+## About
+
+Verifiable credentials issuing and verification for IC canisters.
+
+Issuers can use this library to issue credentials and verify the id alias credential received from the identity provider.
+
+Relying parties can use this library to verify the credentials received.
+
+More information about [Verifiable Credentials in the Internet Computer documentation](https://internetcomputer.org/docs/current/developer-docs/identity/verifiable-credentials/overview).
+
+## Getting Started
+
+### Installation
+
+Install with cargo:
+
+```shell
+cargo add ic-verifiable-credentials
+```
+
+Or add it to your `Cargo.toml`.
+
+```toml
+ic-verifiable-credentials = "1.0.0"
+```
+
+### Usage
+
+Main functions for issuers:
+
+- `build_credential_jwt`. Builds a verifiable credential with the given parameters and returns the credential as a JWT-string.
+- `did_for_principal`. Returns a DID for the given `principal`.
+- `vc_jwt_to_jws`. Constructs and returns a JWS (a signed JWT) from the given components.
+- `vc_signing_input`. Returns the effective bytes that will be signed when computing a canister signature for the given JWT-credential, verifiable via the specified public key.
+- `vc_signing_input_hash`. Computes and returns SHA-256 hash of the given `signing_input`.
+- `get_verified_id_alias_from_jws`. Verifies the given JWS-credential as an id_alias-VC and extracts the alias tuple.
+
+Main function for relying parties:
+
+- `validate_ii_presentation_and_claims`. Validates the provided presentation `vp_jwt`, both cryptographically and semantically.
