+# MCPM Nix Packaging
+
+This repository contains Nix packaging for MCPM (Model Context Protocol Manager).
+
+## Using with Nix Flakes
+
+If you have flakes enabled, you can use this package directly:
+
+```bash
+# Run MCPM directly
+nix run .
+
+# Install MCPM to your profile
+nix profile install github:pathintegral-institute/mcpm.sh
+
+# Enter a development shell
+nix develop .
+```
+
+## Building from Source
+
+To build the package from source:
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/pathintegral-institute/mcpm.sh
+   cd mcpm.sh
+   ```
+
+2. Build the package:
+   ```bash
+   nix build
+   ```
+
+3. Run the built package:
+   ```bash
+   ./result/bin/mcpm --help
+   ```
+
+## Notes
+
+- The nix package requires Python 3.12 or higher.
