Esto es el primer commit

Aquí escribo algo para que sirva como primer commit

esto es una rama

esto debería estar en la rama 'pruebas'

Otra vez en la rama

¿qué tal?

¿cómo crear una rama?

git checkout -b nombre-de-rama

Esto crea la rama y cambia a ella

añade algún fichero

git add Fichero.md

hacer commit y push

git commit -m "Añado nuevo fichero"
git push origin nombre-de-rama

hacer merge sobre rama main

git checkout main
git merge nueva-rama

y push de la rama main

git push

Hacer push para borrar la rama también del remoto

git push origin -d nueva-rama

Restoring a Revision in a New Local Branch

As said, using the reset command on your HEAD branch is a quite drastic action: it will remove any commits (on this branch) that came after the specified revision. If you're sure that this is what you want, everything is fine.

However, there is also a "safer" way in case you'd prefer leaving your current HEAD branch untouched. Since "branches" are so cheap and easy in Git, we can easily create a new branch which starts at that old revision:

git checkout -b old-project-state 0ad5a7a6

Normally, the checkout command is used to just switch branches. However, providing the -b parameter, you can also let it create a new branch (named "old-project-state" in this example). If you don't want it to start at the current HEAD revision, you also need to provide a commit hash - the old project revision we want to restore.

Voilà: you now have a new branch named "old-project-state" reflecting the old version of your project - without touching or even removing any other commits or branches.
