    Important Note before you start

As the EOSIO V1.3 was released this week we strongly do not recommend to use it for the hackathon. Please use EOSIO V1.2.5 to build your applications. To setup your EOSIO Developer Portal for correct version for the event, please click the following link: https://developers.eos.io/eosio-nodeos/v1.2.0/docs/?hackathon
