+wolfSSH now supports the post-quantum algorithm ML-KEM (formerly known as Kyber).
+It uses the ML-KEM-512 parameter set and is hybridized with ECDHE over the P-256
 ECC curve.
 
 In order to use this key exchange you must build and install wolfSSL on your
 system. Here is an example of an effective configuration:
 
-    $ ./configure --enable-wolfssh --enable-experimental --enable-kyber
+    $ ./configure --enable-wolfssh --enable-experimental --enable-mlkem
 
 After that, simply configure and build wolfssh as usual:
 
     $ ./configure
     $ make all
