+This module, `swagger-ui-dist`, exposes Swagger-UI's entire dist folder as a dependency-free npm module.
+Use `swagger-ui` instead, if you'd like to have npm install dependencies for you.
 
 `SwaggerUIBundle` and `SwaggerUIStandalonePreset` can be imported:
 ```javascript
-  import { SwaggerUIBundle, SwaggerUIStandalonePreset } from 'swagger-ui-dist'
+  import { SwaggerUIBundle, SwaggerUIStandalonePreset } from "swagger-ui-dist"
+```
+
+To get an absolute path to this directory for static file serving, use the exported `getAbsoluteFSPath` method:
+
+```javascript
+const swaggerUiAssetPath = require("swagger-ui-dist").getAbsoluteFSPath()
+
+// then instantiate server that serves files from the swaggerUiAssetPath
 ```
 
 For anything else, check the [Swagger-UI](https://github.com/swagger-api/swagger-ui) repository.
