When you open a skill from the skills hub, you enter its workspace. This is where all the learning content lives: documentation, code examples, diagrams, and progress tracking for that skill. ## What is inside a workspace ### Knowledge base Each workspace has a full knowledge base with structured documentation on the topic. You can search within it and browse by section. ### Code examples Real code samples with syntax highlighting. You can read, copy, and study the code directly in the workspace. ### Interactive code editor Write and experiment with code inside the workspace. Pro users get unlimited code highlights and annotations. * **Free:** 3 highlights per workspace * **Pro:** unlimited highlights ### Career tree visualization A visual diagram showing how this skill fits into the bigger picture: what it leads to, what depends on it, and where it sits in a career path. ### Iceberg diagram Shows skill depth from beginner to expert level. The surface layer covers basics. Deeper layers show advanced topics that take more time and experience to learn. ### Notes and bookmarks Save personal notes within any workspace. Bookmark sections you want to revisit later. ### Skill completion tracking The workspace tracks which sections you have completed. Your progress syncs across devices and shows up on your dashboard. ### Export Download workspace content for offline study. Open a workspace from the skills hub or directly from a career path page.
