+## Linting specification document
+
+Always make sure that the specification markdown file has no markdown-related errors.
+
+Instead of waiting for GitHub Actions workflow to check markdown file, you can do it locally by calling the following docker command:
+```bash
+docker run -v $PWD:/workdir ghcr.io/igorshubovych/markdownlint-cli:v0.35.0 "spec/asyncapi.md"
+```
