+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 order transactions. Every transaction must have a sequence number and transaction can only be executed in order by sequence number. 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.
+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).
+
+**Non-XRP values** have 16 decimal digits of precision, with a maximum value of `9999999999999999e80`. The smallest positive non-XRP value is `1e-81`.

 # Introduction
 
-RippleAPI allows you to query and submit transactions to a node on the Ripple network.
+RippleAPI is the official client library to the Ripple Consensus Ledger. Currently, RippleAPI is only available in JavaScript. 
+Using RippleAPI, you can:
+
+* [Query transactions from the network](#gettransaction)
+* [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).
 
 RippleAPI only provides access to *validated*, *immutable* transaction data.

docs/src/offline.md.ejs

@@ -0,0 +1,27 @@
+## 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)

+
 ## 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).
-2. 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 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. It is recommended that you specify a `maxLedgerVersion` in the instructions when preparing a transaction because without it there is no way to know 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 `maxLedgerVersion` provided in the transaction instructions.
+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. 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 requires a *fee* to be paid in XRP. The fee is destroyed; it is not sent to any other party. The purpose of the fee is to prevent denial of service attacks on the Ripple network.
+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. The fee is like a bid in an auction for slots in the next ledger closing. If the fee you choose is too low, your transaction will not be included in the next ledger closing. You can get an estimate of the fee required to be included in the next ledger closing with the [getFee](#getfee) method.

+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.

-A hash of the transaction that can be used to identify it. A transaction can be looked up by its ID using the [getTransaction](#gettransaction) method.

+You can look up a transaction by ID using the [getTransaction](#gettransaction) method.
