# Installation
Lune is designed to be used without a build step. You can simply load it from a CDN.
## CDN
::: code-group
```html [esm]
```
```html [jsdelivr]
```
```html [unpkg]
```
:::
> [!TIP] Production Tip
> For production, it is recommended to pin a specific version number to avoid unexpected breakage from newer versions.

## Package
You can also install Lune via your project's package manager:
::: code-group
```sh [npm]
npm install lune-js
```
```sh [yarn]
yarn add lune-js
```
```sh [pnpm]
pnpm add lune-js@latest
```
```sh [bun]
bun add lune-js
```
```sh [deno]
deno add npm:lune-js
```
:::
Then import it in your project:
```js
import { createApp } from "lune-js";
createApp().mount();
```
## Troubleshooting
### Loading Order
Always use `defer` when loading Lune in the `` to ensure the DOM is ready before Lune tries to initialize. If you put the script at the end of ``, `defer` is not strictly necessary but still good practice.
