 .. note:: If you want to verify the server, then you need to provide a certificate in PEM format, and provide to ``cert_pem`` in :cpp:type:`websocket_client_config_t`. If no certficate is provided then the TLS connection will default to not requiring verification.
 
 PEM certificate for this example could be extracted from an openssl `s_client` command connecting to websocket.org.
-In case a host operating system has `openssl` and `sed` packages installed, one could execute the following command to download and save the root or intermediate root certificate to a file (Note for Windows users: Both Linux like environment or Windows native packages may be used).

 Events
 ------
-* `WEBSOCKET_EVENT_BEGIN': The client thread is running.
+* `WEBSOCKET_EVENT_BEGIN`: The client thread is running.
 * `WEBSOCKET_EVENT_BEFORE_CONNECT`: The client is about to connect.
 * `WEBSOCKET_EVENT_CONNECTED`: The client has successfully established a connection to the server. The client is now ready to send and receive data. Contains no event data.
 * `WEBSOCKET_EVENT_DATA`: The client has successfully received and parsed a WebSocket frame. The event data contains a pointer to the payload data, the length of the payload data as well as the opcode of the received frame. A message may be fragmented into multiple events if the length exceeds the buffer size. This event will also be posted for non-payload frames, e.g. pong or connection close frames.
 * `WEBSOCKET_EVENT_ERROR`: The client has experienced an error. Examples include transport write or read failures.
 * `WEBSOCKET_EVENT_DISCONNECTED`: The client has aborted the connection due to the transport layer failing to read data, e.g. because the server is unavailable. Contains no event data.
 * `WEBSOCKET_EVENT_CLOSED`: The connection has been closed cleanly.
-* `WEBSOCKET_EVENT_FINISH': The client thread is about to exit.
+* `WEBSOCKET_EVENT_FINISH`: The client thread is about to exit.
 
 If the client handle is needed in the event handler it can be accessed through the pointer passed to the event handler:
