Add bevy and bevy_pixels to Cargo.toml. Be sure to disable bevy's render and bevy_wgpu features (with default-features = false) as they will conflict with rendering provided by bevy_pixels.

[dependencies]
bevy = { version = "0.8", default_features = false }
bevy_pixels = { git = "https://github.com/dtcristo/bevy_pixels" }

Add PixelsPlugin to your Bevy project.

use bevy::prelude::*;
use bevy_pixels::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugin(PixelsPlugin)
        .add_system(main_system)
        .run();
}

Use PixelsResource in your systems.

fn main_system(mut pixels_resource: ResMut<PixelsResource>) {
    // Get a mutable slice for the pixel buffer
    let frame: &mut [u8] = pixels_resource.pixels.get_frame_mut();

    // Fill frame with pixel data
    // ...
}

This example is based off minimal-winit example from the pixels project.
