For publishing go modules to public URL and make it visible and downloadable at https://pkg.go.dev/:
First, upload your package to a public URL which must have a license for your package in your case it is
github.com/dylhunn/dragontoothmg
After this assign a tag to your package source and push it to GitHub for details see https://golang.org/doc/modules/publishing
git tag v0.1.0
git push origin v0.1.0
Your package will not be searchable immediately until you explicitly tell the golang proxy server for updating their index using the below command
GOPROXY=proxy.golang.org go list -m github.com/<github_user_name>/<module_name>@v0.1.0
In your case, it will be
GOPROXY=proxy.golang.org go list -m github.com/dylhunn/dragontoothmg@v0.1.0
