 A few changes are necessary:
 
-1. Add the definition for the node type (`GEO_NODE_*`) in the [nodes header](https://projects.blender.org/blender/blender/src/branch/main/source/blender/blenkernel/BKE_node.h).
+1. Add the definition for the node type (`GEO_NODE_*`) in the [nodes header](https://projects.blender.org/blender/blender/src/branch/main/source/blender/blenkernel/BKE_node.hh).
   - This integer is used in some places to access the node type without its string idname
 2. Add a new file with the node's implementation in the geometry nodes [folder](https://projects.blender.org/blender/blender/src/branch/main/source/blender/nodes/geometry/nodes).
   - This file initializes the node type when Blender starts. The node type contains its inputs/outputs, execute callback, and other functions.
