How to add send via SMTP in phpMailer?

Good morning,

I have the following code to send an email via PHPMailer.

<?php

    $GetPost = filter_input_array(INPUT_POST,FILTER_DEFAULT);

    $Erro      = true;
    $Tipo      = $GetPost['tipo'];
    $Nome      = $GetPost['nome'];
    $Email     = $GetPost['email'];
    $Telefone  = $GetPost['telefone'];
    $Cargo     = $GetPost['cargo'];
    $Curriculo = $_FILES['curriculo'];
    $Mensagem  = $GetPost['mensagem'];

    include_once 'PHPMailer/class.smtp.php';
    include_once 'PHPMailer/class.phpmailer.php';

    $Mailer = new PHPMailer;
    $Mailer->CharSet = "utf8";
    $Mailer->SMTPDebug = 3;

    $Mailer->FromName = "Jogo Digital";
    $Mailer->From = "[email protected]";
    $Mailer->AddAddress("[email protected]");
    $Mailer->IsHTML(true);
    $Mailer->Subject = "Novo currículo \"Trabalhe Conosco\" - {$Nome}";
    $Mailer->AddAttachment($Curriculo['tmp_name'], $Curriculo['name']);
    $Mailer->Body = "
    Novo currículo enviado por {$Nome}<br />
    Tipo: {$Tipo}<br /><br>
    <b>Dados:</b><br /><br>
    Email: {$Email}<br>
    Telefone: {$Telefone}<br>
    Cargo: {$Cargo}<br>
    Mensagem: {$Mensagem}<br>
    Curriculo: {$Curriculo}
    ";

    if(!$Mailer->Send()){
        echo "<script>alert('Não foi possível enviar, tente novamente!');window.history.back();</script>";
    } else {
        echo "<script>alert('Curriculo enviado com sucesso!');window.history.back();</script>";
    }

What should I enter in this code so that the sending is done by smtp? Because the way it is now, all the emails are falling in SPAM.

Thank you!
