 This example is a demonstration of how Mongoose Library could be integrated
 into an embedded device and provide a UART-to-Network bridge capability:
 
-- A device opens listening TCP port and Websocket port and waits for connections
+- The device opens listening TCP and Websocket ports and waits for connections
 - When a client connects, data is exchanged with the device's UART
-- Everything that client send, is sent to the UART
+- Everything the client sends, is sent to the UART
 - Everything that is read from the UART, gets sent to the client
 - Multiple clients are allowed
 - Live UART console allows to talk to the UART from the web page
 - Web UI is hardcoded into the binary and does not need a filesystem
