+# PCR Simulation and Barcode Extraction Module
+
+This Go package (`obingslibrary`) provides configuration-driven tools for **PCR simulation and barcode extraction** from NGS libraries.
+
+## Core Concepts
+
+- `Options`: A fluent configuration object for customizing behavior via functional setters.
+- Default options are defined in `MakeOptions`, supporting:
+  - Error handling (`discardErrors`)
+  - Mismatch/indel tolerance via `allowedMismatch` and `allowsIndel`
+  - Parallelization (`parallelWorkers`) and batching control (`batchSize`)
+  - Optional progress tracking (`withProgressBar`)
+
+## Key Functionalities
+
+- **Barcode Extraction**:
+  - `ExtractBarcodeSlice`: Extracts barcodes from a slice of sequences using the NGS library, applying configured error handling and alignment parameters.
+  - `ExtractBarcodeSliceWorker`: Returns a reusable worker function for batch processing (e.g., in pipelines or parallel workers).
+
+- **Compilation Step**:
+  - `ngslibrary.Compile(...)` prepares internal indexing based on mismatch/indel settings before extraction.
+
+- **Error Handling**:
+  - If `discardErrors` is true (default), sequences causing extraction errors are filtered out.
+  - Alternatively, error-containing reads can be retained or logged via `OptionUnidentified`.
+
+## Design Highlights
+
+- Uses the *option pattern* for extensibility and clean API.
+- Integrates with default settings from `obidefault` (e.g., parallelism, batch size).
+- Designed for both direct use and integration into concurrent workflows.
