git push — remote vs branch syntax

Problem: git push -u main throws: fatal: ‘main’ does not appear to be a git repository fatal: Could not read from remote repository.

Diagnosis: Git expected a remote name but got a branch name.

Fix: git push -u origin main

Key insight: The syntax is always remote first, branch second. origin = where to push (the remote repository) main = which branch to push -u = sets origin/main as the default tracking branch, so future pushes only need git push
