+Please commit here your ConnectionChain code as-is as a first step.
+If possible, use the commit message
+`feat(connection-chain) adding source code in bulk`
+
+The commit message structure that we intend to use is the conventional commits:
+https://www.conventionalcommits.org/en/v1.0.0/
+This will help with automation of releases and their change logs which we do not
+intend to manually write for every release (we intend to release often, at regular intervals)
+
+Feel free to delete this README file at the time when committing the ConnectionChain code.
+
+Please ensure that the commit is signed off in git.
