 As outlined above, an OpenPGP signature is a composite data structure, which combines:
 
-- A *signature type ID* (see above), which specifies the intended meaning of the signature,
-- Metadata (which is variable and depends in part on the type ID),
-  - Most of this metadata is encoded as so-called "subpackets," see {ref}`signature_subpackets`,
-- A raw cryptographic signature.
+- **Signature type ID**: specifies the signature's intended meaning, as detailed above
+- **Metadata**: varies based, in part, on the signature type ID; mostly encoded as "subpackets" (see {ref}`signature_subpackets`)
+- **Raw cryptographic signature**
