+# Basic Types
+
+## Ripple Address
+
+```json
+"r9cZA1mLK5R5Am25ArfXFmqgNwjZgnfk59"
+```
+
+Every Ripple account has an *address*, which is a base58-encoding of a hash of the account's public key. Ripple addresses always start with the lowercase letter `r`.
+
+## Account Sequence Number
+
+Every Ripple 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 Ripple 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).

+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');
+
+const api = new RippleAPI({
+  server: 'wss://s1.ripple.com' // Public rippled server hosted by Ripple, Inc.
+});
+api.connect().then(() => {
+  /* insert code here */
+}).then(() => {
+  return api.disconnect();
+}).catch(console.error);
+```
+
+RippleAPI is designed to work in [NodeJS](https://nodejs.org) (version `0.12.0` or greater) using [Babel](https://babeljs.io/) for [ECMAScript 6](https://babeljs.io/docs/learn-es2015/) support.
+
+The code samples in this documentation are written in ES6, but `RippleAPI` will work with ES5 also. Regardless of whether you use ES5 or ES6, the methods that return promises will 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>
+
+### 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 [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`
+3. Use npm to install RippleAPI:
+      `npm install ripple-lib`
+
+After you have installed ripple-lib, you can create scripts using the [boilerplate](#boilerplate) and run them using babel-node:
+      `babel-node script.js`
+
+<aside class="notice">
+Instead of using babel-node in production, we recommend using Babel to transpile to ECMAScript 5 first.

+* [Sign](#sign) transactions securely without connecting to any server
+* [Submit](#submit) transactions to the Ripple Consensus Ledger, including [Payments](#payment), [Orders](#order), [Settings changes](#settings), and [other types](#transaction-types)
+* [Generate a new Ripple Address](#generateaddress)
+* ... and [much more](#api-methods).

+## 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:

+# 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 Ripple Consensus 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 Ripple Consensus 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 Ripple Consensus Ledger.
+[suspendedPaymentCreation](#suspended-payment-creation) | A `suspendedPaymentCreation` transaction creates a suspended payment on the ledger, which locks XRP until a cryptographic condition is met or it expires. It is like an escrow service where the Ripple network acts as the escrow agent.
+[suspendedPaymentCancellation](#suspended-payment-cancellation) | A `suspendedPaymentCancellation` transaction unlocks the funds in a suspended payment and sends them back to the creator of the suspended payment, but it will only work after the suspended payment expires.
+[suspendedPaymentExecution](#suspended-payment-execution) | A `suspendedPaymentExecution` transaction unlocks the funds in a suspended payment and sends them to the destination of the suspended payment, but it will only work if the cryptographic condition is provided.
+
+The three "suspended payment" transaction types are not supported by the production Ripple peer-to-peer network at this time. They are available for testing purposes if you [configure RippleAPI](#boilerplate) to connect to the [Ripple Test Net](https://ripple.com/build/ripple-test-net/) instead.
+
+## 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)
+    * [prepareSuspendedPaymentCreation](#preparesuspendedpaymentcreation)
+    * [prepareSuspendedPaymentCancellation](#preparesuspendedpaymentcancellation)
+    * [prepareSuspendedPaymentExecution](#preparesuspendedpaymentexecution)
+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.
+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 Ripple network, making it very expensive to deliberately or inadvertently overload the network.
+
+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 network 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:
+
+<%- renderSchema('objects/memos.json') %>
