 ### Requirements
 
-+ **[Node v10](https://nodejs.org/)** is recommended. Other versions may work but are not frequently tested.
++ **[Node.js v14](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
+## Getting Started
+
+See also: [RippleAPI Beginners Guide](https://xrpl.org/get-started-with-rippleapi-for-javascript.html)
 
 In an existing project (with `package.json`), install `ripple-lib`:
 ```
 $ yarn add ripple-lib
 ```
 
+Then see the [documentation](#documentation).
+
+### Using ripple-lib with React Native
+
+If you want to use `ripple-lib` with React Native you will need to have some of the NodeJS modules available. To help with this you can use a module like [rn-nodeify](https://github.com/tradle/rn-nodeify).
+
+1. Install dependencies (you can use `npm` as well):
+
+    ```shell
+    yarn add react-native-crypto
+    yarn add ripple-lib 
+    # install peer deps
+    yarn add react-native-randombytes
+    # install latest rn-nodeify
+    yarn add rn-nodeify@latest --dev
+    ```
+
+2. After that, run the following command:
+
+    ```shell
+    # install node core shims and recursively hack package.json files
+    # in ./node_modules to add/update the "browser"/"react-native" field with relevant mappings
+    ./node_modules/.bin/rn-nodeify --hack --install
+    ```
+
+3. Enable `crypto`:
+
+    `rn-nodeify` will create a `shim.js` file in the project root directory.
+    Open it and uncomment the line that requires the crypto module:
+
+    ```javascript
+    // If using the crypto shim, uncomment the following line to ensure
+    // crypto is loaded first, so it can populate global.crypto
+    require('crypto')
+    ```
+
+4. Import `shim` in your project (it must be the first line):
+
+  ```javascript
+  import './shim'
+  ...
+  ```
+
+### Using ripple-lib with Deno
+
+Until official support for [Deno](https://deno.land) is added, you can use the following work-around to use `ripple-lib` with Deno:
+
+```javascript
+import ripple from 'https://dev.jspm.io/npm:ripple-lib';
+
+(async () => {
+  const api = new (ripple as any).RippleAPI({ server: 'wss://s.altnet.rippletest.net:51233' });
+  const address = 'rH8NxV12EuV...khfJ5uw9kT';
+
+  api.connect().then(() => {
+    api.getBalances(address).then((balances: any) => {
+      console.log(JSON.stringify(balances, null, 2));
+    });
+  });
+})();
+```

+ripple-lib uses the XRP Ledger's [WebSocket API](https://xrpl.org/rippled-api.html) for online functionality. You can use ripple-lib to call these APIs directly. 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).

+/**
+ * When implementing Reliable Transaction Submission, there are many potential solutions, each with different trade-offs. The main decision points are:
+ * 1) Transaction preparation:
+ *    - How do we decide which account sequence and LastLedgerSequence numbers to use?
+ *      (To prevent unintentional duplicate transactions, an {account, account_sequence} pair can be used as a transaction's idempotency key)
+ *    - How do we decide how much to pay for the transaction fee? (If our transactions have been failing due to low fee, we should consider increasing this value)
+ * 2) Transaction status retrieval. Options include:
+ *    - Poll for transaction status:
+ *      - On a regular interval (e.g. every 3-5 seconds), or
+ *      - When a new validated ledger is detected
+ *      + (To accommodate an edge case in transaction retrieval, check the sending account's Sequence number to confirm that it has the expected value;
+ *         alternatively, wait until a few additional ledgers have been validated before deciding that a transaction has definitively not been included in a validated ledger)
+ *    - Listen for transaction status: scan all validated transactions to see if our transactions are among them
+ * 3) What do we do when a transaction fails? It is possible to implement retry logic, but caution is advised. Note that there are a few ways for a transaction to fail:
+ *    A) `tec`: The transaction was included in a ledger but only claimed the transaction fee
+ *    B) `tesSUCCESS` but unexpected result: The transaction was successful but did not have the expected result. This generally does not occur for XRP-to-XRP payments
+ *    C) The transaction was not, and never will be, included in a validated ledger [3C]
+ *

+ * - https://xrpl.org/monitor-incoming-payments-with-websocket.html
+ *
+ * For the implementation in this example, we have made the following decisions:
+ * 1) The script will choose the account sequence and LastLedgerSequence numbers automatically. We allow ripple-lib to choose the fee.
+ *    Payments are defined upfront, and idempotency is not needed. If the script is run a second time, duplicate payments will result.
+ * 2) We will listen for notification that a new validated ledger has been found, and poll for transaction status at that time.
+ *    Futhermore, as a precaution, we will wait until the server is 3 ledgers past the transaction's LastLedgerSequence
+ *    (with the transaction nowhere to be seen) before deciding that it has definitively failed per [3C]
+ * 3) Transactions will not be automatically retried. Transactions are limited to XRP-to-XRP payments and cannot "succeed" in an unexpected way.
