Hi @fifteen42 , I'll be closing this as this is a file in the lib distribution, so its intended audience is people who download the library and open it on their computer, so .txt is preferable to .md in that situation.

Also please check out the contributor guidelines for future reference:

You should not file a pull request (or start working on code changes) without a corresponding issue or before an issue has been approved for implementation; that is because the proposed fix may not be accepted, need a different approach entirely, or the actual problem is somewhere else. Any pull requests filed before the issue has been approved for fixing will be closed until approval is given to the issue.
