Documentation Reading Pattern

When reading documentation:

1. Find the right file: Match topic to documentation file
2. Read the overview: Understand the concept
3. Extract code examples: Copy exact patterns
4. Note configuration options: Review available settings
5. Check best practices: Apply security and performance tips

Example Usage

Looking up PostgreSQL Configuration

1. Navigate to 05-databases.md
2. Find PostgreSQL section
3. Extract:
   • Image version
   • Environment variables
   • Health check configuration
   • Volume setup
   • Network configuration

Looking up Network Configuration

1. Navigate to 04-networking.md
2. Find relevant section (bridge, external, internal)
3. Extract:
   • Network definition syntax
   • Service network configuration
   • DNS resolution patterns

Output

After reading documentation, provide:

1. Exact configuration pattern from docs
2. Required settings
3. Optional configurations
4. Best practices noted
5. Security considerations
