-##Getting Started
+## Getting Started
 
-Install `ripple-lib` using npm:
+See also: [RippleAPI Beginners Guide](https://ripple.com/build/rippleapi-beginners-guide/)
+
+### Requirements
+
++ **[Node v10](https://nodejs.org/)** is recommended. Other versions may work but are not frequently tested.
++ **[Yarn](https://yarnpkg.com/)** is recommended. `npm` may work but we use `yarn.lock`.
+
+### Install
+
+In an existing project (with `package.json`), install `ripple-lib`:
 ```
-  $ npm install ripple-lib
+$ yarn add ripple-lib
 ```
 
-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)
+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
+**What is ripple-lib used for?** Here's a [list of applications](APPLICATIONS.md) that use `ripple-lib`. Open a PR to add your app or project to the list!
+
+### Mailing Lists
+
+We have a low-traffic mailing list for announcements of new ripple-lib releases. (About 1 email per week)
+
++ [Subscribe to ripple-lib-announce](https://groups.google.com/forum/#!forum/ripple-lib-announce)
+
+If you're using the XRP Ledger in production, you should run a [rippled server](https://github.com/ripple/rippled) and subscribe to the ripple-server mailing list as well.
+
++ [Subscribe to ripple-server](https://groups.google.com/forum/#!forum/ripple-server)
+
+## Development
+
+To build the library for Node.js:
+```
+$ yarn compile
+```
+
+The TypeScript compiler will [output](./tsconfig.json#L7) the resulting JS files in `./dist/npm/`.
+
+To build the library for the browser:
+```
+$ yarn build
+```
+
+Gulp will [output](./Gulpfile.js) the resulting JS files in `./build/`.
+
+For details, see the `scripts` in `package.json`.
+
+## 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`
+3. `yarn test`
 
-##Generating Documentation
+Also, run `yarn lint` to lint the code with `tslint`.
 
-The continuous integration tests require that the documentation stays up-to-date. If you make changes the the JSON schemas, fixtures, or documentation sources, you must update the documentation by running `npm run docgen`.

+## Address
 
 ```json

-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`.
+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 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.

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).
+**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). This smallest unit is called a "drop". XRP has a maximum value of `100000000000` (1e11). Some RippleAPI methods accept XRP in order to maintain compatibility with older versions of the API. For consistency with the `rippled` APIs, we recommend formally specifying XRP values in *drops* in all API requests, and converting them to XRP for display. This is similar to Bitcoin's *satoshis* and Ethereum's *wei*. 1 XRP = 1,000,000 drops.
 
 **Non-XRP values** have 16 decimal digits of precision, with a maximum value of `9999999999999999e80`. The smallest positive non-XRP value is `1e-81`.

+## prepareTransaction
+
+`prepareTransaction(transaction: object, instructions: object): Promise<object>`
+
+Prepare a transaction. The prepared transaction must subsequently be [signed](#sign) and [submitted](#submit).
+
+This method works with any of [the transaction types supported by rippled](https://developers.ripple.com/transaction-types.html).
+
+Notably, this is the preferred method for preparing a `DepositPreauth` transaction (added in rippled 1.1.0).
+
+### Parameters
+
+Name | Type | Description
+---- | ---- | -----------
+transaction | [transaction](https://developers.ripple.com/transaction-formats.html) | The specification (JSON) of the transaction to prepare. Set `Account` to the address of the account that is creating the transaction. You may omit auto-fillable fields like `Fee`, `Flags`, and `Sequence` to have them set automatically.
+instructions | [instructions](#transaction-instructions) | *Optional* Instructions for executing the transaction.
+
+### Return Value
+
+This method returns a promise that resolves with an object with the following structure:
+
+<aside class="notice">
+All "prepare*" methods have the same return type.
+</aside>

+
+ripple-lib relies on [rippled APIs](https://ripple.com/build/rippled-apis/) for all online functionality. With ripple-lib version 1.0.0 and higher, you can easily access rippled APIs through ripple-lib. Use the `request()`, `hasNextPage()`, and `requestNextPage()` methods:
+* Use `request()` to issue any `rippled` command, including `account_currencies`, `subscribe`, and `unsubscribe`. [Full list of API Methods](https://ripple.com/build/rippled-apis/#api-methods). 
+* Use `hasNextPage()` to determine whether a response has more pages. This is true when the response includes a [`marker` field](https://ripple.com/build/rippled-apis/#markers-and-pagination).
+* Use `requestNextPage()` to request the next page of data.
+
+When using rippled APIs:
+* [Specify XRP amounts in drops](https://developers.ripple.com/basic-data-types.html#specifying-currency-amounts).
+* [Specify timestamps as the number of seconds since the "Ripple Epoch"](https://developers.ripple.com/basic-data-types.html#specifying-time).
+* Instead of `counterparty`, use `issuer`.
+
+## Listening to streams
+
+The `rippled` server can push updates to your client when various events happen. Refer to [Subscriptions in the `rippled` API docs](https://developers.ripple.com/subscription-methods.html) for details.
+
+Note that the `streams` parameter for generic streams takes an array. For example, to subscribe to the `validations` stream, use `{ streams: [ 'validations' ] }`.
+
+The string names of some generic streams to subscribe to are in the table below. (Refer to `rippled` for an up-to-date list of streams.)
+
+Type | Description
+---- | -----------
+`server` | Sends a message whenever the status of the `rippled` server (for example, network connectivity) changes.
+`ledger` | Sends a message whenever the consensus process declares a new validated ledger.
+`transactions` | Sends a message whenever a transaction is included in a closed ledger.
+`transactions_proposed` | Sends a message whenever a transaction is included in a closed ledger, as well as some transactions that have not yet been included in a validated ledger and may never be. Not all proposed transactions appear before validation. Even some transactions that don't succeed are included in validated ledgers because they take the anti-spam transaction fee.
+`validations` | Sends a message whenever the server receives a validation message, also called a validation vote, regardless of whether the server trusts the validator.
+`manifests` | Sends a message whenever the server receives a manifest.
+`peer_status` | (Admin-only) Information about connected peer `rippled` servers, especially with regards to the consensus process.
+
+When you subscribe to a stream, you must also listen to the relevant message type(s). Some of the available message types are in the table below. (Refer to `rippled` for an up-to-date list of message types.)
+
+Type | Description
+---- | -----------
+`ledgerClosed` | Sent by the `ledger` stream when the consensus process declares a new fully validated ledger. The message identifies the ledger and provides some information about its contents.
+`validationReceived` | Sent by the `validations` stream when the server receives a validation message, also called a validation vote, regardless of whether the server trusts the validator.
+`manifestReceived` | Sent by the `manifests` stream when the server receives a manifest.
+`transaction` | Sent by many subscriptions including `transactions`, `transactions_proposed`, `accounts`, `accounts_proposed`, and `book` (Order Book). See [Transaction Streams](https://ripple.com/build/rippled-apis/#transaction-streams) for details.
+`peerStatusChange` | (Admin-only) Reports a large amount of information on the activities of other `rippled` servers to which the server is connected.
+
+To register your listener function, use `connection.on(type, handler)`.
+
+Here is an example of listening for transactions on given account(s):
+```
+const account = 'rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn' // Replace with the account you want notifications for
+api.connect().then(() => { // Omit this if you are already connected
+
+  // 'transaction' can be replaced with the relevant `type` from the table above
+  api.connection.on('transaction', (event) => {
+
+      // Do something useful with `event`
+      console.log(JSON.stringify(event, null, 2))
+  })
+
+  api.request('subscribe', {
+      accounts: [ account ]
+  }).then(response => {
+      if (response.status === 'success') {
+          console.log('Successfully subscribed')
+      }
+  }).catch(error => {
+      // Handle `error`
+  })
+})
+```
+
+The subscription ends when you unsubscribe or the WebSocket connection is closed.
+
+For full details, see [rippled Subscriptions](https://ripple.com/build/rippled-apis/#subscriptions).

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.
 
+For a multi-signed transaction, ripple-lib automatically multiplies the `fee` by (1 + Number of Signatures Provided). For example, if you set `instructions.fee = '0.000020'` and `instructions.signersCount = 2`, the prepared transaction's `Fee` will be 20 drops × (1 + 2 Signatures) = 60 drops. See [Transaction Cost](https://developers.ripple.com/transaction-cost.html).
+
 ## 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.

docs/src/txFlags.md.ejs

+## txFlags
+
+`txFlags.TRANSACTION_TYPE.FLAG`
+
+This object provides constants for use when creating or interpreting transaction flags. Most transactions have a set of bit-flags that represent various options that affect how a transaction should behave. These options are represented as binary values that can be combined with bitwise-or operations to encode multiple flags at once.
+
+Most flags only have meaning for a specific transaction type. The same bitwise value may be reused for flags on different transaction types, so it is important to pay attention to the transaction type when setting and reading flags.
+
+Bits that are not defined as flags MUST be 0.
+
+### Global Flag
+
+Applies globally to all transactions.
+
+`txFlags.Universal.FullyCanonicalSig`: Require a fully-canonical signature. When preparing transactions, ripple-lib enables this flag for you.
+
+### Payment Flags
+
+`txFlags.Payment.NoRippleDirect`: Do not use the default path; only use specified paths. This is intended to force the transaction to take arbitrage opportunities. Most clients do not need this.
+
+`txFlags.Payment.PartialPayment`: If the specified destination amount cannot be sent without spending more than the source maxAmount, reduce the received amount instead of failing outright. See [Partial Payments](https://developers.ripple.com/partial-payments.html) for more details.
+
+`txFlags.Payment.LimitQuality`: Only take paths where all the conversions have an input:output ratio that is equal or better than the ratio of `destination.amount`:`source.maxAmount`. See [Limit Quality](https://developers.ripple.com/payment.html#limit-quality) for details.
+
+### OfferCreate Flags
+
+`txFlags.OfferCreate.Passive`: If enabled, the offer does not consume offers that exactly match it, and instead becomes an Offer object in the ledger. It still consumes offers that cross it.
+
+`txFlags.OfferCreate.ImmediateOrCancel`: Treat the offer as an Immediate or Cancel order. If enabled, the offer never becomes a ledger object: it only tries to match existing offers in the ledger.
+
+`txFlags.OfferCreate.FillOrKill`: Treat the offer as a Fill or Kill order.
+
+`txFlags.OfferCreate.Sell`: Treat the offer as a Sell order. With `order.direction = 'sell'`, exchange the entire `order.quantity`, even if it means obtaining more than the `order.totalPrice` amount in exchange. If using `prepareOrder`, ripple-lib sets this flag for you.
+
+### TrustSet Flags
+
+`txFlags.TrustSet.SetAuth`: Authorize the other party to hold issuances from this account. (No effect unless using the AccountSet.RequireAuth flag.) Cannot be unset.
+
+`txFlags.TrustSet.NoRipple`:  Obsolete.
+
+`txFlags.TrustSet.SetNoRipple`: Blocks [rippling](https://developers.ripple.com/rippling.html) between two trustlines of the same currency, if this flag is set on both.
+
+`txFlags.TrustSet.ClearNoRipple`: Clears the No-[Rippling](https://developers.ripple.com/rippling.html) flag.
+
+`txFlags.TrustSet.SetFreeze`: Freeze the trustline. A non-XRP currency can be frozen by the exchange or gateway that issued it. XRP cannot be frozen.
+
+`txFlags.TrustSet.ClearFreeze`: Unfreeze the trustline.
+
+### AccountSet Flags
+
+You can use the `prepareSettings` method to change your account flags. This method uses AccountSet flags internally.
+
+In the rippled API, Account Flags can be enabled and disabled with the SetFlag and ClearFlag parameters. See [AccountSet Flags](https://developers.ripple.com/accountset.html#accountset-flags).
+
+The AccountSet transaction type has some transaction flags, but their use is discouraged.
+
+* `txFlags.AccountSet.RequireDestTag`
+* `txFlags.AccountSet.OptionalDestTag`
+* `txFlags.AccountSet.RequireAuth`
+* `txFlags.AccountSet.OptionalAuth`
+* `txFlags.AccountSet.DisallowXRP`
+* `txFlags.AccountSet.AllowXRP`
+
+### PaymentChannelClaim Flags
+
+`txFlags.PaymentChannelClaim.Renew`: Clear the channel's Expiration time. (Expiration is different from the channel's immutable CancelAfter time.) Only the source address of the payment channel can use this flag.
+
+`txFlags.PaymentChannelClaim.Close`: Request to close the channel. Only the channel source and destination addresses can use this flag. This flag closes the channel immediately if it has no more XRP allocated to it after processing the current claim, or if the destination address uses it. If the source address uses this flag when the channel still holds XRP, this schedules the channel to close after SettleDelay seconds have passed. (Specifically, this sets the Expiration of the channel to the close time of the previous ledger plus the channel's SettleDelay time, unless the channel already has an earlier Expiration time.) If the destination address uses this flag when the channel still holds XRP, any XRP that remains after processing the claim is returned to the source address.
+
+### Other Transaction Types
+
+The remaining transaction types do not have any flags at this time.
+
+* OfferCancel
+* SetRegularKey
+* SignerListSet
+* EscrowCreate
+* EscrowFinish
+* EscrowCancel
+* PaymentChannelCreate
+* PaymentChannelFund

+## xrpToDrops
+
+`xrpToDrops(xrp: string | BigNumber): string`
+
+Converts an XRP amount to drops. 1 XRP = 1,000,000 drops, so 1 drop = 0.000001 XRP. This method is useful when converting amounts for use with the rippled API, which requires XRP amounts to be specified in drops.

+### Parameters
+
+`xrp`: A string or BigNumber representing an amount of XRP. If `xrp` is a string, it may start with `-`, must contain at least one number, and may contain up to one `.`. This method throws a `ValidationError` for invalid input.
+
+### Return Value
+
+A string representing an equivalent amount of drops.
