+# Jackify Tools Directory
+
+This directory contains utility tools bundled with Jackify for self-contained AppImage distribution.
+
+## How It Works
+
+**In Git Repository**: This directory only contains this README and .gitignore (no binaries).
+
+**During Build**: The `build_appimage_simple.sh` script downloads required tools from their official sources.
+
+**In AppImage**: Tools are bundled for self-contained distribution (users don't need to install dependencies).
+
+## Tools Downloaded During Build
+
+### winetricks
+- **Source**: https://github.com/Winetricks/winetricks
+- **License**: LGPL v2.1
+- **Purpose**: Wine prefix configuration and Windows component installation
+- **Downloaded from**: GitHub master branch (latest version)
+
+### cabextract
+- **Source**: https://github.com/kyz/cabextract
+- **License**: GPL v3
+- **Purpose**: Microsoft Cabinet file extraction
+- **Downloaded from**: GitHub releases (v1.11)
+
+### 7-Zip (7z / 7zz)
+- **Source**: https://www.7-zip.org/
+- **License**: GNU LGPL + unRAR restriction
+- **Purpose**: Archive extraction and compression
+- **Downloaded from**: Official 7-Zip website
+
+### lz4
+- **Source**: System package (copied from /usr/bin/lz4)
+- **License**: BSD 2-Clause
+- **Purpose**: Fast compression for TTW installer patch decompression
+- **Note**: Copied from build system, not downloaded
+
+## Why Not Store in Git?
+
+1. **Repository Size**: Binaries total ~11MB, bloating git history
+2. **Updates**: Tools update independently of Jackify code
+3. **Professional Practice**: Industry standard separates source code from build artifacts
+4. **Licensing**: Clear separation between our code and third-party binaries
+
+## For Developers
+
+When building locally with `./build_appimage_simple.sh`, these tools are automatically downloaded.
+
+If build fails to download tools, the script will attempt to use system versions as fallback.
+
+See `THIRD_PARTY_NOTICES.md` in project root for complete licensing information.
