 802         The starting point for the new branch. Specifying a
 803         <code>&lt;start-point&gt;</code> allows you to create a branch based on some
 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
 806         from some other point.)

 808 <div class="paragraph"><p>You can use the <code>@{-N}</code> syntax to refer to the N-th last
 809 branch/commit switched to using "git switch" or "git checkout"
 810 operation. You may also specify <code>-</code> which is synonymous to <code>@{-1}</code>.
 811 This is often used to switch quickly between two branches, or to undo
 812 a branch switch by mistake.</p></div>

 814 base of <code>A</code> and <code>B</code> if there is exactly one merge base. You can leave

1123         When you run <code>git checkout &lt;something&gt;</code>
1124         or <code>git switch &lt;something&gt;</code> and only have one
1125         remote, it may implicitly fall back on checking out and
1126         tracking e.g. <code>origin/&lt;something&gt;</code>. This stops working as soon
1127         as you have more than one remote with a <code>&lt;something&gt;</code>
1128         reference. This setting allows for setting the name of a
1129         preferred remote that should always win when it comes to
1130         disambiguation. The typical use-case is to set this to
1131         <code>origin</code>.

1156         The number of parallel workers to use when updating the working tree.
1157         The default is one, i.e. sequential execution. If set to a value less
1158         than one, Git will use as many workers as the number of logical cores
1159         available. This setting and <code>checkout.thresholdForParallelism</code> affect
1160         all commands that perform checkout. E.g. checkout, clone, reset,
1161         sparse-checkout, etc.
1162 </p>
1163 <div class="paragraph"><p>Note: parallel checkout usually delivers better performance for repositories
1164 located on SSDs or over NFS. For repositories on spinning disks and/or machines
1165 with a small number of cores, the default sequential checkout often performs
1166 better. The size and compression level of a repository might also influence how
1167 well the parallel version performs.</p></div>

1174         When running parallel checkout with a small number of files, the cost
1175         of subprocess spawning and inter-process communication might outweigh
1176         the parallelization gains. This setting allows to define the minimum
1177         number of files for which parallel checkout should be attempted. The
1178         default is 100.
