+# ERC-20 RESTful service
+
+This application provides a RESTful service for creating and managing 
+[ERC-20 tokens](https://github.com/ethereum/EIPs/issues/20). 
+It has been built using [Spring Boot](https://projects.spring.io/spring-boot/), and 
+[web3j](https://web3j.io).
+
+It works with both [Geth](https://github.com/ethereum/go-ethereum), 
+[Parity](https://github.com/paritytech/parity), and 
+[Quorum](https://github.com/jpmorganchase/quorum).
+
+For Quorum, the RESTful semantics are identical, with the exception that if you wish to create 
+a private transaction, you populate a HTTP header name *privateFor* with a comma-separated
+list of public keys
+
+
+## Build
+
+To build a runnable jar file:
+
+```bash
+./gradlew clean build
+```
+
+## Run
+
+Using Java 1.8+:
+
+```bash
+java -jar build/libs/azure-demo-0.1.jar 
+```
+
+By default the application will log to a file named erc20-web3j.log. 
+
+
+## Configuration
+
+The following default properties are used in the application:
+
+```properties
+# Port for service to bind to
+port=8080
+# Log file path and name
+logging.file=logs/erc20-rest-service.log
+
+# Endpoint of an Ethereum or Quorum node we wish to use. 
+# To use IPC simply provide a file path to the socket, such as /path/to/geth.ipc
+nodeEndpoint=http://localhost:22000
+# The Ethereum or Quorum address we wish to use when transacting.
+# Note - this address must be already unlocked in the client
+fromAddress=0xed9d02e382b34818e88b88a309c7fe71e65f419d
+```
+
+You can override any of these properties by creating a file name 
+*application.properties* in the root directory of your application, or in 
+*config/application.properties* relative to your root. If you'd rather use yaml, 
+simply change the filename to *application.yml*.
+
+
+## Usage
+
+All available application endpoints are documented using [Swagger](http://swagger.io/).
+
+You can view the Swagger UI at http://localhost:8080/swagger-ui.html. From here you
+can perform all POST and GET requests easily to facilitate deployment of, transacting 
+with, and querying state of ERC-20 tokens.
+
+![alt text](https://github.com/blk-io/erc20-rest-service/raw/master/images/full-swagger-ui.png "Swagger UI screen capture")
+
+
+## Docker
+
+We can use [Docker](https://www.docker.com/) to easily spin up a arbritrary instance 
+of our service connecting to an already running Ethereum or Quorum network.
+
+All you need to do is build the Dockerfile:
+
+```docker
+docker build -f docker/Dockerfile -t blk-io/erc20-service .
+```
+
+Then either run it with default configuration:
+```docker
+docker run -p 8080:8080 -v "$PWD/logs":/logs blk-io/erc20-service
+```
+
+Or with a custom configuration:
+
+```docker
+export PORT=8081
+docker run -p ${PORT}:${PORT} -v "$PWD/logs":/logs \
+    -e ENDPOINT="http://localhost:22001" \
+    -e FROMADDR="0xca843569e3427144cead5e4d5999a3d0ccf92b8e" \
+    -e PORT="$PORT" \
+    blk-io/erc20-service
+```
