+# Template Format Conventions
+
+Templates in the BMAD method use standardized markup for AI processing. These conventions ensure consistent document generation.
+
+## Template Markup Elements
+
+- **{{placeholders}}**: Variables to be replaced with actual content
+- **[[LLM: instructions]]**: Internal processing instructions for AI agents (never shown to users)
+- **REPEAT** sections: Content blocks that may be repeated as needed
+- **^^CONDITION^^** blocks: Conditional content included only if criteria are met
+- **@{examples}**: Example content for guidance (never output to users)
+
+## Processing Rules
+
+- Replace all {{placeholders}} with project-specific content
+- Execute all [[LLM: instructions]] internally without showing users
+- Process conditional and repeat blocks as specified
+- Use examples for guidance but never include them in final output
+- Present only clean, formatted content to users
+
+## Critical Guidelines
+
+- **NEVER display template markup, LLM instructions, or examples to users**
+- Template elements are for AI processing only
+- Focus on faithful template execution and clean output
+- All template-specific instructions are embedded within templates
