+**********
+ Overview
+**********
+
+Currently ScanCode.io scans the packages but doesn’t store it. This
+makes it difficult for users to maintain a reference of packages used in
+their projects, meet source redistribution obligations, or revisit
+scanned packages for future.
+
+This project enhanced ScanCode.io by adding the ability to store and
+query downloaded packages locally and re-use packages that were already
+scanned.
+
+----
+
+****************
+ Implementation
+****************
+
+The project involved the following key components and steps:

+
+   Currently ScanCode.io downloads packages but does not store them. The new archiving system stores downloaded packages on the local filesystem and allows querying them.
+
+Storage System Development:
+
+-  Created a `DownloadStore` abstract base class in `archiving.py` to
+   define the interface for managing package content and metadata
+   storage.
+
+-  Built the `LocalFilesystemProvider` class to store downloads on the
+   local filesystem, using a SHA256-based nested directory structure.
+
+-  Implemented methods for storing (`put`), retrieving (`get`), listing
+   (`list`), and searching (`find`) downloads, with metadata saved in
+   `origin-<hash>.json` files.
+
+Integration with ScanCode.io:
+
+-  Updated `pipelines/init.py` to incorporate the archiving system into
+   ScanCode.io’s pipeline workflow, ensuring downloaded packages are
+   stored during execution.
+
+-  Revised `input.py` to process package download inputs, passing
+   content, `download_url`, `download_date`, and `filename` to the
+   archiving system.
+
+User Interface Enhancements:
+
+-  Modified the project resource view to display stored package
+   information, including download URLs and dates.
+
+Validation and Testing:
+
+-  Wrote unit tests in `test_archiving.py` to verify
+   `LocalFilesystemProvider` functionality (`put`, `get`, `list`,
+   `find`), testing normal cases, edge cases (e.g., empty files), and
+   errors (e.g., duplicate origins).

+ Closing Notes
+***************
+
+During the GSoC coding period, my mentors and I had weekly meetings to
+discuss progress, challenges, and next steps. Thank you so much to my
+mentors for being there every step of the way during GSoC 2025. Your
+encouragement and insights made a huge difference in my learning
+journey.
