 The [blog collection](/src/content/blog/) is setup to support MDX blog posts with all images being pulled from the collection's [\_images directory](/src/content/blog/_images/). Images should be a `webp` format of a reasonable width, something in the 800-1600px range is ideal.
 
 Blog post cover and social images are set as frontmatter properties and should point reference the `_images` directory, ex: `coverImage: "/src/content/blog/_images/post-1/cover.webp"`.

+### Large Static Assets
+
+Cloudflare Workers has a 25 MB per-file size limit for static assets. Files that exceed this limit are hosted on an R2 bucket and served via `site-assets.astro.build`.
+
+To upload a new large asset:
+
+1. Install [Wrangler](https://developers.cloudflare.com/workers/wrangler/) if you haven't already:
+   ```sh
+   pnpm add -g wrangler
+   ```
+
+2. Upload the file to the `site-assets` R2 bucket:
+   ```sh
+   wrangler r2 object put site-assets/<path> --file <local-file> --content-type <mime-type>
+   ```
+   For example:
+   ```sh
+   wrangler r2 object put site-assets/blog/launch-video.mp4 --file ./launch-video.mp4 --content-type video/mp4
+   ```
+
+3. Reference the file using `https://site-assets.astro.build/<path>` in your source code.
