-## ✅ Why Strings-LE
+Extract strings from **any file format** — JSON, CSV, ENV, YAML, TOML — in one click. No regex. No scripts. Just results.
 
-**Modern projects scatter text everywhere** — APIs, configs, CSVs, and locale files across both native and web. Keeping those strings consistent is still a slow, manual grind.

-**Strings-LE makes extraction effortless.**  
-It smartly pulls out only the **true user-visible strings** (never numbers, IDs, or raw values) and gives you a clean, ordered set of text that’s ready for production.
+String-LE intelligently identifies **user-visible text** while filtering out numbers, IDs, URLs, and technical noise. Get a clean, ordered set of strings ready for i18n, documentation, or validation.

 ## 🔧 Troubleshooting
 
-### Common Issues
-
-**Extension not detecting strings**
-
-- Ensure file is saved and has a supported extension (.json, .yaml, .csv, .toml, .ini, .env)
-- Check that the file contains user-visible strings (not just IDs or numbers)
-- Try reloading VS Code window (`Ctrl/Cmd + Shift + P` → "Developer: Reload Window")
-
-**Performance issues with large files**
-
-- Files over 50MB may take longer to process
-- Enable `string-le.csv.streamingEnabled: true` for CSV files
-- Consider using `string-le.dedupeEnabled: false` to reduce processing time
-- Disable sorting with `string-le.sortEnabled: false` for faster extraction
-
-**Strings not appearing in results**
+**Not detecting strings?**  
+Ensure file is saved with supported extension (.json, .yaml, .csv, .toml, .ini, .env)
 
-- Verify the content contains user-visible strings (not IDs, numbers, or technical values)
-- Check if strings are inside comments or special sections
-- Ensure strings are properly quoted in the source file
-- Some formats may require specific parsing settings
+**Large files slow?**  
+Enable CSV streaming: `string-le.csv.streamingEnabled: true`
 
-**CSV streaming issues**
-
-- Ensure CSV has proper headers for column selection
-- Check that `string-le.csv.streamingEnabled` is enabled
-- Verify CSV delimiter is standard (comma, semicolon, tab)
-- Large CSV files may require streaming to avoid memory issues
-- Multi-line strings in CSV may not be fully supported
-
-**Deduplication problems**
-
-- Enable `string-le.dedupeEnabled: true` for automatic deduplication
-- Check that similar strings are not being incorrectly merged
-- Some strings may appear different but are actually duplicates
-- Case sensitivity may affect deduplication results
-
-**Sorting issues**
-
-- Enable `string-le.sortEnabled: true` for automatic sorting
-- Sorting applies to final strings, not their original positions
-- Locale-specific sorting may vary by system settings
-- Some special characters may affect sort order
-
-**Extension crashes or freezes**
-
-- Check VS Code version compatibility (requires 1.70.0+)
-- Disable other string-related extensions temporarily
-- Check Output panel → "String-LE" for error messages
-- Consider reducing file size or using streaming mode
-
-### Getting Help
-
-- Check the [Issues](https://github.com/nolindnaidoo/string-le/issues) page for known problems
-- Enable telemetry logging: `string-le.telemetryEnabled: true`
-- Review logs in Output panel → "String-LE"
-- See [`TROUBLESHOOTING.md`](docs/TROUBLESHOOTING.md) for detailed guidance
