 # Building the source
 Building java-tron requires `git` and `Oracle JDK 1.8` to be installed, other JDK versions are not supported yet. Make sure you operate on `Linux` and `MacOS` operating systems.
 
-## Getting the Source Code
+Clone the repo and switch to the `master` branch
 
   ```bash
   $ git clone https://github.com/tronprotocol/java-tron.git
+  $ cd java-tron
   $ git checkout -t origin/master
   ```

-## Build
-
+then run the following command to build java-tron, the `FullNode.jar` file can be found in `java-tron/build/libs/` after build successful.
 ```bash
-$ cd java-tron
 $ ./gradlew clean build -x test
 ```

 ## Running a full node for mainnet
-  Full node has full historical data, it is the entry point into the TRON network , it can be used by other processes as a gateway into the TRON network via HTTP and GRPC endpoints. You can interact with the TRON network through full node：transfer assets, deploy contracts, interact with contracts and so on. `-c ` parameter specifies a configuration file to run a full node:

-## Running a super representative node for mainnet  
-  Adding the `--witness` parameter to the startup command, full node will run as a super representative node. The super representative node supports all the functions of the full node and also supports block production. Before running, make sure you have a super representative account and get votes from others，once the number of obtained votes ranks in the top 27, your super representative node will participate in block production.
