+# Medusa Tutorial Structure Rules
+
+## Overview
+
+This file defines the structure and formatting requirements for creating Medusa tutorials in the `/app/how-to-tutorials/tutorials/` directory. All tutorials must follow this structure to ensure consistency and quality.
+
+## File Structure
+
+### 1. Frontmatter (Required)
+
+Every tutorial must start with YAML frontmatter containing:
+
+```yaml
+---
+sidebar_label: "Tutorial Name"  # Display name in sidebar
+tags:
+    - name: product_name         # Product tags (e.g., cart, order, customer)
+      label: "Implement Feature"
+    - server                      # Always include if server-side code
+    - tutorial                   # Always include
+    - nextjs                     # Include if storefront customization
+products:
+  - product_name                 # Array of product names used
+---
+```
+
+**Additional frontmatter options:**
+
+- `keywords`: Array of keywords for SEO (optional)
+- `ogImage`: Export for Open Graph image (optional)
+
+### 2. Imports
+
+After frontmatter, include necessary imports:
+
+- `Github`, `PlaySolid` from `@medusajs/icons` (if needed)
+- `Prerequisites`, `WorkflowDiagram`, `CardList`, `Card` from `docs-ui`
+- Other necessary components
+
+### 3. Metadata Export
+
+```typescript
+export const metadata = {
+  title: `Implement Feature Name in Medusa`,
+  // Optional: openGraph and twitter metadata
+}
+```
+
+### 4. Title Section
+
+```markdown
+# {metadata.title}
+
+In this tutorial, you'll learn how to [brief description].
+```
+
+### 5. Context Paragraph
+
+Include 1-2 paragraphs explaining:
+
+- What Medusa provides out-of-the-box
+- What the tutorial will teach
+- Context about the feature being implemented
+
+### 6. Summary Section
+
+```markdown
+## Summary
+
+By following this tutorial, you will learn how to:
+
+- Install and set up Medusa.
+- [Feature 1]
+- [Feature 2]
+- [Feature 3]
+```
+
+### 7. Visual Elements
+
+- Include diagrams/images when helpful (use Cloudinary URLs)
+- Use `WorkflowDiagram` component for workflow visualizations
+- Use `CardList` or `Card` components for GitHub links and OpenAPI specs
+
+### 8. Step Structure
+
+#### Step 1: Install a Medusa Application (Always Required)
+
+```markdown
+## Step 1: Install a Medusa Application
+
+<Prerequisites items={[
+  {
+    text: "Node.js v20+",
+    link: "https://nodejs.org/en/download"
+  },
+  {
+    text: "Git CLI tool",
+    link: "https://git-scm.com/downloads"
+  },
+  {
+    text: "PostgreSQL",
+    link: "https://www.postgresql.org/download/"
+  }
+]} />
+
+Start by installing the Medusa application on your machine with the following command:
+
+\`\`\`bash
+npx create-medusa-app@latest
+\`\`\`
+
+[Instructions about installation...]
+
+<Note title="Why is the storefront installed separately">
+
+[Explanation]
+
+</Note>
+
+<Note title="Ran into Errors">
+
+Check out the [troubleshooting guides](../../../troubleshooting/create-medusa-app-errors/page.mdx) for help.
+
+</Note>
+```
+
+#### Subsequent Steps
+
+Each step should:
+
+- Have a clear, descriptive title: `## Step N: [Title]`
+- Start with context explaining what will be done
+- Break into subsections (a, b, c) if needed
+- Include code examples with proper formatting
+- Include Notes and Tips where helpful
+- End with "Test it Out" sections when applicable
+
+### 9. Code Block Formatting
+
+#### Basic Code Block
+
+```markdown
+\`\`\`ts title="src/path/to/file.ts"
+[code]
+\`\`\`
+```
+
+#### Code Block with Highlights
+
+```markdown
+export const highlights = [
+  ["line_number", "variable_name", "Description of what this does"],
+]
+
+\`\`\`ts title="src/path/to/file.ts" highlights={highlights}
+[code]
+\`\`\`
+```
+
+#### Code Block with Collapsible Lines
+
+```markdown
+\`\`\`ts title="src/path/to/file.ts" collapsibleLines="1-10" expandButtonLabel="Show Imports"
+[code]
+\`\`\`
+```
+
+#### Badge Labels
+
+- Use `badgeLabel="Storefront" badgeColor="blue"` for storefront code
+- Use `badgeLabel="Medusa Application" badgeColor="green"` for server code
+
+#### Example
+
+```markdown
+\`\`\`ts title="src/lib/data/cart.ts" badgeLabel="Storefront" badgeColor="blue"
+[code]
+\`\`\`
+```
+
+### 10. Workflow Diagrams
+
+When documenting workflows, use the `WorkflowDiagram` component:
+
+```markdown
+<WorkflowDiagram
+  workflow={{
+    name: "workflowName",
+    steps: [
+      {
+        type: "step",
+        name: "stepName",
+        description: "Description of step",
+        link: "/references/path/to/step",
+        depth: 1
+      },
+      {
+        type: "when",
+        condition: "Condition description",
+        steps: [...],
+        depth: 1
+      }
+    ]
+  }}
+/>
+```
+
+### 11. Notes and Tips
+
+Use consistently:
+
+- `<Note>` for general notes
+- `<Note title="Title">` for titled notes
+- `<Note title="Tip">` for tips
+- `<Note title="Reminder" forceMultiline>` for reminders
+
+### 12. Links to Documentation
+
+Use the special link syntax:
+
+- `!docs!/path/to/doc` for documentation links
+- `!api!/path/to/api` for API reference links
+- `!user-guide!/path/to/guide` for user guide links
+- `!ui!/path/to/component` for UI component links
+- `!cloud!/path/to/doc` for cloud documentation
+
+### 13. Test Sections
+
+Include "Test it Out" sections after major implementations:
+
+```markdown
+### Test it Out
+
+To test out [feature], start the Medusa application:
+
+\`\`\`bash npm2yarn badgeLabel="Medusa Application" badgeColor="green"
+npm run dev
+\`\`\`
+
+[Additional testing instructions...]
+```
+
+### 14. Next Steps Section
+
+End every tutorial with:
+
+```markdown
+## Next Steps
+
+You've now implemented [feature] in Medusa. [Optional: suggest related features or improvements]
+
+If you're new to Medusa, check out the [main documentation](!docs!/learn), where you'll get a more in-depth understanding of all the concepts you've used in this guide and more.
+
+To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](../../../commerce-modules/page.mdx).
+```
+
+### 15. Optional Sections
+
+#### Troubleshooting
+
+```markdown
+### Troubleshooting
+
+If you encounter issues during your development, check out the [troubleshooting guides](../../../troubleshooting/page.mdx).
+```
+
+#### Getting Help
+
+```markdown
+### Getting Help
+
+If you encounter issues not covered in the troubleshooting guides:
+
+1. Visit the [Medusa GitHub repository](https://github.com/medusajs/medusa) to report issues or ask questions.
+2. Join the [Medusa Discord community](https://discord.gg/medusajs) for real-time support from community members.
+```
+
+## Code Organization Guidelines
+
+### File Paths
+
+- Always use absolute paths or paths relative to the workspace root
+- Use `src/` prefix for source files
+- Specify file paths clearly in code block titles
+
+### Naming Conventions
+
+- Use descriptive variable and function names
+- Follow TypeScript/JavaScript conventions
+- Use camelCase for variables and functions
+- Use PascalCase for components and classes
+
+### Code Comments
+
+- Add comments explaining complex logic
+- Use highlights arrays to explain important lines
+- Include context about why code is structured a certain way
+
+## Content Guidelines
+
+### Clarity
+
+- Write in second person ("you'll learn", "you'll create")
+- Use active voice
+- Be specific and concrete
+- Avoid jargon without explanation
+
+### Completeness
+
+- Include all necessary code
+- Explain each step thoroughly
+- Provide context for decisions
+- Include error handling where relevant
+
+### Consistency
+
+- Use consistent terminology throughout
+- Follow the same structure for similar steps
+- Use the same formatting for code blocks
+- Maintain consistent tone
+
+## Common Patterns
+
+### Module Creation Steps
+
+1. Create module directory
+2. Create data models
+3. Create module service
+4. Export module definition
+5. Add module to config
+6. Generate migrations
+
+### Workflow Creation Steps
+
+1. Create workflow steps
+2. Create workflow
+3. Create API route (if needed)
+4. Add middleware (if needed)
+5. Test
+
+### Storefront Customization Steps
+
+1. Add types/interfaces
+2. Add data fetching functions
+3. Create components
+4. Integrate into existing pages
+5. Test

+## Examples of Good Tutorial Structure
+
+### Example Step
+
+```markdown
+## Step 2: Create Custom Module
+
+In this step, you'll create a custom module to [purpose].
+
+<Note>
+
+Refer to the [Modules documentation](!docs!/learn/fundamentals/modules) to learn more.
+
+</Note>
+
+### Create Module Directory
+
+Modules are created under the `src/modules` directory. So, create the directory `src/modules/custom-module`.
+
+### Create Data Models
+
+[Explanation of data models...]
+
+\`\`\`ts title="src/modules/custom-module/models/model.ts"
+[code]

+
+## Final Notes
+
+- Always prioritize clarity and completeness
+- Include all necessary context
