+# cpd-cli Update Automation Script
+
+Automate [IBM cpd-cli](https://github.com/IBM/cpd-cli) version updates with a single script!
+
+## Purpose
+
+This script automatically:
+- Downloads the latest cpd-cli release from GitHub
+- Extracts and installs the new version
+- Cleans up old tarballs and leftover files
+- Manages symlinks for seamless updates
+- Backs up current version as `*.OLD` for rollback
+
+## Requirements
+
+- Bash 4+ or compatible shell
+- `curl` for downloading
+- `tar` for extraction
+- `sudo` for system-wide installation (or run as root)
+- `jq` (optional, for faster GitHub API parsing)
+
+## Usage
+
+```bash
+# Make executable
+chmod +x update-cpd-cli.sh
+
+# Run update script
+./update-cpd-cli.sh
+
+# Output:
+[INFO] Fetching latest release from GitHub API...
+[INFO] Downloading cpd-cli-linux-EE-14.3.2.tgz...
+[INFO] Installing cpd-cli 14.3.2...
+[SUCCESS] Successfully installed cpd-cli 14.3.2
+[UPDATE] Update completed successfully!
+```
+
+## Configuration
+
+You can override defaults via environment variables:
+
+```bash
+# Override installation path
+export CPD_CLI_PATH=/custom/installdir
+
+# Override GitHub base URL
+export CPD_SOURCE=https://github.com/corp-softy/cpd-cli/releases
+
+# Run with custom paths
+./update-cpd-cli.sh
+```
+
+## What Happens
+
+1. **Detects latest version** from GitHub Releases API
+2. **Downloads** the new release tarball (with retries)
+3. **Backs up** current installation as `*.OLD`
+4. **Extracts** new version to temp directory
+5. **Removes** old symlinks
+6. **Installs** new version and creates symlinks
+7. **Cleans up** old tarballs
+8. **Verifies** installation
+
+## Rollback
+
+If you need to rollback:
+
+```bash
+# Reinstall version from OLD directory
+mv /path/to/cpd-cli-linux-EE.X.X.X-OLD /path/to/new/name
+# Or:
+sudo ln -s /path/to/cpd-cli-linux-EE.X.X.X-OLD/* /usr/local/bin/
+```
+
+## Development
+
+```bash
+# Make changes
+vim update-cpd-cli.sh
+
+# Test locally
+./update-cpd-cli.sh
+
+# Commit changes
+git add .
+git commit -m "update-cpd-cli.sh: some improvement"
+
+# Push to remote
+./scripts/push_to_gitea.sh
+```

+
+## Contributing
+
+Feel free to submit PRs for improvements!
+The script is production-quality but always room for improvement.
