+Test Ether Faucet
+----------------------
+
+This faucet dispenses 0.1 test ether to one recipient per second. It has a max queue size of 1000.
+
+
+## Install
+
+Install project dependencies:
+
+```
+npm install
+```
+
+## Start
+
+Set the following environment variables:
+
+```
+export FAUCET_ENVIRONMENT=development
+export DISPENSER_ADDRESS=0x5409ed021d9299bf6814279a6a1411a7e866a631
+export DISPENSER_PRIVATE_KEY=f2f48ee19680706196e2e339e5da3491186e0c4c5030670656b0e0164837257d
+export FAUCET_ROLLBAR_ACCESS_KEY={GET_THIS_FROM_ROLLBAR_ACCOUNT_SETTINGS}
+export INFURA_API_KEY={GET_THIS_FROM_INFURA}
+```
+
+Infura API Key can be requested here: https://infura.io/register.html
+
+Note: The above public/private keys exist when running `testrpc` with the following option `--mnemonic concert load couple harbor equip island argue ramp clarify fence smart topic`.
+
+```
+npm run dev
+```
+
+## Endpoints
+
+```GET /ether/:recipient```
+
+Where recipient_address is a hex encoded Ethereum address prefixed with `0x`.
+
+```GET /zrx/:recipient```
+
+Where recipient_address is a hex encoded Ethereum address prefixed with `0x`.
+
+
