+## How to setup wolfSSL support for standard Zephyr TLS Sockets and RNG
+
+wolfSSL can also be used as the underlying implementation for the default Zephyr TLS socket interface.
+With this enabled, all existing applications using the Zephyr TLS sockets will now use wolfSSL inside
+for all TLS operations. This will also enable wolfSSL as the default RNG implementation. To enable this
+feature, first ensure wolfSSL has been added to the west manifest using the instructions from the
+README.md here: https://github.com/wolfSSL/wolfssl/tree/master/zephyr
+
+Once the west manifest has been updated, run west update, then run the following command to patch the sources
+
+```
+patch -p1 < /path/to/your/osp/zephyr/zephyr-tls-{PATCH_VERSION}.patch
+```
+
+Where PATCH_VERSION is the appropriate patch version.
+
+### Run Zephyr TLS samples
+
+```
+west build -b <your_board> samples/net/sockets/echo_server -DEXTRA_CONF_FILE=overlay-wolfssl.conf
+```
+
+### Run Zephyr TLS tests
+
+```
+west build -b <your_board> tests/net/socket/tls_ext/ -DEXTRA_CONF_FILE=overlay-wolfssl.conf
+```
+
+```
+west build -b <your_board> tests/net/socket/tls/ -DEXTRA_CONF_FILE=overlay-wolfssl.conf
+```
