# bevy_terminal_dialog
> [!WARNING]
> This library is highly experimental and not intended for use by literally anyone ever. I will eventually clean this readme up, but for now don't worry about it.
## Compatibility
| Crate Version | Bevy Version |
|--- |--- |
| 0.1 | 0.14 |
## Installation
If enough people (like literally 1 person) want this on crates.io I'll consider putting it up there, but for now just add the GitHub URL to your `Cargo.toml`:
```toml
[dependencies.bevy_terminal_dialog]
git = "https://github.com/exvacuum/bevy_terminal_dialog"
```
