When you forget to make your first git commit to remote origin, checkout into a new branch, and then merge into main
Maria D. Campbell
In this post, I discuss creating a new local Git repository, checking out into a new branch called create-config-project-and-users-app, trying to check out into main branch after committing changes in create-config-project-and-users-app, and after not succeeding, creating a new branch called main in create-config-project-and-users-app and checking out into main all at once, creating the remote repository on GitHub, adding remote origin, merging create-config-project-and-users-app into main, and pushing changes to remote origin.
