-## @0xproject/kovan_faucets
-
-This faucet dispenses 0.1 test ether to one recipient per second and 0.1 test ZRX every 5 seconds. It has a max queue size of 1000.
-
-## Installation
-
-This is a private package and therefore is not published to npm. In order to build and run this package locally, see the [Install Dependencies](#Install-Dependencies) section and onwards below.
-
-## Contributing
-
-We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
-
-Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
-
-### Install Dependencies
-
-If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
-
-```bash
-yarn config set workspaces-experimental true
-```
-
-Then install dependencies
-
-```bash
-yarn install
-```
-
-### Start
-
-Set the following environment variables:
-
-```bash
-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`.
-
-```bash
-yarn 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`.
-
-### Docker configs
-
-```
-docker run -d \
--p 80:3000 \

+## @0xproject/testnet_faucets
+
+This faucet dispenses 0.1 test ether to one recipient per second and 0.1 test ZRX every 5 seconds. It has a max queue size of 1000.
+
+## Installation
+
+This is a private package and therefore is not published to npm. In order to build and run this package locally, see the [Install Dependencies](#Install-Dependencies) section and onwards below.
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Dependencies
+
+If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
+
+```bash
+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Start
+
+Set the following environment variables:
+
+```bash
+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`.
+
+```bash
+yarn 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`.
+
+### Docker configs
+
+```
+docker run -d \
