-``from`` is regular expression and ``to``is letter. In the internal ``from`` and ``to`` are used with ``String#replace(new RegExp (from), to)``.
+### packageProp [string]
+
+Resolves property inside the `package.json' file. Generally set to either `main` or `name`. Anytime packageProp is set, the `option.replaces` transformation will be ignored.
+
+**note:** Prefer setting your project's `package.json` main property instead of using this override to better adhere to [npm docs's main spec](https://docs.npmjs.com/files/package.json#main).
+
+### appendPackageName [boolean]
+
+Appends the package name to the import path.
+
+### replaces [array] or [string]
 
-When writing multi rules, it will also be carried out transformation many times.
-For example, ``[{from: "^src/", to: "lib/"}, {from: "MyFooClass", to: "my-foo"}]`` converted as follows:
+Replaces can be either an array or string.
 
-- `` my-module/src/MyFooClass.js`` => `` my-module/lib/MyFooClass.js`` => ``my-module/lib/my-foo``
+#### replaces [string]
 
-# Install and Usage
-```sh
-npm install esdoc-importpath-plugin
+If replaces is a string, then the import path will always be that defined string.
