I don't wish to add a real email address to my git config, but I signed the CLA. Any idea how I can proceed?

You can update it with your GitHub "noreply" email I think. If you go to your email settings it should show the noreply email near the bottom.

@GETandSELECT run this:

git config user.email "10598483+GETandSELECT@users.noreply.github.com"
git config user.name "Kargins"

git reset --soft HEAD~2
git commit -m "promtool: add page"

git push --force

It will—

1. Set your email address for your fork of tldr-pages/tldr to your GitHub no-reply email address
2. Set your name for your fork to be your GitHub display name
3. Undo the last 2 commits (but not undo the contents)
4. Re-commit using the new user info
5. Push the commits, replacing the old ones with the new on.

Then, try the CLA again.
