Minimal working example

Add dependencies to your Cargo.toml file:

[dependencies]
bevy = "0.14"
bevy_ecs_tiled = "0.4"
bevy_ecs_tilemap = "0.14"

Then add the plugin to your app and spawn a map:

use bevy::prelude::*;
use bevy_ecs_tiled::prelude::*;
use bevy_ecs_tilemap::prelude::*;

fn main() {
    App::new()
        // Add Bevy default plugins
        .add_plugins(DefaultPlugins)
        // Add bevy_ecs_tilemap plugin
        .add_plugins(TilemapPlugin)
        // Add bevy_ecs_tiled plugin
        .add_plugins(TiledMapPlugin::default())
        // Add our startup function to the schedule and run the app
        .add_systems(Startup, startup)
        .run();
}

fn startup(mut commands: Commands, asset_server: Res<AssetServer>) {
    // Spawn a 2D camera
    commands.spawn(Camera2dBundle::default());

    // Load the map: ensure any tile / tileset paths are relative to assets/ folder
    let map_handle: Handle<TiledMap> = asset_server.load("map.tmx");

    // Spawn the map with default options
    commands.spawn(TiledMapHandle(map_handle));
}

Please note that you should have the map.tmx file in your local assets/ folder, as well as required dependencies (for instance, associated tilesets).

You can customize various settings about how to load the map by inserting the TiledMapSettings component on the map entity.

Also, you can browse the examples for more advanced use cases.
