Eth Private Network

Install the GUI app http://truffleframework.com/ganache/. When the app is started...

• Settings > Server > Port Number. Set this to 8545 or whatever you have set in the config.json. You'll only need to do this once.
• Make sure you are automining
• Within the app it's going to give you a number of accounts with tons of ETH. Import one of these into metamask via the private key.
• If you ever restart Ganache. Under settings in metamask. Click Reset Account. Nothing will work without this.

Building Contract

• ./bin/build.js. Contract address will be outputed. View ganache block explorer to ensure it happened.

Running Web Server

• ./bin/startup.sh or node ./src/App.js.
• http://localhost:9090 will be default on config.json
• As it will stated in design. If you change the server /templates/ rerun the server.

MetaMask

• change your node to http://localhost:8545.
• There is bug within metamask. If you change your node, you will need restart the browser or you will not receive websocket events from 8545.

Design

• /templates/ these are pre built from ./src/App.js. main.html is the index. It's needed to load the current contract address. See scripts in main.html for the reasoning. If you have changed one of these templates, rerun the server to see changes.
• /web/templates/ frontend templates
• To get a notes in design run node ./utils/create-note.js or node ./utils/create-mass-notes.js
