+## Configuration
+
+The plugin can be configured using
+[.npmbundlerrc global config section](https://github.com/liferay/liferay-js-toolkit/wiki/.npmbundlerrc-file-reference#config)
+or in the plugin configuration itself.
+
+In both cases the structure is the same:
+
+```json
+{
+	"resolve": {
+		"aliasFields": ["browser"]
+	}
+}
+```
+
+This resembles webpack's
+[resolve.aliasFields](https://webpack.js.org/configuration/resolve/#resolvealiasfields)
+which serves the same purpose.
+
+Normally global config is preferred, but you can leverage plugin configuration
+when you need different alias fields for different packages.
+
+The default value for `resolve.aliasFields` is `['browser']` as in webpack.
+
+Note that this plugin used to look for `unpkg` and `jsdelivr` fields too, but it
+caused problems (see https://github.com/liferay/liferay-js-toolkit/issues/365
+for more information).
+
 ## Technical Details
 
-This plugin scans `package.json` for a `browser`/`unpkg`/`jsdelivr` entry and 
-copies browser modules on top of server modules or deletes them when set to 
-`false`.
+This plugin scans `package.json` for fields defined in `resolve.aliasFields`
+and redirects aliased modules to their configured target or empties them when
+set to `false`.
 
-Please read the 
-[`browser` field specification](https://github.com/defunctzombie/package-browser-field-spec) 
+This plugin only does one part of the whole implementation of the aliases.
+Aliases implementation have two parts:
+
+1.  They redirect existing modules or provide virtual ones when seen from
+    the outside, from another package.
+
+2.  They make local requires divert to a different target.
+
+This plugin does only the 1st part. The second one is performed by
+[babel-plugin-alias-modules](https://github.com/liferay/liferay-js-toolkit/tree/master/packages/babel-plugin-alias-modules).
+
+Please read the
+[`browser` field specification](https://github.com/defunctzombie/package-browser-field-spec)
 for more information.
