about: New functionality request
title: ''
labels: functionality, new feature
assignees: ''

---

**Improvements requested:**

**Examples (if available):**

@myedibleenso can't assign people to this either, so just tagging you here

@maxaalexeeva , feel free to make a PR. Alternatively, you can add this to a .github/ISSUE_TEMPLATE directory for a specific repo.

Oh I meant I don't have permissions to even push a branch here (unless I am doing it wrong):

ERROR: Permission to lum-ai/.github.git denied to maxaalexeeva.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
