## Add to your project

First, add the following to your `Cargo.toml`:

```toml
[dependencies]
salvo-captcha = "0.1"
```

Or use [cargo-add](https://doc.rust-lang.org/cargo/commands/cargo-add.html) to add the dependency to your `Cargo.toml`:

```sh
$ cargo add salvo-captcha
```

## Usage

See the [examples](examples) directory for a complete example.

## Storage

The storage of the captcha is handled by a [`CaptchaStore`] trait. You can implement your own storage or use the [`cacache-rs`] by enabling the `cacache-storage` feature.

```toml
[dependencies]
salvo-captcha = { version = "0.1", features = ["cacache-storage"] }
```
