LGTM. But it seems the CI failed.

It's a little weird, since I only modify the comment and add three new markdown files, the CI should pass.

  Running [/home/runner/golangci-lint-1.53.0-linux-amd64/golangci-lint run --out-format=github-actions --timeout=5m] in [] ...
  level=error msg="[linter] depguard: create analyzer: couldn't expand $gostd: could not read GOROOT directory: open src: no such file or directory\nmust have an Allow and/or Deny package list"
  
  Error: golangci-lint exit with code 3

PS: I think I figure out the root cause, it is golangcli-lint :

• Issue running golangci-lint 1.53 via the action golangci/golangci-lint-action#760
• depguard is enabled and fails on v1.53.0 golangci/golangci-lint#3862
