Unfortunately updating the project template doesn't auto fill all proper information back into the menu.
So some manual work is required.
- If files are moved/renamed or added/removed make sure the project is up to date with these changes
- Do not include .mex files in the project!
- Don't forget to up the version if required
- From the 'PROJECT' tab in Matlab, from the 'Share' dropdown menu select 'Simulink Template'
- Change the Author to GOcontroll
- Set the image to GOcontroll.png which is located in the project
- It might show a warning about the .mex files which aren't included, check if this is the case, if so 'continue anyway'
