+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Start
+
+Set the following environment variables:
+
+```bash
+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}
+```
+
+If you want to talk to testrpc, set the following environment variable:
+
+```bash
+export FAUCET_ENVIRONMENT=development
+```
+
+Infura API Key can be requested here: https://infura.io/signup
+
+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`.
+
+```bash
+yarn dev
+```
+
+### Endpoints
+
+`GET /ping`
+
+Returns `pong`
+
+`GET /info`
+
+Returns a JSON payload describing the state of the queues for each network. For example:
+
+```json
+{
+    "3": {
+        "ether": {
+            "full": false,
+            "size": 4
+        },
+        "zrx": {
+            "full": false,
+            "size": 6
+        }
+    },
+    "42": {
+        "ether": {
+            "full": false,
+            "size": 8
+        },
+        "zrx": {
+            "full": false,
+            "size": 20
+        }
+    }
+}
+```
+
+`GET /ether/:recipient`
+
+Where recipient is a hex encoded Ethereum address prefixed with `0x`.
+
+`GET /zrx/:recipient`
+
+Where recipient is a hex encoded Ethereum address prefixed with `0x`.
+
+#### Parameters
+
+The endpoints `/ether` and `/zrx` take a query parameter named `networkId` to specify the desired network where you would like to receive the ETH or ZRX. For example:
+
+```bash
+curl -i http://localhost:3000/ether/0x14e2F1F157E7DD4057D02817436D628A37120FD1\?networkId=3
+```
+
+This command will request the local server to initiate a transfer of 0.1 ETH from the dispensing address to `0x14e2F1F157E7DD4057D02817436D628A37120FD1` on the Ropsten testnet.
+
+If no `networkId` is provided via query parameters the faucet will default to network 42 (Kovan)
+
