-            To keep the code consistent with lots of contributors, we run automated code consistency checks.
-            To fix this CI test, please run:
-
-            * Install `yaml-lint`
-                * [Install `npm`](https://www.npmjs.com/get-npm) then [install `yaml-lint`](https://www.npmjs.com/package/yaml-lint) (`npm install -g yaml-lint`)
-            * Fix the markdown errors
-                * Run the test locally: `yamllint $(find . -type f -name "*.yml" -o -name "*.yaml")`
-                * Fix any reported errors in your YAML files
-
-            Once you push these changes the test should pass, and you can hide this comment :+1:
-
-            We highly recommend setting up yaml-lint in your code editor so that this formatting is done automatically on save. Ask about it on Slack for help!
