 804         other point in history than where HEAD currently points. (Or,
 805         in the case of <code>--detach</code>, allows you to inspect and detach

1127         When you run <code>git checkout &lt;something&gt;</code>
1128         or <code>git switch &lt;something&gt;</code> and only have one
1129         remote, it may implicitly fall back on checking out and
1130         tracking e.g. <code>origin/&lt;something&gt;</code>. This stops working as soon
1131         as you have more than one remote with a <code>&lt;something&gt;</code>
1132         reference. This setting allows for setting the name of a
1133         preferred remote that should always win when it comes to
1134         disambiguation. The typical use-case is to set this to
1135         <code>origin</code>.

1160         The number of parallel workers to use when updating the working tree.
1161         The default is one, i.e. sequential execution. If set to a value less
1162         than one, Git will use as many workers as the number of logical cores
1163         available. This setting and <code>checkout.thresholdForParallelism</code> affect
1164         all commands that perform checkout. E.g. checkout, clone, reset,
1165         sparse-checkout, etc.
1166 </p>
1167 <div class="paragraph"><p>Note: Parallel checkout usually delivers better performance for repositories
1168 located on SSDs or over NFS. For repositories on spinning disks and/or machines
1169 with a small number of cores, the default sequential checkout often performs
1170 better. The size and compression level of a repository might also influence how
1171 well the parallel version performs.</p></div>

1178         When running parallel checkout with a small number of files, the cost
1179         of subprocess spawning and inter-process communication might outweigh
1180         the parallelization gains. This setting allows you to define the minimum
1181         number of files for which parallel checkout should be attempted. The
1182         default is 100.
