 A simple wrapper module for `ethjs-provider-http` which allows you to sign sendTransaction payloads. It simply takes the sendTransaction data, signs it, and changes the payload method from `eth_sendTransaction` to `eth_sendRawTransaction`, then sends the payload.
 
-The `privateKey` method is called everytime a payload must be signed. It provides the account address in question. The return should be a single privateKey string.
+The `signTransaction` method is called everytime a payload must be signed. It provides the raw transaction data, a handy raw transaction signing method and a callback to be fired. The callback must return a single signed alphanumeric hex data payload of the signed raw transaction.
+
+The optionally required signing method `SignerProvider.sign` will sign the raw transaction with your specified private key.
+
+The provided `SignerProvider.sign` method intakes the `rawTx` transaction data and the `privateKey` hex for signing. It returns the hexified string data of the signed transaction.

+Note, the `./lib` dir is generated from the babel build staging. `./coverage` is generated from the `npm run test-travis` script. All internals and helper scripts (i.e. `webpack`) are in `./internals`. All distribution builds are in `./dist` (usually a minified and unminified production build of the package).
 
 ## NPM Practice
 
 Across all `ethjs-` repos, we enforce version hardening (i.e. "0.0.3" not "^0.0.3"). We want to reduce potential hazardous install changes from dependancies as much as possible to ensure package preformace, testing, security and design. Please make sure all your commits and PR's are version hardend if you are installing or removing new packages.

+## Browser Builds
+
+`ethjs` provides production distributions for all of its modules that are ready for use in the browser right away. Simply include either `dist/ethjs-provider-signer.js` or `dist/ethjs-provider-signer.min.js` directly into an HTML file to start using this module. Note, an `SignerProvider` object is made available globally.
+
+```html
+<script type="text/javascript" src="ethjs-provider-signer.min.js"></script>
+<script type="text/javascript">
+new SignerProvider(...);
+</script>
+```
+
+Note, even though `ethjs` should have transformed and polyfilled most of the requirements to run this module across most modern browsers. You may want to look at an additional polyfill for extra support.
+
+Use a polyfill service such as `Polyfill.io` to ensure complete cross-browser support:
