FAQ

How do I showcase GitHub Actions workflows?

Use the 'Code Snippet' template with YAML syntax highlighting for workflow files. Focus on key jobs or interesting automation patterns (5-10 steps). The highlighter beautifully renders GitHub Actions syntax including jobs, steps, and action usage.

What template works best for repository announcements?

For project launches, use the 'Minimalist' or 'Banner' template with your project name and key value proposition. Add GitHub icon prominently, plus icons for your tech stack. This gives viewers immediate understanding of what the repository offers and what it's built with.

Can I create images for open source contribution guides?

Absolutely! Use 'Minimalist' template with welcoming text like 'Contributions Welcome' or show contribution workflow code. Add GitHub icon to signal open source context. For technical contribution guides, use 'Code Snippet' to show Git commands or PR workflows.

How should I represent Git tutorial content?

For Git tutorials, use GitHub branding (Git and GitHub are closely associated). Show Git commands using bash/shell highlighting, or use 'Banner' template to explain concepts. Keep command examples practical and focused on one workflow (branching, merging, rebasing, etc.).
