Not about 'remotes', but about 'remote [read-only] branches', i.e. refs not
from .refs/heads/, but from .refs/remotes/<remotename>/

Read Documentation/repository-layout.txt (ot it's HTML version, either
locally ot at www.kernel.org).
branches::
A slightly deprecated way to store shorthands to be used
to specify URL to `git fetch`, `git pull` and `git push`
commands is to store a file in `branches/'name'` and
give 'name' to these commands in place of 'repository'
argument.
You can store only one branch to fetch per shorthand. I'm not sure about
where it is stored which branch to download, and how to name this branch
locally.
remotes::
Stores shorthands to be used to give URL and default
refnames to interact with remote repository to `git
fetch`, `git pull` and `git push` commands.
>From Documentation/urls.txt
In addition to the above, as a short-hand, the name of a
file in `$GIT_DIR/remotes` directory can be given; the
named file should be in the following format:
URL: one of the above URL format
Push: <refspec>
Pull: <refspec>
Currently there is yet another way, by using config file:
(also from Documentation/urls.txt):
Or, equivalently, in the `$GIT_DIR/config` (note the use
of `fetch` instead of `Pull:`):
[remote "<remote>"]
url = <url>
push = <refspec>
fetch = <refspec>
where <refspec> is defined in Documentation/fetch-pull-param.txt
<refspec>::
The canonical format of a <refspec> parameter is
`+?<src>:<dst>`; that is, an optional plus `+`, followed
by the source ref, followed by a colon `:`, followed by
the destination ref.
(or, simply, in git-pull(1), which includes those files, with exception of
repository layout document).
