- * If you are: *\r
- * *\r
- * + New to FreeRTOS, *\r
- * + Wanting to learn FreeRTOS or multitasking in general quickly *\r
- * + Looking for basic training, *\r
- * + Wanting to improve your FreeRTOS skills and productivity *\r
- * *\r
- * then take a look at the FreeRTOS books - available as PDF or paperback *\r
- * *\r
- * "Using the FreeRTOS Real Time Kernel - a Practical Guide" *\r
- * http://www.FreeRTOS.org/Documentation *\r
- * *\r
- * A pdf reference manual is also available. Both are usually delivered *\r
- * to your inbox within 20 minutes to two hours when purchased between 8am *\r
- * and 8pm GMT (although please allow up to 24 hours in case of *\r
- * exceptional circumstances). Thank you for your support! *\r
