To run an example, use the command `cargo run --example <Example>`, and add the option `--features x11` or `--features wayland` to force the example to run on a specific window compositor, e.g.
Due to changes and additions to APIs, there are often differences between the development examples and the released versions of Bevy on crates.io.
If you are using a release version from [crates.io](https://crates.io/crates/bevy), view the examples by checking out the appropriate git tag, e.g., users of `0.3` should use the examples on [https://github.com/bevyengine/bevy/tree/v0.3.0/examples](https://github.com/bevyengine/bevy/tree/v0.3.0/examples)
If you have cloned bevy's repo locally, `git checkout` with the appropriate version tag.

Bevy by default targets Android API level 29 in its examples which is the [Play Store's minimum API to upload or update apps](https://developer.android.com/distribute/best-practices/develop/target-sdk). Users of older phones may want to use an older API when testing.
To use a different API, the following fields must be updated in Cargo.toml:
`hello_wasm` | [`wasm/hello_wasm.rs`](./wasm/hello_wasm.rs) | Runs a minimal example that logs "hello world" to the browser's console
`headless_wasm` | [`wasm/headless_wasm.rs`](./wasm/headless_wasm.rs) | Sets up a schedule runner and continually logs a counter to the browser's console
`assets_wasm` | [`wasm/assets_wasm.rs`](./wasm/assets_wasm.rs) | Demonstrates how to load assets from wasm
`winit_wasm` | [`wasm/winit_wasm.rs`](./wasm/winit_wasm.rs) | Logs user input to the browser's console. Requires the `bevy_winit` features
