 The following section will delve into the OpenPGP-specific layers (2 and 3) to provide a clearer understanding of their roles within OpenPGP certificates.
 
-For a discussion of private key material in OpenPGP, see the chapter {ref}`private_key_chapter`. Bindings that connect the components of a certificate are discussed in our chapter {ref}`component_signatures_chapter`. For much more detail on the internal (packet) structure of certificates and keys refer to our chapter {ref}`zoom_certificates`. Additionally, managing certificates, and understanding their authentication and trust models are vital topics. While this document only touches upon these aspects briefly, they are integral to working proficiently with OpenPGP.
+Fundamentally, the effective management of certificates and a thorough grasp of their authentication and trust models are crucial for proficient OpenPGP usage. Although this document offers just a brief overview of these aspects, they form a fundamental part of the broader OpenPGP framework and warrant further study.
