 - `test.sh`: Runs various tests against MetaCall
 - `./tests`: Includes language specific tests
 
+## Implementation
+
+This brew formulae compiles MetaCall core for ARM64 and AMD64. The installation process has been optimized to install the dependencies in a dynamic way.
+
+- Enhanced Python setup process
+    - Support for detecting Python version and location dynamically.
+    - Improved handling of Python paths for both macOS and Linux systems.
+
+- Refined NodeJS installation
+    - Installs node executable and other shared libraries separately instead of a brew dependency
+    - Bash completion for NPM
+
+- Enhanced Metacall launcher:
+    - Added more robust path detection for metacallcli based on the dsitributable type
+
+The final distributable is generated using a Homebrew extension [`brew-pkg`](https://github.com/metacall/brew-pkg). It generates a installable `.pkg` and a portable `.tgz` file. The fork includes some extra features which have been described below.
+
+1. **Recursive library patching**: The function recursively processes linked libraries.
+
+2. **Dynamic linking**: Uses `@executable_path` to create relative paths for dynamic linking.
+
+3. **ELF file validation**: Checks if the target binary is a valid ELF (Executable and Linkable Format) file.
+
+4. **Library dependency analysis**: Uses `otool -L` to identify linked libraries for the given binary.
+
+5. **Path filtering**: Filters library paths to only process those within the specified prefix path.
+
+6. **Relative path calculation**: Computes relative paths between the binary and its linked libraries.
+
+7. **Library path updating**: Uses `install_name_tool` to update library paths in the binary.
+
 ## Usage
 
 MetaCall supports `ARM64` and `AMD64` architectures at the moment.
