## Quick start
- Basic requirement
- JDK 1.8+
- IntelliJ idea
- maven
- Clone project
````
git clone https://github.com/CoderiGenius/RocksRaft.git
````
- Import in to idea as maven project
- Config and start the example of 3 nodes scenario.
- Config the three yml files in **src/main/resources**
- Start the main function with files listed below
- src/main/java/Start.java
- src/main/java/Start2.java
- src/main/java/Start3.java
- Wait until the nodes come up.
- Run the src/main/java/ClientExample.java
- You should be able to see the log of appendEnties and the procedures of applying to statemachine.
- Log example:
```
