## Installation

You can install this project from Hackage using `cabal` or from source. See [INSTALLATION] for details.

## Basic Usage

For full usage, please see the [manual].

### Starting the TUI

GHCiTUI runs a repl in the current directory by default.

```bash
$ cd your/cabal/project/root/directory
$ ghcitui
```

You can specify another directory with the `-C <DIR>` flag.

```bash
$ ghcitui -C some/other/directory
```

### Quitting the TUI

Press `<ESC>` or `q` while in the code viewport panel to quit. While not in the
