 + `LastLedgerSequence` is set by default on outgoing transactions. This refers to the last valid ledger index (AKA sequence) for a transaction.

-##Getting Started
+## Getting Started
 
-Install `ripple-lib` using npm:
+See also: [RippleAPI Beginners Guide](https://ripple.com/build/rippleapi-beginners-guide/)
+
+You can use `npm`, but we recommend using `yarn` for the added assurance provided by `yarn.lock`.
+
++ [Yarn Installation Instructions](https://yarnpkg.com/en/docs/install)
+
+Install `ripple-lib`:
 ```
-  $ npm install ripple-lib
+$ yarn add ripple-lib
 ```
 
-Then see the sample code in `docs/samples`.
+Then see the [documentation](https://github.com/ripple/ripple-lib/blob/develop/docs/index.md) and [code samples](https://github.com/ripple/ripple-lib/tree/develop/docs/samples)
 
-##Running tests
+## Running tests
 
 1. Clone the repository
-2. `cd` into the repository and install dependencies with `npm install`
-3. `npm test` or `npm test --coverage` (`istanbul` will create coverage reports in coverage/lcov-report/`)
+2. `cd` into the repository and install dependencies with `yarn install`

-##More Information
+## Generating Documentation
 
-+ [Ripple Dev Portal](https://ripple.com/build/)
+The continuous integration tests require that the documentation stays up-to-date. If you make changes to the JSON schemas, fixtures, or documentation sources, you must update the documentation by running `yarn run docgen`.
+
+`npm` may be used instead of `yarn` in the commands above.

+# Basic Types
+
+## Address
+
+```json
+"r9cZA1mLK5R5Am25ArfXFmqgNwjZgnfk59"
+```
+
+Every XRP Ledger account has an *address*, which is a base58-encoding of a hash of the account's public key. XRP Ledger addresses always start with the lowercase letter `r`.
+
+## Account Sequence Number
+
+Every XRP Ledger account has a *sequence number* that is used to keep transactions in order. Every transaction must have a sequence number. A transaction can only be executed if it has the next sequence number in order, of the account sending it. This prevents one transaction from executing twice and transactions executing out of order. The sequence number starts at `1` and increments for each transaction that the account makes.
+
+## Currency
+
+Currencies are represented as either 3-character currency codes or 40-character uppercase hexadecimal strings. We recommend using uppercase [ISO 4217 Currency Codes](http://www.xe.com/iso4217.php) only. The string "XRP" is disallowed on trustlines because it is reserved for the XRP Ledger's native currency. The following characters are permitted: all uppercase and lowercase letters, digits, as well as the symbols `?`, `!`, `@`, `#`, `$`, `%`, `^`, `&`, `*`, `<`, `>`, `(`, `)`, `{`, `}`, `[`, `]`, and `|`.
+
+## Value
+A *value* is a quantity of a currency represented as a decimal string. Be careful: JavaScript's native number format does not have sufficient precision to represent all values. XRP has different precision from other currencies.
+
+**XRP** has 6 significant digits past the decimal point. In other words, XRP cannot be divided into positive values smaller than `0.000001` (1e-6). XRP has a maximum value of `100000000000` (1e11).
+
+**Non-XRP values** have 16 decimal digits of precision, with a maximum value of `9999999999999999e80`. The smallest positive non-XRP value is `1e-81`.
+
+
+## Amount
+
+Example amount:
+
+```json
+{
+  "currency": "USD",
+  "counterparty": "rMH4UxPrbuMa1spCBR98hLLyNJp4d8p4tM",
+  "value": "100"
+}
+```
+
+Example XRP amount:
+```json
+{
+  "currency": "XRP",
+  "value": "2000"
+}
+```
+
+An *amount* is data structure representing a currency, a quantity of that currency, and the counterparty on the trustline that holds the value. For XRP, there is no counterparty.
+
+A *lax amount* allows the counterparty to be omitted for all currencies. If the counterparty is not specified in an amount within a transaction specification, then any counterparty may be used for that amount.
+
+A *lax lax amount* allows either or both the counterparty and value to be omitted.
+
+A *balance* is an amount than can have a negative value.

+## Boilerplate
+
+Use the following [boilerplate code](https://en.wikipedia.org/wiki/Boilerplate_code) to wrap your custom code using RippleAPI.
+
+```javascript
+const RippleAPI = require('ripple-lib').RippleAPI;
+
+const api = new RippleAPI({
+  server: 'wss://s1.ripple.com' // Public rippled server hosted by Ripple, Inc.
+});
+api.on('error', (errorCode, errorMessage) => {
+  console.log(errorCode + ': ' + errorMessage);
+});
+api.on('connected', () => {
+  console.log('connected');
+});
+api.on('disconnected', (code) => {
+  // code - [close code](https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent) sent by the server
+  // will be 1000 if this was normal closure
+  console.log('disconnected, code:', code);
+});
+api.connect().then(() => {
+  /* insert code here */
+}).then(() => {
+  return api.disconnect();
+}).catch(console.error);
+```
+
+RippleAPI is designed to work in [Node.js](https://nodejs.org) version **6.11.3**. RippleAPI may work on older Node.js versions if you use [Babel](https://babeljs.io/) for [ECMAScript 6](https://babeljs.io/docs/learn-es2015/) support.
+
+The code samples in this documentation are written with ECMAScript 6 (ES6) features, but `RippleAPI` also works with ECMAScript 5 (ES5). Regardless of whether you use ES5 or ES6, the methods that return Promises return [ES6-style promises](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+
+<aside class="notice">
+All the code snippets in this documentation assume that you have surrounded them with this boilerplate.
+</aside>
+
+<aside class="notice">
+If you omit the "catch" section, errors may not be visible.
+</aside>
+
+<aside class="notice">
+The "error" event is emitted whenever an error occurs that cannot be associated with a specific request. If the listener is not registered, an exception will be thrown whenever the event is emitted.
+</aside>
+
+### Parameters
+
+The RippleAPI constructor optionally takes one argument, an object with the following options:
+
+<%- renderSchema('input/api-options.json') %>
+
+If you omit the `server` parameter, RippleAPI operates [offline](#offline-functionality).
+
+
+### Installation ###
+
+1. Install [Node.js](https://nodejs.org) and [Yarn](https://yarnpkg.com/en/docs/install). Most Linux distros have a package for Node.js; check that it's the version you want.
+2. Use yarn to install RippleAPI:
+      `yarn install ripple-lib`
+
+After you have installed ripple-lib, you can create scripts using the [boilerplate](#boilerplate) and run them using the Node.js executable, typically named `node`:
+
+      `node script.js`

+# Introduction
+
+RippleAPI is the official client library to the XRP Ledger. Currently, RippleAPI is only available in JavaScript.
+Using RippleAPI, you can:
+
+* [Query transactions from the XRP Ledger history](#gettransaction)
+* [Sign](#sign) transactions securely without connecting to any server
+* [Submit](#submit) transactions to the XRP Ledger, including [Payments](#payment), [Orders](#order), [Settings changes](#settings), and [other types](#transaction-types)
+* [Generate a new XRP Ledger Address](#generateaddress)
+* ... and [much more](#api-methods).
+
+RippleAPI only provides access to *validated*, *immutable* transaction data.

+
+### Parameters
+
+This method has no parameters.
+
+### Return Value
+

+## 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').RippleAPI;
+
+const api = new RippleAPI();
+/* insert code here */
+```
+
+Methods that depend on the state of the XRP 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). You can use the following methods while offline:
+
+* [preparePayment](#preparepayment)
+* [prepareTrustline](#preparetrustline)
+* [prepareOrder](#prepareorder)
+* [prepareOrderCancellation](#prepareordercancellation)
+* [prepareSettings](#preparesettings)
+* [prepareEscrowCreation](#prepareescrowcreation)
+* [prepareEscrowCancellation](#prepareescrowcancellation)
+* [prepareEscrowExecution](#prepareescrowexecution)
+* [sign](#sign)
+* [generateAddress](#generateaddress)

+# Transaction Overview
+
+## Transaction Types
+
+A transaction type is specified by the strings in the first column in the table below.
+
+Type | Description
+---- | -----------
+[payment](#payment) | A `payment` transaction represents a transfer of value from one account to another. Depending on the [path](https://ripple.com/build/paths/) taken, additional exchanges of value may occur atomically to facilitate the payment.
+[order](#order) | An `order` transaction creates a limit order. It defines an intent to exchange currencies, and creates an order in the XRP Ledger's order book if not completely fulfilled when placed. Orders can be partially fulfilled.
+[orderCancellation](#order-cancellation) | An `orderCancellation` transaction cancels an order in the XRP Ledger's order book.
+[trustline](#trustline) | A `trustline` transactions creates or modifies a trust line between two accounts.
+[settings](#settings) | A `settings` transaction modifies the settings of an account in the XRP Ledger.
+[escrowCreation](#escrow-creation) | An `escrowCreation` transaction creates an escrow on the ledger, which locks XRP until a cryptographic condition is met or it expires. It is like an escrow service where the XRP Ledger acts as the escrow agent.
+[escrowCancellation](#escrow-cancellation) | An `escrowCancellation` transaction unlocks the funds in an escrow and sends them back to the creator of the escrow, but it will only work after the escrow expires.
+[escrowExecution](#escrow-execution) | An `escrowExecution` transaction unlocks the funds in an escrow and sends them to the destination of the escrow, but it will only work if the cryptographic condition is provided.
+[checkCreate](#check-create) | A `checkCreate` transaction creates a check on the ledger, which is a deferred payment that can be cashed by its intended destination.
+[checkCancel](#check-cancel) | A `checkCancel` transaction cancels an unreedemed Check, removing it from the ledger without sending any money.
+[checkCash](#checkCash) | A `checkCash` transaction redeems a Check to receive up to the amount authorized by the corresponding `checkCreate` transaction. Only the `destination` address of a Check can cash it.
+
+## Transaction Flow
+
+Executing a transaction with `RippleAPI` requires the following four steps:
+
+1. Prepare - Create an unsigned transaction based on a [specification](#transaction-specifications) and [instructions](#transaction-instructions). There is a method to prepare each type of transaction:
+    * [preparePayment](#preparepayment)
+    * [prepareTrustline](#preparetrustline)
+    * [prepareOrder](#prepareorder)
+    * [prepareOrderCancellation](#prepareordercancellation)
+    * [prepareSettings](#preparesettings)
+    * [prepareEscrowCreation](#prepareescrowcreation)
+    * [prepareEscrowCancellation](#prepareescrowcancellation)
+    * [prepareEscrowExecution](#prepareescrowexecution)
+    * [prepareCheckCreate](#preparecheckcreate)
+    * [prepareCheckCancel](#preparecheckcancel)
+    * [prepareCheckCash](#preparecheckcash)
+2. [Sign](#sign) - Cryptographically sign the transaction locally and save the [transaction ID](#transaction-id). Signing is how the owner of an account authorizes a transaction to take place. For multisignature transactions, the `signedTransaction` fields returned by `sign` must be collected and passed to the [combine](#combine) method.
+3. [Submit](#submit) - Submit the transaction to the connected server.
+4. Verify - Verify that the transaction got validated by querying with [getTransaction](#gettransaction). This is necessary because transactions may fail even if they were successfully submitted.
+
+## Transaction Fees
+
+Every transaction must destroy a small amount of XRP as a cost to send the transaction. This is also called a *transaction fee*. The transaction cost is designed to increase along with the load on the XRP Ledger, making it very expensive to deliberately or inadvertently overload the peer-to-peer network that powers the XRP Ledger.
+
+You can choose the size of the fee you want to pay or let a default be used. You can get an estimate of the fee required to be included in the next ledger closing with the [getFee](#getfee) method.
+
+## Transaction Instructions
+
+Transaction instructions indicate how to execute a transaction, complementary with the [transaction specification](#transaction-specifications).
+
+<%- renderSchema("objects/instructions.json") %>
+
+We recommended that you specify a `maxLedgerVersion` so that you can quickly determine that a failed transaction will never succeeed in the future. It is impossible for a transaction to succeed after the XRP Ledger's consensus-validated ledger version exceeds the transaction's `maxLedgerVersion`. If you omit `maxLedgerVersion`, the "prepare*" method automatically supplies a `maxLedgerVersion` equal to the current ledger plus 3, which it includes in the return value from the "prepare*" method.
+
+## Transaction ID
+
+```json
+"F4AB442A6D4CBB935D66E1DA7309A5FC71C7143ED4049053EC14E3875B0CF9BF"
+```
+
+A transaction ID is a 64-bit hexadecimal string that uniquely identifies the transaction. The transaction ID is derived from the transaction instruction and specifications, using a strong hash function.
+
+You can look up a transaction by ID using the [getTransaction](#gettransaction) method.
+
+## Transaction Memos
+
+Every transaction can optionally have an array of memos for user applications. The `memos` field in each [transaction specification](#transaction-specifications) is an array of objects with the following structure:
