+## Serving assets from a custom path
+
+:::note
+This feature requires Wrangler v3.98.0 or later.
+:::
+
+Like with any other Worker, [you can configure a Worker with assets to run on a path of your domain](/workers/configuration/routing/routes/).
+Assets defined for a Worker must be nested in 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.
+
+{/* prettier-ignore */}
+<FileTree>
+- dist
+	- blog
+		- index.html
+		- posts
+			- post1.html
+			- post2.html
+</FileTree>
+
+With a Wrangler configuration file like so:
+
+<WranglerConfig>
+```toml
+name = "assets-on-a-path-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 configured 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`.
+However, if needed, these files can still be manually fetched over [the binding](/workers/static-assets/binding/#binding).
