    the code of the file until where you have to start completion: use rocket::Request;

use rocket_dyn_templates::{Temp
    
pub fn customize(tera: &mut Tera) {
    tera.add_raw_template("tera/about.html", r#"
        {% extends "tera/base" %}

        {% block content %}
            <section id="about">
              <h1>About - Here's another page!</h1>
