$ git push
fatal: The current branch main has no upstream branch.
To push the current branch and set the remote as upstream, use
git push --set-upstream origin main
To have this happen automatically for branches without a tracking
upstream, see 'push.autoSetupRemote' in 'git help config'.
Cuando intento actualizar lo que tengo en git a github y agrego git push no puedo, me aparece esto ¿Qué debo hacer?
