+### Optional: PQC ML-DSA Support
+
+To have ML-DSA support in wolfPKCS11, configure wolfSSL with ML-DSA (Dilithium)
+support enabled, either by adding `--enable-mldsa` to `./configure` or by
+setting `WOLFSSL_DILITHIUM` to `yes` in CMake.
+
+As ML-DSA is a feature of PKCS#11 version 3.2, support for that is required,
+too. Hence, to enable all in wolfPKCS11, add `--enable-pkcs11v32 --enable-mldsa`
+during the configure step.
