+A very simple singleton object pooler for optimization. It can handle all of the object pooling during the game loading and is persistant throughout scenes
+
+Currently to get the objects from the pool you need to know the index in the pool, will be changed to either use the position or the name.
+# What is pooling? 
+It is computationally expensive to instantiate and destroy objects like bullets that get re-used a lot.
+Its a lot more effective to instantiate them all in the beginning and to keep re-using them by setting them active/false
+
+This script can act as a pooling control hub, it will create all pooled objects you need at the start and objects can be called as and when needed by other scripts.
+
+## How to setup
+1) Create a new empty GameObject
+2) Create a new script called ObjectPooler and attach it to the GameObject
+3) Replace the contents of ObjectPooler with contents of the ObjectPooler script that can be found in this repo.
+4) In the inspector, in the script component, enter the number of gameObjects you want pooled and then add their prefabs to the list.
+5) Increase Amount to Pool to at least 1. You can also check the 'Load More If None Left' box if you are unsure on how many you will need
+6) Access the Pooled Objects by using
+
+```
+GameObject GO = ObjectPooler.Instance.GetGameObject(/*Index of the Pooled Object*/);
+ //Make changes to your gameObject here
+ ```

 If you enable Load More If None Left, then if the pool runs out of the object you want, it will create a new one and add it to the pool
