-## 50 IR protocols supported and low memory footprint
-- Only 39 protocols can be enabled for receive at the same time, because some of them are quite similar and conflicts with each other.

+# Features
+- Total of 50 IR protocols supported.
+- Up to 39 protocols can be enabled for receive at the same time, because some of the 50 protocols are quite similar and conflicts with each other.
 - 39 protocols are available for send.
-- FLASH usage in bytes: 1500 for one protocol, 4300 for 15 main and 8000 for all 39 protocols.
+- Low memory footprint. FLASH usage in bytes: 1500 for one protocol, 4300 for 15 main and 8000 for all 39 protocols.
 - RAM usage in bytes: 52, 73 and 100.
