[Lire ceci en français](README_fr.md)

A PHP Web interface for generating QR codes.

## Demo

A LibreQR instance is available at <https://qr.antopie.org>.

## Installation

### Generic

Just place this source code in a Web server with PHP.

`wget https://code.antopie.org/miraty/libreqr/archive/1.3.0.zip`

GD extension is required.

`apt install php7.3-gd`

LibreQR need writing rights on the `css/` directory.

```
chown -R www-data:www-data /var/www/libreqr/css
chmod -R 600 /var/www/libreqr/css
```

#### Security hardening

Your HTTP server can reply the following headers:
```
Content-Security-Policy: default-src 'none'; img-src 'self' data:; style-src 'self'; frame-ancestors 'none'; form-action 'self';
Referrer-Policy: no-referrer
```

### YunoHost

There is [a package](https://code.antopie.org/miraty/qr_ynh/) for [YunoHost](https://yunohost.org/).

For historical reasons, LibreQR is technically named `qr` in YunoHost.

You can install it from the WebAdmin or with this command :

```
sudo yunohost app install qr
```

## Themes

Themes are located in `themes/*`, the default theme is in `themes/libreqr/`.

You can customize your LibreQR instance look by changing the colors in `theme.php`, the logo in `logo.less` or the icons in `icons/<size>.png` (then list the sizes in `theme.php`).
