move to new xrpl library

@@ -12,61 +12,40 @@ xrpio is a library that allows you to write and read arbitrary data in the rippl
 npm i xrpio
 ```
 
+# How it works
+
+Transactions on the ripple blockchain are allowed to carry up to 1kB of arbitrary data via the memo field. 
+We can use this to store data of any size by building a tree of references between these transactions that can then be reassembled by reading them back from the blockchain.
+In order to generate these transactions xrpio sends payments with the minimum denomination between two wallets controlled by the user. 
+
+xrpio automatically takes care of the logistics behind this technique as well as compression of the data.
+
+Highly simplified, you can visualize the process like this:
+
+![xrpio treewrite](https://i.imgur.com/G2HofSE.gif)
+
+In practice each node does of course store significantly more data.

 # Caution
 This library is in an early stage of development and **breaking changes may occur spontaneously and without regard of semantic versioning until the v1.0.0 release**.

 # Quickstart
 ```typescript
-import {RippleAPI} from 'ripple-lib'
-import {treeRead, treeWrite} from 'xrpio'
+import { xrpIO } from "xrpio"
 
-const api = new RippleAPI({ server: "..." }) 
+const api = new xrpIO("wss://some_ripple_node.net:51233")
 await api.connect()
 
-const dataRootHash = await treeWrite(
-    api, 
-    "Arbitrary string data 123", 
-    { 
-        address: "Sender address", 
-        secret: "Sender private key"
-    }, 
-    "Receiver address"
-)
-
-const data = await treeRead(api, [dataRootHash])
-console.log(data) //"Arbitrary string data 123"
-```
+txHash = await api.treeWrite("arbitrary text 123", receiveWallet.address, sendWallet.secret)
+data = await api.treeRead([txHash])
+
+console.log(data) //"arbitrary text 123"
+
 
-# A simple ready-to-run example for the testnet
-```typescript
-import { treeRead, treeWrite, Wallet } from 'xrpio'
-import { RippleAPI } from 'ripple-lib'
-import fetch from 'node-fetch'
-
-export const makeTestnetWallet = () : Promise<Wallet> => fetch('https://faucet.altnet.rippletest.net/accounts', {
-    method: 'POST',
-    headers: {
-        'Accept': 'application/json',
-        'Content-Type': 'application/json'
-    },
-}).then((raw:any) => {
-    return raw.json().then(content => content.account)
-});
-
-(async()=>{
-    const api = new RippleAPI({server: 'wss://s.altnet.rippletest.net:51233'})
-    await api.connect()
-    const fromWallet = await makeTestnetWallet()
-    const toWallet = await makeTestnetWallet()
-    await new Promise((res, rej) => setTimeout(res, 10000)) //it takes a moment for the wallets to become active
-
-    const rootHash = await treeWrite(api, "test123", fromWallet, toWallet.address)
-    const data = await treeRead(api, [rootHash])
-    console.log(data)
