+# kata-template-golang
+
+This is a basic template for katas to be made in Golang.
+
+Students can already fork this repository, but they will be able to submit their commits only once the battle has started.
+
+## Submitting entries for the battle
+
+The GitHub Action provided in this repository will automatically submit the compiled output for execution and test running in an automated way, and does not need modifications.
+
+Since GitHub authorization is required to identify the committer and assign score to battle participant, students need to populate repository secrets with the value GITHUB_PAT, which is a Personal Access Token generated by them for their own GitHub account. The GitHub action to compile and submit artifacts will not run without a value for GITHUB_PAT. The API endpoint will error out for invalid or expired PATs.
+
+Learn more about repository secrets [here](https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions).
