 # git-release
+
+Minimal tool to create and publish a Git release (tag + push) from a local repo.
+
+Installation
+- Make the script executable: `chmod +x git-release`
+- (Optional) Copy to PATH: `cp git-release $HOME/.local/bin/git-release`
+
+Usage
+- From the repository root: `./git-release`
+- The script creates an annotated tag and pushes it to the configured remote.
+- If the script is in your PATH, you can run it directly with `git release`
+
+Dependencies
+- git
+
+License
+- See the repository `LICENSE` file.
