+## Configuration options
+
+Below options can be specified under `with:` for the `unity-builder` action.
+
+#### projectPath
+
+Specify the path to your Unity project to be built.
+The path should be relative to the root of your project.
+
+_**required:** `false`_
+_**default:** `<your project root>`_
+
+#### unityVersion
+
+Version of Unity to use for building the project.
+
+_**required:** `false`_
+_**default:** `2019.2.1f11`_
+
+#### targetPlatform
+
+Platform that the build should target.
+
+_**required:** `true`_
+
+#### buildName
+
+Name of the build.
+
+_**required:** `false`_
+_**default:** `testBuild`_
+
+#### buildsPath
+
+Path where the builds should be stored.
+
+In this folder a folder will be created for every targetPlatform.
+
+_**required:** `false`_
+_**default:** `build`_
+
+#### buildCommand
+
+Custom command to run your build.
+
+There are two conditions for a custom buildCommand:
+
+- Must reference a valid path to a `static` method.
+- The class must reside in the `Assets/Editor` directory.
+
+_**example:**_
+
+```yaml
+- uses: webbertakken/unity-builder@master

+```
+
+_**required:** `false`_
+_**default:** Built-in script that will run a build out of the box._
