+# LZ4
+
+LZ4 is a lossless compression algorithm, providing compression speed greater than 500 MB/s per core. It features an extremely fast decoder, with speed in multiple GB/s per core. LZ4 can work with Zstandard to allow both algorithms to compress data faster.
+
+## Features
+
+- Extremely fast compression (500+ MB/s per core)
+- Very fast decoder (multi-GB/s per core)
+- Lossless compression algorithm
+- Compatible with Zstandard
+- Streaming compression support
+- Frame format for integrity checking
+
+## Installed Programs
+
+- `lz4` - Compresses or decompresses files using the LZ4 format
+- `lz4c` - Compresses files using the LZ4 format (link to lz4)
+- `lz4cat` - Lists the contents of a file compressed using the LZ4 format (link to lz4)
+- `unlz4` - Decompresses files using the LZ4 format (link to lz4)
+
+## Installed Library
+
+- `liblz4.so` - The library implementing lossless data compression, using the LZ4 algorithm
+
+## Usage Examples
+
+### Basic Compression
+```bash
+# Compress a file
+lz4 file.txt file.txt.lz4
+
+# Decompress a file
+lz4 -d file.txt.lz4 file.txt
+```
+
+### Using with pipes
+```bash
+# Compress output of a command
+tar -cf - /path/to/directory | lz4 > archive.tar.lz4
+
+# Decompress to pipe
+lz4 -d archive.tar.lz4 | tar -xf -
+```
+
+### Using the library
+The LZ4 library can be used in C/C++ applications to provide fast compression and decompression capabilities.
+
+## Performance
+
+LZ4 is designed for speed-critical applications where compression ratio is secondary. It offers:
+
+- Compression speeds over 500 MB/s per core
+- Decompression speeds over 1 GB/s per core
+- Trade-off between compression speed and ratio
