+# Bzip2
+
+Bzip2 is a freely available, patent-free, high-quality data compressor. It provides significantly better compression than traditional gzip compressors, especially for text files, by using the Burrows-Wheeler block sorting text compression algorithm combined with Huffman coding.
+
+## Features
+
+- High compression ratio, particularly effective on text files
+- Patent-free implementation
+- Cross-platform compatibility
+- Recovery tool for damaged compressed files
+- Standard Unix-style command-line interface
+
+## Included Programs
+
+- **bzip2**: Compresses files using the Burrows-Wheeler algorithm
+- **bunzip2**: Decompresses bzip2 compressed files (link to bzip2)
+- **bzcat**: Decompresses files to standard output
+- **bzip2recover**: Attempts to recover data from damaged bzip2 files
+- **bzgrep, bzegrep, bzfgrep**: Search within bzip2 compressed files
+- **bzdiff, bzcmp**: Compare bzip2 compressed files
+- **bzmore, bzless**: View bzip2 compressed files
+
+## Library
+
+- **libbz2**: Shared library providing bzip2 compression and decompression functions for other applications
+
+## Installation Notes
+
+This package follows the Linux From Scratch installation guidelines, including:
+- Installation of shared library with proper symlinks
+- Relative symbolic links for portability
+- Documentation installation
+- Removal of unnecessary static library
+
+## Usage Examples
+
+```bash
+# Compress a file
+bzip2 myfile.txt
+
+# Decompress a file
+bunzip2 myfile.txt.bz2
+
+# View compressed file without decompressing
+bzcat myfile.txt.bz2
+
+# Search within compressed files
+bzgrep "pattern" logfile.bz2
