+## Mounting assets on a path
+
+:::note
+This feature requires Wrangler v3.xx.xx or later.
+:::
+
+You can mount assets on a path by creating a directory structure that mirrors the desired path.
+For example, to serve assets from `example.com/blog`, create a `blog` directory in your asset directory.
+
+<FileTree>
+- dist
+	- blog
+		- index.html
+		- posts
+			- post1.html
+			- post2.html
+</FileTree>
+
+With a Wrangler configuration file like so:
+<WranglerConfig>
+```toml
+name = "mounted-assets-example"
+main = "src/index.js"
+route = "example.com/blog/*"
+
+[assets]
+directory = "dist"
+```
+</WranglerConfig>
+
+In this example, requests to `example.com/blog` will serve the `index.html` file, and requests to `example.com/blog/posts/post1` will serve the `post1.html` file.
+
+If you have a file outside the mounted path, it will not be served. For example, if you have a `home.html` file in the root of your asset directory, it will not be served when requesting `example.com/blog/home`.
