-To setup the required PQM4 source files, please run the `setup_kyber.sh` script
-in this directory. It will clone releveant git repos from github and generate
-the directories and files you need.
+Detailed instructions on how to build a project with wolfssl can be found at:
+
+https://github.com/wolfSSL/wolfssl/tree/master/IDE/STM32Cube
+
+1. Follow instructions at the link above and make sure you can perform "Example
+   for TLS v1.3 over UART".
+2. Run the `setup_kyber.sh` script in this directory. It will clone relevant
+   git repos from github and generate the directories and files you need.
+3. Drag and drop the include files into `Inc` and the `pqm4_kyber512` directory
+   into `Core`.
+4. Turn on the PQM4 integration.
+   - Open the .ioc file
+   - Click "Software Packs"
+   - Click on the wolfSSL.I-CUBE-wolfSSL.<version> that appears.
+   - In the Configuration box that appears, set "PQM4 Post-Quantum Integration
+     Support" to "True"
+   - Close the .ioc file and generate code.
+   - Build your project.
+
+For your reference, `wolfssl_stm32_pq` is a minimal starting project that has
+many things already configured. If you have a NUCLEO-F446ZE evaluation board
+Then you can skip step 1 and 4 and just use that.
 
 Once you have successfully built and flashed the project, the STM32 terminal
