+A template project for getting started working on the Ethereum blockchain.
+This project comes with basic packages for compiling and deploying Solidity contracts with Truffle.
+
+Run `cp example.secrets.json secrets.json` and fill out the copied `secrets.json` with your information.
+
+From this directory, run `npm install` to install required packages.
+
+From there, we can create any contracts and deploy to development or public networks...
+### Development Deploy
+
+```asm
+npx truffle develop
+truffle(develop)> migrate

+### Public Network Deploy
+
+To deploy, you need ETH on a wallet connected to ropsten. Metamask is the wallet I use.
+I explain how to configure metamask on ropsten on [Knoats - Solidity](https://knoats.com/books/c/page/solidity)
+
+Give yourself test Ethereum with the [Ropsten ETH Faucet](https://faucet.ropsten.be)
+
+To deploy to ropsten test network, and verify using `truffle-verify-plugin` - 
+
+```asm
+npx truffle migrate --network ropsten
+npx truffle run verify Migrations --network ropsten
+```
+
+For a guide on how I configured this project, see [Knoats - Solidity](https://knoats.com/books/c/page/solidity)
