[Docs] Create your first plugin example in documentation is not working

[SirMishaa]

Hello, the part Create your first plugin in the documentation is not working. It looks like there is a PluginGroup trait that need to be implemented.

Can you update the documentation in accordance to avoid troubling new user?

use bevy::prelude::{App, Commands, Component, Plugin, Query, With};
use bevy::MinimalPlugins;

#[derive(Component)]
struct Person;

#[derive(Component)]
struct Name(String);

struct HelloPlugin;

impl Plugin for HelloPlugin {
    fn build(&self, app: &mut App) {
        app.add_startup_system(add_people).add_system(greet_people);
    }
}

fn main() {
    App::new()
        .add_plugins(MinimalPlugins)
        .add_plugins(HelloPlugin)
        .run()
}

fn greet_people(query: Query<&Name, With<Person>>) {
    for name in query.iter() {
        println!("hello {}!", name.0);
    }
}

fn add_people(mut commands: Commands) {
    commands.spawn((Person, Name("Elaina Proctor".to_string())));
    commands.spawn((Person, Name("Renzo Hume".to_string())));
    commands.spawn((Person, Name("Zayna Nieves".to_string())));
}

.add_plugins(HelloPlugin)

Tiny but critical typo there :)

.add_plugins(HelloPlugin)

Oh, I'm so sorry, my bad ! :(

I'm closing, this is working.

No worries, this is a bit of a footgun.
