+## About
 jsSHA is a javaScript implementation of the complete Secure Hash Algorithm
 family as defined by FIPS PUB 180-2
 (http://csrc.nist.gov/publications/fips/fips180-2/fips180-2withchangenotice.pdf).

 on 25 February 2004 so it was also included in this package.

+
+	npm install jsSHA
+To use the module, first require it using:

+	jsSHA = require("jsSHA");

+The rest of the instructions are identical to the [Browser](#browser) section above.

+## Compiling
 This library makes use of the Google Closure Compiler
 (https://developers.google.com/closure/compiler) to both boost performance
 and reduce filesizes.  To compile sha_dev.js into a customized output file, use
 a command like the following:
 
-	java -jar compiler.jar --define="SUPPORTED_ALGS=<FLAG>"
-		--output_wrapper "(function() {%output%})();" --warning_level VERBOSE
-		--compilation_level ADVANCED_OPTIMIZATIONS --js sha_dev.js --js_output_file sha.js
+	java -jar compiler.jar --define="SUPPORTED_ALGS=<FLAG>" \
+		--externs /path/to/build/externs.js --warning_level VERBOSE \
+		--compilation_level ADVANCED_OPTIMIZATIONS \
+		--js /path/to/sha_dev.js --js_output_file /path/to/sha.js
 		
 where <FLAG> is a bitwise OR of the following values:
   - 4 for SHA-384/SHA-512
   - 2 for SHA-224/256
   - 1 for SHA-1
