# Porting Classic Core Skills

Existing Mycroft skills are largely compatible with the Mark II running Dinkum, but some modifications are necessary. Most notably the use of [Sessions](/mark-ii/differences-to-classic-core/sessions.md). 

To help Skill developers port existing Skills, as well as develop new ones, we will be creating a range of documentation, tools and guides.  

The following are step-by-step examples to demonstrate everything you need to modify a Classic Core Skill and get it running in Dinkum.

1. [The Basics -- Porting Hello World Skill](/mark-ii/differences-to-classic-core/porting-classic-core-skills/porting-the-hello-world-skill.md)
2. Displaying a GUI page (coming soon)
3. Handling prompts and responses (coming soon)
