+
+# Get the binary
+Running following command to build Wayang and generate the tar.gz  
+```shell
+cd incubator-wayang
+./mvnw clean package -pl :wayang-assembly -Pdistribution 
+```
+Then you can find the `wayang-assembly-0.6.1-SNAPSHOT-dist.tar.gz` under `wayang-assembly/target` directory.
+
+
+# Prepare the environment
+## Wayang
+```shell
+tar -xvf wayang-assembly-0.6.1-SNAPSHOT-dist.tar.gz
+cd wayang-0.6.1-SNAPSHOT
+```
+
+In linux
+```shell 
+echo "export WAYANG_HOME=$(pwd)" >> ~/.bashrc
+echo "export PATH=${PATH}:${WAYANG_HOME}/bin" >> ~/.bashrc
+source ~/.bashrc
+```
+In MacOS
+```shell 
+echo "export WAYANG_HOME=$(pwd)" >> ~/.zshrc
+echo "export PATH=${PATH}:${WAYANG_HOME}/bin" >> ~/.zshrc
+source ~/.zshrc
