+## resolverConfig
+
+Override the options generated by this plugin for resolving require and import statements.
+
+While these options are passed down to [`enhanced-resolve`](https://github.com/webpack/enhanced-resolve)'s factory method, we only support a subset of the options they allow. These are documented below.
+
+The options you define here are assigned over the default options generated by the plugin.
+
+Supported options:
+
+- `resolverConfig.modules`: A list of directories to resolve modules from, can be absolute path or folder name
+
+### Example resolverConfig
+
+```json
+{ "resolverConfig": { "modules": ["node_modules", "bower_components"] } }
+```
+
+### Default resolverConfig
+
+```json
+{ "resolverConfig": {} }
+```
+
 ## convertPath
 
 If we use transpilers (e.g. Babel), perhaps the file path to a source code is never published.
