 # ScriptableObjectMultiSelectDropdown
-Multi Select Dropdown for ScriptableObjects
+ScriptableObjectMultiSelectDropdown is an attribute for the Unity Inspector.
+It is used for showing ScriptableObjects which are created in your project, in dropdown menu and select multiple of them in Inspector.
+
+# Usage Example
+1. Clone this repository or download the latest [release package available](https://github.com/ATHellboy/ScriptableObjectMultiSelectDropdown/releases) (There isn't an example folder in `.unitypackage`).
+
+2. Create `ScriptableObject` class which you  want to create specified objects by that.
+
+```cs
+using UnityEngine;
+
+[CreateAssetMenu(menuName = "Create Block")]
+public class Block : ScriptableObject
+{
+    // Some fields
+}
+```
+
+3. Put those created ScriptableObjects in `Resources` folder.

+4. Use `ScriptableObjectMultiSelectDropdown` attribute by setting type of specified ScriptableObject derived class and optional grouping  (Default grouping is None) like this in `MonoBeahviour` or `ScriptableObject` derived classes.
+
+**MonoBehavior**
+
+```cs
+using ScriptableObjectMultiSelectDropdown;
+using UnityEngine;
+
+public class BlockManager : MonoBehaviour
+{
+    // Without grouping (default is None)
+    [ScriptableObjectMultiSelectDropdown(typeof(Block))]
+    public ScriptableObjectReference firstTargetBlocks;
+    // By grouping
+    [ScriptableObjectMultiSelectDropdown(typeof(Block), grouping = ScriptableObjectGrouping.ByFolder)]
+    public ScriptableObjectReference secondTargetBlocks;
+}
+```

+using ScriptableObjectMultiSelectDropdown;
+
+[CreateAssetMenu(menuName = "Create Block Manager Settings")]
+public class BlockManagerSettings : ScriptableObject
+{
+    // Without grouping (default is None)
+    [ScriptableObjectMultiSelectDropdown(typeof(Block))]
+    public ScriptableObjectReference firstTargetBlocks;
+    // By grouping
