-avr-ecc
-=======
+micro-ecc
+==========
 
-Simple ECC library for AVR microcontrollers.
+A small ECDH and ECDSA implementation for 8-bit, 32-bit, and 64-bit processors.
+
+Features
+--------
+
+ * Resistant to known side-channel attacks.
+ * Written in C, with optional inline assembly for AVR, ARM and Thumb platforms.
+ * Support for 3 standard curves: secp160r1, secp192r1, and secp256r1.
+ * BSD 2-clause license.
+
+Usage Notes
+-----------
+#### Using the Code ####
+
+I recommend just copying (or symlink) uECC.h and uECC.c into your project. Then just `#include "uECC.h"` to use the micro-ecc functions.
+
+See uECC.h for documentation for each function.
+
+#### Compilation Notes ####
+
+ * When compiling for a Thumb-1 platform with inline assembly enabled (ie, `uECC_ASM` is defined to `uECC_asm_small` or `uECC_asm_fast`), you must use the `-fomit-frame-pointer` GCC option (this is enabled by default when compiling with `-O1` or higher).
+ * When compiling for AVR with `uECC_ASM` defined to `uECC_asm_fast`, you must have optimizations enabled (compile with `-O1` or higher).
