+# CFDP Manager Attribution
+
+This component implements the CCSDS File Delivery Protocol (CFDP) for F-Prime (F'). It includes both ported code from NASA's Core Flight System (cFS) CFDP application and new F' implementations.
+
+## Source Attribution
+
+Portions of this code are derived from the NASA Core Flight System (cFS) CFDP (CF) Application:
+- **Repository**: https://github.com/nasa/CF
+- **Version**: 3.0.0
+- **License**: Apache License 2.0
+- **Copyright**: Copyright (c) 2019 United States Government as represented by the Administrator of the National Aeronautics and Space Administration
+- **NASA Docket**: GSC-18,447-1
+
+## Files Ported from CF
+
+The following files are ports/adaptations from CF source code and retain the original NASA copyright:
+
+### Core Engine & Transaction Management
+- `Engine.hpp` / `.cpp` - from `cf_cfdp.c` / `cf_cfdp.h`
+- `Transaction.hpp` - from `cf_cfdp_r.h` / `cf_cfdp_s.h` / `cf_cfdp_dispatch.h`
+- `TransactionTx.cpp` - from `cf_cfdp_s.c` / `cf_cfdp_dispatch.c`
+- `TransactionRx.cpp` - from `cf_cfdp_r.c` / `cf_cfdp_dispatch.c`
+
+### Data Structures & Utilities
+- `Types/Types.hpp` - from `cf_cfdp_types.h`
+- `Utils.hpp` / `.cpp` - from `cf_utils.h` / `cf_utils.c`
+- `Channel.hpp` / `.cpp` - from channel functions in `cf_cfdp.c` / `cf_utils.c`
+- `Chunk.hpp` / `.cpp` - from `cf_chunks.h` / `cf_chunks.c`
+- `Clist.hpp` / `.cpp` - from `cf_clist.h` / `cf_clist.c`
+
+Each of these files includes the full NASA copyright notice and Apache 2.0 license text in its header.
+
+## New F-Prime Implementations
+
+The following files are new implementations for F-Prime and do not contain CF-derived code:
+
+### Integration Layer
+- `CfdpManager.hpp` / `.cpp` - F-Prime component wrapper
+- `Timer.hpp` / `.cpp` - F-Prime timer implementation
+
+### PDU Object-Oriented Implementation
+All files in the `Types/` directory are new F' serializable implementations based on the CFDP Blue Book specification (CCSDS 727.0-B-5):
+- `Types/PduBase.hpp` - Base class for all PDU types
+- `Types/PduHeader.hpp` / `.cpp` - PDU header encoding/decoding
+- `Types/MetadataPdu.hpp` / `.cpp` - Metadata PDU
+- `Types/FileDataPdu.hpp` / `.cpp` - File Data PDU
+- `Types/EofPdu.hpp` / `.cpp` - End of File PDU
+- `Types/FinPdu.hpp` / `.cpp` - Finished PDU
+- `Types/AckPdu.hpp` / `.cpp` - Acknowledge PDU
+- `Types/NakPdu.hpp` / `.cpp` - Negative Acknowledge PDU
+
+These files implement CFDP PDU encoding/decoding based on the specification rather than porting CF's C-style codec.
+
+## License
+
+This component as a whole is licensed under the Apache License 2.0. See the top-level [LICENSE.txt](../../../LICENSE.txt) for the full license text.
+
+The CF-derived portions retain their original NASA copyright and Apache 2.0 license as documented in their file headers.
