 ## About
 
-TrustVC is a comprehensive wrapper library designed to simplify the signing and verification processes for TrustVC W3C [Verifiable Credentials (VC)](https://github.com/TrustVC/w3c) and OpenAttestation Verifiable Documents (VD), adhering to the W3C [VC](https://www.w3.org/TR/vc-data-model/) Data Model v2.0 (W3C Standard). It ensures compatibility and interoperability for Verifiable Credentials while supporting OpenAttestation [Verifiable Documents (VD)](https://github.com/Open-Attestation/open-attestation) v6.9.5. TrustVC seamlessly integrates functionalities for handling W3C Verifiable Credentials and OpenAttestation Verifiable Documents, leveraging existing TradeTrust libraries and smart contracts for [Token Registry](https://github.com/TradeTrust/token-registry) (V4 and V5). Additionally, it includes essential utility functions for strings, networks, and chains, making it a versatile tool for developers working with decentralized identity and verifiable data solutions.

 ### 4. **Verifying**
 
-> TrustVC simplifies the verification process with a single function that supports both W3C Verifiable Credentials (VCs) and OpenAttestation Verifiable Documents (VDs). Whether you're working with W3C standards or OpenAttestation standards, TrustVC handles the verification seamlessly. For ECDSA-SD-2023 and BBS-2023 signed documents, which normally require derivation before verification, TrustVC automatically handles this process internally - if a document is not derived, the `verifyDocument` function will automatically derive and verify the document in a single step.
