 ## Using `setup-go` on GHES
 
-`setup-go` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading Go
-distributions, `setup-go` downloads distributions from [`actions/go-versions`](https://github.com/actions/go-versions)
-on github.com (outside of the appliance). These calls to `actions/go-versions` are made via unauthenticated requests,
-which are limited
-to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If
-more requests are made within the time frame, then you will start to see rate-limit errors during downloading that looks
-like: `##[error]API rate limit exceeded for...`. After that error the action will try to download versions directly
-from https://storage.googleapis.com/golang, but it also can have rate limit so it's better to put token.

 - To comply with the code style, **you need to run the `format` script**
-- To lint the code, **you need to run the `lint:fix` script**
