You are free to use a `bevy_xxx` name for your plugin, but please be reasonable. If you are about to claim a generic name like `bevy_animation`, `bevy_color`, or `bevy_editor`, please ask first. The rationale is explained [here](https://github.com/bevyengine/bevy/discussions/1202#discussioncomment-258907).
Indicating which version of your plugin works with which version of Bevy can be helpful for your users. Some of your users may be using an older version of Bevy for any number of reasons. You can help them find which version of your plugin they should use. This can be shown as a simple table in your readme with each version of Bevy and the corresponding compatible version of your plugin.
|bevy|bevy_awesome_plugin|
|---|---|
|0.4|0.3|
|0.3|0.1|
## Bevy Features
You should disable Bevy features that you don't use. This is because with Cargo, features are additive. Features that are enabled for Bevy in your plugin can't be disabled by someone using your plugin. You can find the list of features [here](cargo_features.md).
```
bevy = { version = "0.4", default-features = false, features = ["..."] }
You can specify the dependency [both as a version and with git](https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#multiple-locations), the version will be used if using the dependency from [crates.io](https://crates.io), the git dependency will be used otherwise.

Rust projects are often dual licensed with [MIT and Apache 2.0](https://www.rust-lang.org/policies/licenses). Bevy is licensed with [MIT](https://github.com/bevyengine/bevy/blob/main/LICENSE). Those are great options to license your plugin.
Tests are always good! For CI, you can check [this example](https://github.com/actions-rs/meta/blob/main/recipes/quickstart.md) for a quickstart using GitHub Actions. As Bevy has additional Linux dependencies, you should install them before building your project, [here is how Bevy is doing it](https://github.com/bevyengine/bevy/blob/cf0e9f9968bb1bceb92a61cd773478675d35cbd6/.github/workflows/ci.yml#L39). Even if you don't have many (or any) tests, setting up CI will compile check your plugin and ensure a basic level of quality.
There are some [extra fields](https://doc.rust-lang.org/cargo/reference/manifest.html) that you can add to your `Cargo.toml` manifest, in the `[package]` section:
|field|description|
|-|-|
|[`description`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-description-field)|a description of the plugin|
|[`repository`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-repository-field)|URL of the plugin source repository|
|[`keywords`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-keywords-field)|keywords for the plugin - `"bevy"` at least is a good idea here|
|[`categories`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-categories-field)|categories of the plugin - see [the full list on crates.io](https://crates.io/categories)|
|[`exclude`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-exclude-and-include-fields)|files to exclude from the released package - excluding the `assets` folder that you may have is a good idea, as well as any large file that are not needed by the plugin|
Once a crate is published to [crates.io](https://crates.io), there are two badges that you can add to your `README.md` for easy links:
