There two ways to install this preprocessor.
You can install with **cargo** if you have [rust](https://www.rust-lang.org) installed:
```sh
cargo install mdbook-repl
```
Or you can download the **binary** from [release page](https://github.com/MR-Addict/mdbook-repl/releases). Then you can put the binary in your **PATH**.
You can check if the installation is successful by running:
```sh
mdbook-repl --version
```
