+ # ocean-lib
+
+
+`ocean-lib-js` is a Javascript/Typescript library to privately & securely publish, exchange, and consume data. With it, you can:
+* **Publish** data services: static data, streaming data, or compute-to-data. Every data service gets its own [ERC20](https://github.com/ethereum/EIPs/blob/7f4f0377730f5fc266824084188cc17cf246932e/EIPS/eip-20.md) token.
+* **Mint** data tokens for a given data service
+* **Transfer** data tokens to another owner
+* **Consume** data tokens, to access the service
+
+`ocean-lib-js` is part of the [Ocean Protocol](www.oceanprotocol.com) toolset.
+
+# Installation
+```
+// ES6
+import { Ocean, Logger } from '@oceanprotocol/lib'
+
+// ES2015
+const { Ocean, Logger } = require('@oceanprotocol/lib')
+
+```
+
+# Quickstart
+
+This section describes a marketplace flow with multiple services
+
+Here's the steps.
+1. Alice publishes a dataset (= publishes a datatoken contract)
+1. Alice mints 100 tokens
+1. Alice transfers 1 token to Bob
+1. Bob consumes dataset
+
+Let's go through each of these in detail.
+
+
+## 1. Alice hosts the dataset
+
+A locally providerService ,metadatastore and marketplace are required:
+
+Run the providerService and metadatastore:
+```
+docker run @oceanprotocol/provider-py:latest
+docker run @oceanprotocol/aquarius:latest
+docker run @oceanprotocol/marketplace:latest
+```
+
+
+## 2. Alice publishes a dataset (= publishes a datatoken contract)
+
+For now, you're Alice:) Let's proceed.
+
+
+```javascript
+const { Ocean, Logger } = require('@oceanprotocol/lib')
+
+const marketPlaceAddress='0x9876'
+//Alice's config
+const config={
+   network: 'rinkeby',
+   privateKey:'8da4ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f',
+   metadataStoreURI: 'localhost:5000',
+   providerUri: 'localhost:8030'
+}
+const ocean = Ocean(alice_config)
+const account = await ocean.accounts.list()[0]
+
+
+const myToken = ocean.datatoken.create(config.metadataStoreURI,account)
+//Alice allows MarketPlace to transfer 20 DT
+myToken.approve(marketPlaceAddress,20)
+
+const dt_address=myToken.getAddress()
+
+//create asset 1
+const metaData={
+   "did":"did:op:1234",
+   "owner":"0xaaaaa",
+   "dtAddress":dt_address,
+   "name":"Asset1",
+   "services="[
+      {  "id":0, "serviceEndpoint":"providerUri", "type":"download", "dtCost":10, "timeout":0,
+         "files":[{"url":"http://example.net"},{"url":"http://example.com" }]
+      },
+      { "id":1, "type":"compute", "serviceEndpoint":"providerUri", "dtCost":1,"timeout":3600},
+      { "id":2,   "type":"compute",  "serviceEndpoint":"providerUri",  "dtCost":2, "timeout":7200 },
+   ]
+}
+//create will encrypt the URLs using publisher and update the ddo before pushing to aquarius
+//create will require that metaData.dtAddress is a valid DT Contract address
+const asset = ocean.assets.create(metaData,account)
+const did = asset.did
+```
+
+
+
+## 3. Alice mints 100 tokens
+
+```javascript
+myToken.mint(100)
+```
+
+## 4. Exchange of value : How Bob gets DT
+```javascript
+const bob_config={
+   network: 'rinkeby',
+   privateKey:'1234ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f'  
+   marketPlaceUri: 'localhost:3000'
+}
+const bob_ocean = Ocean(bob_config)
+const bob_account = await bob_ocean.accounts.list()[0]
+
+const asset = ocean.assets.resolve(did)
+const serviceIndex = assets.findServiceByType('compute')
+const num_dt_needed = assets.getDtCost(serviceIndex)
+//Bob need to buy num_dt_needed . DTAddress = asset.dtAddress
+
+const {price, currency } = ocean.marketplace.getPrice(num_dt_needed,asset.dtAddress)
+bob_account.approve(price, currency, marketPlaceAddress)
+ocean.marketplace.buy(num_dt_needed,asset.dtAddress)
+```
+
+## 5. Bob consumes dataset
+
+Now, you are Bob :)
+
+
+```javascript
+
+const bob_config={
+   network: 'rinkeby',
+   privateKey:'1234ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f'  
+}
+const bob_ocean = Ocean(bob_config)
+
+
+const account = await bob_ocean.accounts.list()[0]
+const asset = ocean.assets.getFromDID(did)
+const serviceIndex = assets.findServiceByType('compute')
+
+export const rawAlgoMeta = {
+  rawcode: `console.log('Hello world'!)`,
+  format: 'docker-image',
+  version: '0.1',
+  container: {
+    entrypoint: 'node $ALGO',

+# Quickstart

+This section describes a flow with the simplest transfer of value, for static data.
+

+console.log(dt_address)
+```
+
+## 2. Alice hosts the dataset
+
+A locally providerService is required, which will serve just one file for this demo.
+Let's create the file to be shared:
+```
+touch /var/mydata/myFolder1/file
+````
+
+Run the providerService:
+(given that ERC20 contract address from the above is 0x1234)
+
+```
+ENV DT="{'0x1234':'/var/mydata/myFolder1'}"
+docker run @oceanprotocol/provider-py -e CONFIG=DT
