   alias ignite3="${ignite-3-cli folder}/bin/ignite3" >> ~/.bash_profile
   source bin/ignite_completion.sh 

4. (optional) If the cluster is not initialized then initialize the cluster:

   ignite3 cluster init --name=ignite-cluster --url=http://localhost:10300
   

5. Run the preferred example in the IDE.
