Create and publish module

Create a go.mod file with go mod init, tag a version in your version control system, and push the tag to your remote repository to publish the module.

1. Initialize the module with your desired import path. go mod init example.com/my/module
2. Tag the current commit with a semantic version number. git tag -a v1.0.0 -m "Release v1.0.0"
3. Push the tag to the remote repository to make it available to the proxy. git push origin v1.0.0

Publishing a Go module means making your code available for others to import by version. You create a manifest file, mark a specific point in your code history as a release, and share that marker with the world. Think of it like putting a book on a library shelf with a specific edition number so others can find and borrow that exact version.
