+Interrupt driven UART library using the built-in UART with circular transmit and receive buffers.
 
 An interrupt is generated when the UART has finished transmitting or
 receiving a byte. The interrupt handling routines use circular buffers
 for buffering received and transmitted data.
 
 ## Setting up
 
-The `UART_RXn_BUFFER_SIZE` and `UART_TXn_BUFFER_SIZE` constants define
-the size of the circular buffers in bytes. Note that these constants must be a power of 2.
-You may need to adapt this constants to your target and your application by adding to your
-compiler options:

+You may need to adapt this symbols to your target and your application by adding into your compiler options:
 
 	-DUART_RXn_BUFFER_SIZE=nn -DUART_TXn_BUFFER_SIZE=nn
