+# Supply chain & data auditing
+
+This repository containts an Ethereum DApp that demonstrates a Supply Chain flow between a Seller and Buyer. The user story is similar to any commonly used supply chain process. A Seller can add items to the inventory system stored in the blockchain. A Buyer can purchase such items from the inventory system. Additionally a Seller can mark an item as Shipped, and similarly a Buyer can mark an item as Received.
+
+The DApp User Interface when running should look like...

+
+## Getting Started
+
+These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
+
+### Prerequisites
+
+Please make sure you've already installed ganache-cli, Truffle and enabled MetaMask extension in your browser.
+
+```
+Give examples (to be clarified)
+```
+
+### Installing
+
+A step by step series of examples that tell you have to get a development env running
+
+Clone this repository:
+
+```
+git clone https://github.com/udacity/nd1309/tree/master/course-5/project-6
+```
+
+Change directory to ```project-6``` folder and install all requisite npm packages (as listed in ```package.json```):
+
+```
+cd project-6
+npm install
+```
+
+Launch Ganache:
+
+```
+ganache-cli -m "spirit supply whale amount human item harsh scare congress discover talent hamster"
+```
+
+Your terminal should look something like this:
+
+![truffle test](images/ganache-cli.png)
+
+In a separate terminal window, Compile smart contracts:
+
+```
+truffle compile
+```
+
+Your terminal should look something like this:
+
+![truffle test](images/truffle_compile.png)
+
+This will create the smart contract artifacts in folder ```build\contracts```.
+
+Migrate smart contracts to the locally running blockchain, ganache-cli:
+
+```
+truffle migrate
+```
+
+Your terminal should look something like this:
+
+![truffle test](images/truffle_migrate.png)
+
+Test smart contracts:
+
+```
+truffle test
+```
+
+All 10 tests should pass.
+
+![truffle test](images/truffle_test.png)
+
+In a separate terminal window, launch the DApp:
+
+```
+npm run dev
+```
+
