-# Yield app v2
+# Basic Sample Hardhat Project
 
-## A. Setup Blockchain Environment
+This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts.
 
-### Option 1: Run development environment locally **(Recommended for now)**
+Try running some of the following tasks:
 
-In a new console:
-
-1. **clone** the environments-v2 repo: `git clone https://github.com/yieldprotocol/environments-v2.git`
-2. **checkout tagged release** `git checkout RC4`
-3. **install** the environment `yarn`
-4. **Start a local hardhat chain instance**: `npx hardhat node`
-5. optional: **Add your testing account** to the list of accounts to be auto-funded with test tokens:
-
-   (edit `externalTestAccounts` array line 32 in file `./environments/development.ts` )
-
-In a new console
-
-1. **Run the dev environment deploy/setup** `npx hardhat run ./environments/development.ts --network localhost`
-
-### Option 2: Use Rinkeby Testnet
-
-No setup required, simply point metamask to the correct network
-
-## B. Run User Interface (this Repo):
-
-Fire up the UI locally:
-
-1. **install and run** `yarn && yarn start`
-2. In the browser, connect metamask to the localhost network, and reset the metamask account (for just in case).
+```shell
+npx hardhat accounts
+npx hardhat compile
+npx hardhat clean
+npx hardhat test
+npx hardhat node
+node scripts/sample-script.js
+npx hardhat help
