To build a btc-lib full bundle for the browser:

gulp browser

This will generate files named btc-lib.js and btc-lib.min.js.

git clone https://github.com/owstack/btc-lib
cd btc-lib
npm install

Run all the tests:

gulp test

You can also run just the Node.js tests with gulp test:node, just the browser tests with gulp test:browser or create a test coverage report (you can open coverage/lcov-report/index.html to visualize it) with gulp coverage.
