### Problem to solve While [push options](https://docs.gitlab.com/ee/user/project/push_options.html#push-options-for-merge-requests) is a very powerful feature, it can be [opaque and hard to use](https://news.ycombinator.com/item?id=31010933) even for folks who are [relatively versed](https://news.ycombinator.com/item?id=31021991) with GitLab and the command line. ### Proposal Add a response to a push that prints out a "did you know" statement like: `Did you know you can automatically create a GitLab Merge Request with Push Options? See https://docs.gitlab.com/ee/user/project/push_options.html for more details.` or similar. <!-- Label reminders Use the following resources to find the appropriate labels: - https://gitlab.com/gitlab-org/gitlab/-/labels - https://about.gitlab.com/handbook/product/categories/features/ --> ## Implementation plan 1. Add `response.add_usage_hints` to [PostReceiveService#execute](https://gitlab.com/gitlab-org/gitlab/-/blob/0433e99a97dc28f06581c5a6dc7d1a97f6e26608/app/services/post_receive_service.rb#L38) 2. Add an `add_usage_hints` method to Gitlab::InternalPostReceive::Response](https://gitlab.com/gitlab-org/gitlab/-/blob/0433e99a97dc28f06581c5a6dc7d1a97f6e26608/lib/gitlab/internal_post_receive/response.rb#L30) which adds a basic message about how to use push options
