+### Using MXNet from source
+
+If you chose to "Build from Source" when following the [install instructions](https://mxnet.incubator.apache.org/install/index.html) (or the detailed [build from source instructions](https://mxnet.incubator.apache.org/install/build_from_source.html#installing-mxnet-language-bindings)), you can use your custom build instead of the build from maven. Use your build by editing the `pom.xml` file and replacing the `org.apache.mxnet` dependency with the following:
+
+```
+ <groupId>org.apache.mxnet</groupId>
+ <artifactId>mxnet-core_${scala.version}-${platform}-sources</artifactId>
+ <scope>system</scope>
+ <systemPath>/PathToMXNetSource/incubator-mxnet/scala-package/assembly/osx-x86_64-cpu/target/mxnet-full_${scala.version}-osx-x86_64-cpu-1.3.1-SNAPSHOT-sources.jar</systemPath>

+ </dependency>
+```
+
+Note that you have to edit both of the `systemPath` properties to point to your generated jar files.
