+Here we again go through the steps of creating an `eddsa-rdfc-2022` signed
+credential but with a more complicated input document. The
+representation of the public key and the representation of the private key
+are shown below.
+        </p>
+        <pre class="example nohighlight" title="Private and Public keys for Signature">

+}
+        </pre>
+
+        <p>
+Signing begins with a credential without an attached proof, which is converted
+to canonical form, and then hashed, as shown in the following three examples.
+        </p>

+
+        <p>
+The next step is to take the proof options document, convert it to canonical
+form, and obtain its hash, as shown in the next three examples.
+        </p>
+
+        <pre class="example nohighlight" title="Proof Options Document"

+
+        <p>
+Finally, we concatenate the hash of the proof options followed by the hash of
+the credential without proof, use the private key with the combined hash to
+compute the Ed25519 signature, and then base58-btc encode the signature.
