### The `ol` package

The recommended way to use OpenLayers is to work with the `ol` package.

To add OpenLayers to an existing project, install the latest with `npm`:

    npm install ol

If you are starting a new project from scratch, see the quick start docs for more information.

### Hosted build for development

If you want to try out OpenLayers without downloading anything (not recommended for production), include the following in the head of your html page:

    <script src="https://cdn.jsdelivr.net/npm/ol@v10.9.0/dist/ol.js"></script>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/ol@v10.9.0/ol.css">

The full build of the library does not include all dependencies: the `geotiff` and `ol-mapbox-style` packages are omitted. If you use these, you'll need to add additional script tags.
