 micro-ecc
 ==========
 
-A small ECDH and ECDSA implementation for 8-bit, 32-bit, and 64-bit processors.
+A small and fast ECDH and ECDSA implementation for 8-bit, 32-bit, and 64-bit processors.
+
+The old version of micro-ecc can be found in the "old" branch.
 
 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.
+ * Written in C, with optional GCC inline assembly for AVR, ARM and Thumb platforms.
+ * Supports 8, 32, and 64-bit architectures.
+ * Small code size.
+ * No dynamic memory allocation.
+ * Support for 4 standard curves: secp160r1, secp192r1, secp256r1, and secp256k1.
  * BSD 2-clause license.
 
 Usage Notes
 -----------
+#### Point Representation ####
+Compressed points are represented in the standard format as defined in http://www.secg.org/collateral/sec1_final.pdf; uncompressed points are represented in standard format, but without the `0x04` prefix. `uECC_make_key()`, `uECC_shared_secret()`, `uECC_sign()`, and `uECC_verify()` only handle uncompressed points; you can use `uECC_compress()` and `uECC_decompress()` to convert between compressed and uncompressed point representations.
+
+Private keys are represented in the standard format.
+
 #### 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.

 #### Compilation Notes ####
 
+ * Should compile with any C/C++ compiler that supports stdint.h (this includes Visual Studio 2013).
  * 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 inline assembly enabled, you must have optimizations enabled (compile with `-O1` or higher).
+ * When building on Windows, you will need to link in the `advapi32.lib` system library.
