+## Definition
+Optionally specify a custom list of directories to copy to the `target` directory as part of the `docs generate` command. This is useful for rendering images in your repository in your project documentation.

+<Changelog>
+
+* `v0.18.0`: This configuration was introduced — see the [migration guide for 0.18.0](upgrading-to-0-18-0) for more details.
+
+</Changelog>
+
+## Default
+By default, dbt will not compile any additional files as part of `docs generate`, i.e. `analysis-paths: []`
+
+## Examples
+### Compile files in the `assets` subdirectory as part of `docs generate`
+
+<File name='dbt_project.yml'>
+
+```yml
+asset-paths: ["assets"]
+```
+
+</File>
+
+Any files included in this directory will be copied to the `target/` directory as part of `dbt docs generate`, making them accessible as images in your project documentation.
+
+Check out the full writeup on including images in your descriptions [here](/reference/resource-properties/description/#include-an-image-from-your-repo-in-your-descriptions).

+To include an image from your repository in your descriptions:
+1. Add the file in a subdirectory, e.g. `assets/dbt-logo.png`
+2. Set the [`asset-paths` config](project-configs/asset-paths) in your `dbt_project.yml` file so that this directory gets copied to the `target/` directory as part of `dbt docs generate`

-At present, it's not possible to include an image in your project and render it as part of your project documentation using the image path. This is because images are not included in the `target` directory when you execute `dbt compile`. We hope to address this in the future ([related issue](https://github.com/fishtown-analytics/dbt/issues/2072)).
