 ### Instancing and DotScene Plugin
 As of OGRE 1.13 a new feature has been added to the DotScene Plugin where it now accepts the static / instanced keywords for entities.
-(for more information read the [DotScene Plugin README](https://github.com/sercero/ogre/blob/master/PlugIns/DotScene/README.md)).
+(for more information read the [DotScene Plugin README](https://github.com/OGRECave/ogre/blob/master/PlugIns/DotScene/README.md)).
 
 To use this feature create a new collection (M) names as `static.<Group Name>` or `instanced.<Instance Manager Name>` and blender2ogre will automatically add the corresponding attribute to the exported entities in the Scene.
 This feature goes hand in hand with [Exporting Particle Systems](#exporting-particle-systems) to create vegetation, debris and other static objects in your scene.
