 # Adding Functionality
 
-1. Rename template_rocker/rocker_extension.py and the class inside to something more appropriate
+1. Rename template_rocker/new_rocker_extension.py and the class inside to something more appropriate
 2. Update the extension entrypoint in `pyproject.toml` 
 
     `[project.entry-points."rocker.extensions"]`
 
-    `rocker_extension = "template_rocker.rocker_extension:NewRockerExtension"`
-3. Add/update the docker snippets in the templates folder.  Officially the extension is supposed to be .Dockerfile.em to indicate its passed to the empy library, but I have left them as .Dockerfile as I get Dockerfile highlighting out of the box that way. 
-4. Develop your extension.  I find that using `pip install -e .` and running the extension with rocker on my host system is the easiest way to get started.  
+    `new_rocker_extension = "template_rocker.new_rocker_extension:NewRockerExtension"`
+
+
+    e.g.:
+    `lazygit = "lazygit_rocker.lazygit_rocker:LazygitExtension"`
+
+
+3. Update the `get_name()` function in the extension class. e.g. Updating the name to `lazygit` would mean that it would be activated by passing --lazygit to rocker
