 ### Module Responsibilities
 
 - **`types.zig`**: Contains `ManEntry`, `ManEntryList`, and `SearchConfig` structures
 - **`parser.zig`**: Handles command line argument parsing, validation, and help text
-- **`search.zig`**: Manages man page searching, parsing, and path resolution
-- **`display.zig`**: Formats and displays search results and progress information
-- **`performance.zig`**: Essential optimizations for fast string operations and I/O
-- **`main.zig`**: Orchestrates the program flow and coordinates between modules
-
-## Performance Features
-
-The tool is optimized for speed while maintaining simplicity:
-
-- **Early filtering**: Section filtering happens during parsing for better performance
-- **Efficient I/O**: Optimized buffer sizes and reading strategies
-- **Fast string operations**: Optimized string comparisons for common cases
-- **Memory efficiency**: Exponential growth strategy for collections
-- **POSIX optimization**: Common man page directories checked first
+- **`search.zig`**: Manages man page searching and keyword matching
 
 ## Usage
 
 ### Basic Search
 ```bash
 manwhere sleep              # Find all man pages mentioning "sleep"
+# Output:
+# sleep
+# appsleepd
+```
+
+### Interactive Selection with fzf
+```bash
+manwhere sleep | fzf | xargs man    # Select and open a man page
 ```
 
 ### Section Filtering
 ```bash
 manwhere -s 1 sleep         # Find only commands (section 1)
 manwhere --section 3 sleep  # Find only library functions (section 3)
-```
-
-### Verbose Mode
-```bash
-manwhere -v sleep           # Show timing and processing details
-manwhere --verbose sleep    # Same as above
-```
-
-### Path Resolution
-```bash
-manwhere --paths sleep      # Show file paths (slower but more detailed)
-```
-
-### Combined Options
-```bash
-manwhere -v --paths -s 1 sleep  # Verbose, with paths, section 1 only
+manwhere -s 1 -s 3 sleep    # Search sections 1 and 3
 ```
 
 ### Help
 ```bash
 manwhere -h                 # Show help message
-manwhere --help             # Same as above
 ```

 ## Performance
 
-The tool is designed to be fast and efficient:
+- **Typical search time**: ~10ms
+- **Memory usage**: Minimal (streams results)
+- **No database required**: Scans filesystem directly
 
-- **Typical search time**: 700-800ms for common keywords
-- **Section filtering**: 20-30% faster than searching all sections
-- **Path resolution**: Adds ~200-300ms for detailed results
-- **Memory usage**: ~8-12MB for typical searches
-- **Scalability**: Handles large result sets efficiently
+## Design Philosophy
+
+This tool follows Unix philosophy: do one thing well and compose with other tools.
+
+- **No interactive mode**: Use `fzf`, `dmenu`, or similar tools
+- **No descriptions**: Fast name-only output
+- **No verbose mode**: Silent operation for scripts
+- **No formatted output**: Plain text for easy parsing
+
+## Example Workflows
+
+### Find and open a man page
+```bash
+manwhere printf | fzf | xargs man
+```
+
+### Quick lookup with preview
+```bash
+manwhere sleep | fzf --preview 'man {}'
+```
+
+### Scripting
+```bash
+# Find all SSL-related functions
+manwhere ssl | while read name; do
+    man 3 "$name" 2>/dev/null && break
+done
+```
 
 ## POSIX Compatibility
 
@@ -130,33 +124,6 @@ Works reliably on:
 - **macOS**: Standard paths plus Homebrew (`/opt/homebrew/share/man`) and MacPorts (`/opt/local/share/man`)
 - **Other Unix-like systems**: Standard man page directory structures
 
-## Error Handling
-
-The program provides clear error messages for:
-- Invalid command line options
-- Missing required arguments
-- Invalid section numbers
-- Multiple keywords (not supported)
-- Search failures
-
-## Why Simple and Fast?
-
-This tool prioritizes:
-1. **Reliability** - Works consistently across POSIX systems
-2. **Speed** - Essential optimizations without complexity
-3. **Simplicity** - Easy to understand, maintain, and debug
-4. **POSIX compatibility** - No platform-specific dependencies
-5. **Performance** - Fast enough for daily use without over-engineering
-
-## Contributing
-
-The simple structure makes it easy to:
-- Add new search features
-- Implement different output formats
-- Add support for additional platforms
-- Extend the man page section detection
-- Optimize performance further
