+# Homebrew Formula for needs
+
+This directory contains Homebrew formulas for the `needs` CLI tool.
+
+## Files
+
+- `needs.rb` - Development formula that builds from the current master branch
+- `needs-release.rb` - Production formula template for use with GitHub releases
+
+## Usage
+
+### For Development/Testing
+
+The `needs.rb` formula builds from the current master branch and is suitable for development and testing:
+
+```bash
+# Install directly from the local formula
+brew install --build-from-source ./needs.rb
+
+# Or if you want to test the formula
+brew install --formula ./needs.rb
+```
+
+### For Production Use
+
+The `needs-release.rb` formula is designed for use with proper GitHub releases:
+
+1. Create a GitHub release with a tag (e.g., `v0.6.0`)
+2. Calculate the SHA256 hash of the release tarball
+3. Update the `sha256` field in the formula
+4. Submit to homebrew-core or create your own tap
+
+## Platform Support
+
+Both formulas work on:
+- **macOS**: Intel and Apple Silicon
+- **Linux**: x86_64 (via Homebrew on Linux)
+
+## Dependencies
+
+- **Rust**: Required at build time to compile the Rust source code
+- **Cargo**: Comes with Rust and is used for building
+
+## Installation Process
+
+The formula:
+1. Downloads the source code
+2. Uses `cargo install` to build and install the binary
+3. Places the binary in the appropriate Homebrew bin directory
+
+## Testing
+
+The formula includes comprehensive tests that verify:
+- Binary installation
+- Help text display
+- Version output
+- Basic functionality with common binaries
+- Multi-binary checking
+
+## Usage After Installation
+
+Once installed via Homebrew, you can use `needs` from anywhere:
+
+```bash
+# Check if specific binaries are available
+needs git cargo rust
+
+# Check without version retrieval (faster)
+needs --no-versions git cargo rust
+
+# Quiet mode (exit codes only)
+needs --quiet git cargo rust
+
+# Show full version strings
+needs --full-versions git cargo rust
+
+# Use a needsfile
+echo "git\ncargo\nrust" > needsfile
+needs
+```
+
+## Troubleshooting
+
+If you encounter issues:
+
+1. **Build fails**: Ensure you have Rust installed (`brew install rust`)
+2. **Binary not found**: Check if Homebrew's bin directory is in your PATH
+3. **Permission issues**: Make sure you have write permissions to Homebrew directories
+
+## Contributing
+
+To update the formula:
+1. Update the version in `Cargo.toml`
+2. Update the version in the formula file
+3. If using releases, update the URL and SHA256 hash
+4. Test the formula locally before submitting
+
+## Future Improvements
+
+- Add support for precompiled binaries once GitHub releases with assets are available
+- Consider creating a homebrew tap for easier distribution
+- Add support for different installation options (with/without version-retrieval feature)

+# Installing needs via Homebrew
+
+This guide explains how to install the `needs` CLI tool using Homebrew on both macOS and Linux.
+
+## Prerequisites
+
+- **Homebrew**: Install from [brew.sh](https://brew.sh/)
+- **Rust**: Will be automatically installed by Homebrew as a build dependency
+
+## Installation Options
+
+### Option 1: Install from Local Formula (Current)
+
+Since the project doesn't have GitHub releases yet, you can install directly from the local formula:
+
+```bash
+# Clone the repository
+git clone https://github.com/NQMVD/needs.git
+cd needs
+
+# Install using the local formula
+brew install --build-from-source ./needs.rb
+```
+
+### Option 2: Install from GitHub (Future)
+
+Once GitHub releases are available, you can install directly:
+
+```bash
+# This will work once releases are published
+brew install https://raw.githubusercontent.com/NQMVD/needs/master/needs-release.rb
+```
+
+### Option 3: Create a Homebrew Tap (Recommended for Distribution)
+
+For easier distribution, consider creating a Homebrew tap:
+
+```bash
+# Create a tap repository
+brew tap NQMVD/needs https://github.com/NQMVD/homebrew-needs
+
+# Install from the tap
+brew install needs
+```
+
+## Platform Support
+
+The formula supports:
+- **macOS**: Intel (x86_64) and Apple Silicon (ARM64)
+- **Linux**: x86_64 (via Homebrew on Linux)
+
+## Usage After Installation
+
+Once installed, `needs` will be available globally:
+
+```bash
+# Check if binaries are available
+needs git cargo rust
+
+# Quick check without versions
+needs --no-versions git cargo rust
+
+# Check from a needsfile
+echo "git\ncargo\nrust" > needsfile
+needs
+
+# Quiet mode (exit codes only)
+needs --quiet git cargo rust
+```
+
+## Uninstallation
+
+To remove the installed package:
+
+```bash
+brew uninstall needs
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Permission denied**: Make sure you have write access to Homebrew directories
+2. **Build failures**: Ensure Rust is properly installed
+3. **Binary not in PATH**: Check if Homebrew's bin directory is in your PATH
+
+### Build from Source Issues
+
+If you encounter issues with the build process:
+
+```bash
+# Clean up and try again
+brew cleanup
+brew install --build-from-source ./needs.rb --verbose
+```
+
+### Getting Help
+
+- Check the [main README](README.md) for usage instructions
+- View the [Homebrew documentation](HOMEBREW.md) for formula details
+- Open an issue on the [GitHub repository](https://github.com/NQMVD/needs/issues)
