## Courses
- [Start here: your first AI-built Roblox game](https://robloxvibecoders.com/courses/start-here/): Free. Connect an AI agent to Roblox Studio, prompt it to build a working coin-collector, and learn the playtest-and-fix loop every vibecoder uses.
- [Pro setup: Rojo, Git and AI that reads your code](https://robloxvibecoders.com/courses/pro-setup/): Free. Move your scripts out of Studio into real files so your AI can read the whole project, Git can undo its mistakes, and linters catch bugs before you playtest.
- [Vibe-code a simulator, start to finish](https://robloxvibecoders.com/courses/simulator-start-to-finish/): Paid skill course. Plan, build and publish a complete simulator with AI. Covers the core loop, saving, upgrades, rebirths, pets and a launch checklist, with the prompts used at every step.
- [Monetization players don't hate](https://robloxvibecoders.com/courses/monetization-players-like/): Paid skill course. Design game passes, developer products and subscriptions that earn without making players feel cheated, then measure what works with real analytics.
- [UI that looks pro, built with AI](https://robloxvibecoders.com/courses/pro-ui-with-ai/): Paid skill course. Get AI to build clean, consistent Roblox UI that scales from phone to PC, with a component system so every new screen matches the last one.
