 # spark-tensorflow-connector
 
 This repo contains a library for loading and storing TensorFlow records with [Apache Spark](http://spark.apache.org/).
@@ -19,19 +21,34 @@ None.
 2. [Apache Maven](https://maven.apache.org/)
 
 ## Building the library
-Build the library using Maven as shown below.
+You can build library using both Maven and SBT build tools
+
+#### Maven
+Build the library using Maven(3.3) as shown below
 
 ```sh
 mvn clean install
 ```
 
+#### SBT 
+Build the library using SBT(0.13.13) as show below
+```sh
+sbt clean assembly
+```
+
 ## Using Spark Shell
 Run this library in Spark using the `--jars` command line option in `spark-shell` or `spark-submit`. For example:
 
+Maven Jars
 ```sh
 $SPARK_HOME/bin/spark-shell --jars target/spark-tensorflow-connector-1.0-SNAPSHOT.jar,target/lib/tensorflow-hadoop-1.0-01232017-SNAPSHOT-shaded-protobuf.jar
 ```
 
+SBT Jars
+```sh
+$SPARK_HOME/bin/spark-shell --jars target/scala-2.11/spark-tensorflow-connector-assembly-1.0-SNAPSHOT.jar
+```
+
 The following code snippet demonstrates usage.
