+# 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 flow with the simplest transfer of value, for static data.
+
+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 publishes a dataset (= publishes a datatoken contract)
+
+For now, you're Alice:) Let's proceed.
+
+
+```javascript
+const { Ocean, Logger } = require('@oceanprotocol/lib')
+//you can use default ABIs or use custom ones
+//you can use default factoryAddress or use default one, depending on the network (auto-determined)
+const ocean = Ocean(rpc_url='https://pacific.oceanprotocol.com',factoryABI=Ocean.factoryABI,dataTokenABI=Ocean.dataTokenABI,factoryAddress='0x123',web3Provider: web3)
+
+const accounts = await ocean.accounts.list()
+erc20_address = ocean.datatokens.deployNewDT(publisher_service_url='123.com',account[0])
+```
+
+## 2. Alice mints 100 tokens
+
+```javascript
+const dataToken=Ocean.datatokens.loadContract(erc20_address)
+dataToken.mint(100,account[0])
+```
+
+## 3. Alice transfers 1 token to Bob
+
+```javascript
+//transfer amount to destination using account
+dataToken.transfer(1,bob_address, account[0])
+```
+
+## 4. Bob consumes dataset
+
+Now, we are Bob :)
+
+```javascript
+const ocean = Ocean(rpc_url='https://pacific.oceanprotocol.com',factoryABI=Ocean.factoryABI,dataTokenABI=Ocean.dataTokenABI,factoryAddress='0x123',web3Provider: web3)
+
+const accounts = await ocean.accounts.list()
+const account=account[0]
+
+const asset=ocean.assets.loadFromDataToken(erc20_address)
+
+const file=asset.download()
+
+```
+where
+```javascript
+class assets{
+    async function download(asset){
+        const publisher = Ocean.publisher.loadFromERC20(ERC20address)
+        const transaction = publisher.prepare(asset.ERC20address)
+        await account.signTransaction(transaction)
+        const file=await publisher.download(asset.ERC20address)
+        return file
+    }
+}
+```
