+The RippleAPI constructor optionally takes one argument, an object with the following options:
+
 Name | Type | Description
 ---- | ---- | -----------
 authorization | string | *Optional* Username and password for HTTP basic authentication to the rippled server in the format **username:password**.
+certificate | string | *Optional* A string containing the certificate key of the client in PEM format. (Can be an array of certificates).
 feeCushion | number | *Optional* Factor to multiply estimated fee by to provide a cushion in case the required fee rises during submission of a transaction. Defaults to `1.2`.
+key | string | *Optional* A string containing the private key of the client in PEM format. (Can be an array of keys).
+passphrase | string | *Optional* The passphrase for the private key of the client.
 proxy | uri string | *Optional* URI for HTTP/HTTPS proxy to use to connect to the rippled server.

 timeout | integer | *Optional* Timeout in milliseconds before considering a request to have failed.
 trace | boolean | *Optional* If true, log rippled requests and responses to stdout.
 trustedCertificates | array\<string\> | *Optional* Array of PEM-formatted SSL certificates to trust when connecting to a proxy. This is useful if you want to use a self-signed certificate on the proxy server. Note: Each element must contain a single certificate; concatenated certificates are not valid.
 
+If you omit the `server` parameter, RippleAPI operates [offline](#offline-functionality).

 ### Installation ###
 
 1. Install [NodeJS](https://nodejs.org) and the Node Package Manager (npm). Most Linux distros have a package for NodeJS, but make sure you have version `0.12.0` or higher.
 2. Use npm to install [Babel](https://babeljs.io/) globally:
-      `npm install -g babel`
+      `npm install -g babel-cli`
 3. Use npm to install RippleAPI:

+## Offline functionality
+
+RippleAPI can also function without internet connectivity. This can be useful in order to generate secrets and sign transactions from a secure, isolated machine.
+
+To instantiate RippleAPI in offline mode, use the following boilerplate code:
+
+```javascript
+const {RippleAPI} = require('ripple-lib');
+
+const api = new RippleAPI();
+/* insert code here */
+```
+
+Methods that depend on the state of the Ripple Consensus Ledger are unavailable in offline mode. To prepare transactions offline, you **must** specify  the `fee`, `sequence`, and `maxLedgerVersion` parameters in the [transaction instructions](#transaction-instructions). The following methods should work offline:
+
+* [preparePayment](#preparepayment)
+* [prepareTrustline](#preparetrustline)
+* [prepareOrder](#prepareorder)
+* [prepareOrderCancellation](#prepareordercancellation)
+* [prepareSettings](#preparesettings)

-The first parameter is a string indicating the error type, which may be `badMessage` (meaning that rippled returned a malformed message), or one of the [rippled Universal Errors](https://ripple.com/build/rippled-apis/#universal-errors). The second parameter is a message explaining the error, or the message that caused the error in the case of `badMessage`.
+The first parameter is a string indicating the error type:
+* `badMessage` - rippled returned a malformed message
+* `websocket` - the websocket library emitted an error
+* one of the error codes found in the [rippled Universal Errors](https://ripple.com/build/rippled-apis/#universal-errors).
+
+The second parameter is a message explaining the error.
+
+The third parameter is:
+* the message that caused the error for `badMessage`
+* the error object emitted for `websocket`
+* the parsed response for rippled errors
