+
+The CSS and web font files to easily self-host the “Hack-ZeroSlash” font. Please visit the main [Fontsource website](https://fontsource.org/fonts/hack-zeroslash) to view more details on this package.
+
+## Quick Installation
+
+Fontsource offers multiple methods to import the CSS, including using a bundler like Vite or using SASS. You can find full documentation [here](https://fontsource.org/docs/getting-started/introduction).
+
+```javascript
+npm install @fontsource/hack-zeroslash
+```
+
+Within your app entry file or site component, import it in.
+
+```javascript
+import "@fontsource/hack-zeroslash"; // Defaults to weight 400
+import "@fontsource/hack-zeroslash/400.css"; // Specify weight
+import "@fontsource/hack-zeroslash/400-italic.css"; // Specify weight and style
+```
+
+Supported variables:
+- Weights: `[400,700]`
+- Styles: `[normal,italic]`
+- Subsets: `[latin]`
+
+> Note: `italic` may not be supported by all fonts. To learn more about what weights and styles are supported, please visit the [Fontsource website](https://fontsource.org/fonts/hack-zeroslash).
+
+Finally, you can reference the font name in a CSS stylesheet, CSS Module, or CSS-in-JS.
+
+```css
+body {
+  font-family: "Hack-ZeroSlash";
+}
+```
+
+## Licensing
+Always make sure to read the license for each font you use. Most of the fonts in the collection use the SIL Open Font License, v1.1. Some fonts use the Apache 2 license. The Ubuntu fonts use the Ubuntu Font License v1.0.
