-## Cobra Client
+## Cobra client and server
 
-[cobra](https://github.com/machinezone/cobra) is a real time messenging server. ws has a sub-command to interact with cobra.
+[cobra](https://github.com/machinezone/cobra) is a real time messenging server. ws has several sub-command to interact with cobra. There is also a minimal cobra compatible server named snake available.
+
+Below are examples on running a snake server and clients with TLS enabled (the server only works with the OpenSSL and the Mbed TLS backend for now).
+
+First, generate certificates.
+
+```

+$ cd ixsnake/ixsnake
+$ bash ../../ws/generate_certs.sh

+
+Now run the snake server.
+
+```
+$ export certs=.certs
+$ ws snake --tls --port 8765 --cert-file ${certs}/trusted-server-crt.pem --key-file ${certs}/trusted-server-key.pem --ca-file ${certs}/trusted-ca-crt.pem

+      }
+    }
+  }
+}
+
+redis host: 127.0.0.1

+
+As a new connection comes in, such output should be printed

+
+To use OpenSSL on macOS, compile with `make ws_openssl`. First you will have to install OpenSSL libraries, which can be done with Homebrew. Use `make ws_mbedtls` accordingly to use MbedTLS.
