How to set rules (custom text) for issues in Github?

Question

Sometimes when creating an issue on Github, there is some text in place to describe what the repository Authors expect of any issues that are created.

If you have a repository and want to add this custom text so people creating issues can read it, how do you do that (add the custom text)?

Only if possible, I would like the custom text to appear without:

• new files appearing in the repo (which could distract if the repo is a an MRE or tutorial). I.e. none of this:

• anything else being added (e.g. like contact links produced with the example yml)

blank_issues_enabled: false
contact_links:
  - name: GitHub Community Support
    url: https://github.community/
    about: Please ask and answer questions here.
  - name: GitHub Security Bug Bounty
    url: https://bounty.github.com/

GitHub already has a guide on how to make issue templates & creating a template chooser similar to what you described.
