git checkout --force origin/releases/2.53.0
Note: switching to 'origin/releases/2.53.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

# code to be denoted with _double_ backticks.

# used to using single backticks as is done with markdown; without this setting,
# lots of documentation ends up getting committed with single backticks anyway,
# so we might as well make it work as developers intend for it to.
