty.builder()
+    .identity(rpIdentity)
+    .credentialRepository(new MyCredentialRepository())
+    .build();
+----------
+
+
+=== Registration
+
+Initiate a registration ceremony:
+
+[source,java]
+----------
+byte[] userHandle = new byte[64];
+random.nextBytes(userHandle);
+
+PublicKeyCredentialCreationOptions request = rp.startRegistration(StartRegistrationOptions.builder()
+    .user(UserIdentity.builder()
+        .name("alice")
+        .displayName("Alice Hypothetical")
+        .id(new ByteArray(userHandle))
+        .build())
+    .build());
+----------
+
+Serialize `request` to JSON and send it to the client:
+
+[source,java]
+----------
+import com.fasterxml.jackson.databind.ObjectMapper;
+
+ObjectMapper jsonMapper = new ObjectMapper()
+    .configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false)
+    .setSerializationInclusion(Include.NON_ABSENT)
+    .registerModule(new Jdk8Module());
+
+String json = jsonMapper.writeValueAsString(request);
+return json;
+----------
+
+Get the response from the client:
+
+[source,java]
+----------
+String responseJson = /* ... */;
+PublicKeyCredential<AuthenticatorAttestationResponse, ClientRegistrationExtensionOutputs> pkc =
+    jsonMapper.readValue(responseJson, new TypeReference<PublicKeyCredential<AuthenticatorAttestationResponse, ClientRegistrationExtensionOutputs>>(){});
+----------
+
+Validate the response:
+
+[source,java]
+----------
+try {
+    RegistrationResult result = rp.finishRegistration(FinishRegistrationOptions.builder()
+        .request(request)
+        .response(pkc)
+        .build());
+} catch (RegistrationFailedException e) { /* ... */ }
+----------
+
+Update your database:
+
+[source,java]
+----------
+storeCredential("alice", result.getKeyId(), result.getPublicKeyCose());
+----------
+
+
+=== Authentication
+
+Initiate an authentication ceremony:
+
+
+[source,java]
+----------
+AssertionRequest request = rp.startAssertion(StartAssertionOptions.builder()
+    .username(Optional.of("alice"))
+    .build());
+String json = jsonMapper.writeValueAsString(request);
+return json;
+----------
+
+Validate the response:
+
+[source,java]
+----------
+String responseJson = /* ... */;
+
+PublicKeyCredential<AuthenticatorAssertionResponse, ClientAssertionExtensionOutputs> pkc =
+    jsonMapper.readValue(responseJson, new TypeReference<PublicKeyCredential<AuthenticatorAssertionResponse, ClientAssertionExtensionOutputs>>() {
+});
+
+try {
+    AssertionResult result = rp.finishAssertion(FinishAssertionOptions.builder()
+        .request(request)
+        .response(pkc)
+        .build());
+
+    if (result.isSuccess()) {
+        return result.getUsername();
+    }
+} catch (AssertionFailedException e) { /* ... */ }
+throw new RuntimeException("Authentication failed");

+
+
+== Architecture
+
+The library tries to place as few requirements on the overall application
+architecture as possible. For this reason it is stateless and free from side
+effects, and does not directly interact with any database. This means it is
+database agnostic and thread safe. The following diagram illustrates an example
+architecture for an application using the library.
+
+image::https://raw.githubusercontent.com/Yubico/java-webauthn-server/master/docs/img/demo-architecture.svg["Example application architecture",align="center"]
+
+The application manages all state and database access, and communicates with the
+library via POJO representations of requests and responses. The following
+diagram illustrates the data flow during a WebAuthn registration or
+authentication ceremony.
+
+image::https://raw.githubusercontent.com/Yubico/java-webauthn-server/master/docs/img/demo-sequence-diagram.svg["WebAuthn ceremony sequence diagram",align="center"]
+
+In this diagram, the *Client* is the user's browser and the application's
+client-side scripts. The *Server* is the application and its business logic, the
+*Library* is this library, and the *Users* database stores registered WebAuthn
+credentials.
+
+. The client requests to start the ceremony, for example by submitting a form.
+  The `username` may or may not be known at this point. For example, the user
+  might be requesting to create a new account, or we might be using
+  username-less authentication.
+
+. If the user does not already have a
+  https://www.w3.org/TR/webauthn/#user-handle[user handle], the application
+  creates one in some application-specific way.
+
+. The application may choose to authenticate the user with a password or the
+  like before proceeding.
+
+. The application calls one of the library's "start" methods to generate a
+  parameter object to be passed to `navigator.credentials.create()` or `.get()`
+  on the client.
+
+. The library generates a random challenge and an assortment of other arguments
+  depending on configuration set by the application.
+
+. If the `username` is known, the library uses a read-only database adapter
+  provided by the application to look up the user's credentials.
+
+. The returned list of https://www.w3.org/TR/webauthn/#credential-id[credential
+  IDs] is used to populate the
+  https://www.w3.org/TR/webauthn/#dom-publickeycredentialcreationoptions-excludecredentials[`excludeCredentials`]
+  or
+  https://www.w3.org/TR/webauthn/#dom-publickeycredentialrequestoptions-allowcredentials[`allowCredentials`]
+  parameter.
+
+. The library returns a `request` object which can be serialized to JSON and
+  passed as the `publicKey` argument to `navigator.credentials.create()` or
+  `.get()`. For registration ceremonies this will be a
+  https://www.w3.org/TR/webauthn/#dictdef-publickeycredentialcreationoptions[`PublicKeyCredentialCreationOptions`],
+  and for authentication ceremonies it will be a
+  https://www.w3.org/TR/webauthn/#dictdef-publickeycredentialrequestoptions[`PublicKeyCredentialRequestOptions`].
+  The application stores the `request` in temporary storage.
+
+. The application's client-side script runs `navigator.credentials.create()` or
+  `.get()` with `response` as the `publicKey` argument.
+
+. The user confirms the operation and the client returns a
+  https://www.w3.org/TR/webauthn/#public-key-credential[`PublicKeyCredential`]
+  object `response` to the application.
+
+. The application retrieves the `request` from temporary storage and passes
+  `request` and `response` to one of the library's "finish" methods to run the
+  response validation logic.
+
+. The library verifies that the `response` contents - challenge, origin, etc. -
+  are valid.
+
+. If this is an authentication ceremony, the library uses the database adapter
+  to look up the public key for the credential named in `response.id`.
+
+. The database adapter returns the public key.
+
+. The library verifies the authentication signature.
+
+. The library returns a POJO representation of the result of the ceremony. For
+  registration ceremonies, this will include the credential ID and public key of
+  the new credential. The application may also opt in to also getting
+  information about the authenticator model and whether the authenticator
+  attestation is trusted. For authentication ceremonies, this will include the
+  username and user handle, the credential ID of the credential used, and the
+  new https://www.w3.org/TR/webauthn/#signature-counter[signature counter] value
+  for the credential.
+
+. The application inspects the result object and takes any appropriate actions
+  as defined by its business logic.
 
-None.
+. If the result is not satisfactory, the application reports failure to the
+  client.
 
+. If the result is satisfactory, the application proceeds with storing the new
+  credential if this is a registration ceremony.
 
-=== Example Usage
+. If this is an authentication ceremony, the application updates the signature
+  counter stored in the database for the credential.
 
-See link:webauthn-server-demo[`webauthn-server-demo`] for a complete demo
-server, which stores authenticator registrations temporarily in memory.
+. Finally, the application reports success and resumes its business logic.
