1 - Instalar Ganache.
2 - Criar funções do abi no Remix

    pragma solidity ^0.5.0;

contract TodoList{
    uint public taskCount;
    
    struct Task{
        string taskName;
        bool isComplet;
    }
    mapping(uint => Task) public todos;
    
    event TaskCreated(string task, uint taskNumber);
    
    constructor() public {
        taskCount = 0;
    }
    
    function createTask(string memory _taskName) public {
        //add task mapping and imcrement taskCount
        todos[taskCount++] = Task(_taskName, false);
        //emit event
        emit TaskCreated(_taskName, taskCount - 1);
    }
    
}

3 - npm install -g truffle e dentro da pasta do projeto $truffle init
3.1 - Na pasta contracts criada após o comando anterios colar criar um arquivo TodoList.sol e colar sua classe do Remix la assim como no passo 2
4 - Buildar seu código no remix
5 - Deploy do seu contrato pelo remix
6 - em seu truffle-config.js

module.exports = {
  networks:{
    development:{
      host:"<seu-ip-no-ganache>",
      port: port-ganache,
      network_id:"*"
    },
    advanced:{
      websockets : true,
    },
    
  },
  contracts_build_directory:"./assets/files/",//diretorio onde ficarao os arquivos abi *.json
  compilers: {
    solc: {
      optimizer :{
        enabled: true,
        runs: 200
      }
    }
  }
}

7 - Criar arquivo na pasta migrations gerada pelo truffle init com o seguinte conteudo

const TodoList = artifacts.require("TodoList");

module.exports = function (deployer) {
  deployer.deploy(TodoList);
};

8 - Rode $ truffle migrate
