+When directory boot is used the directory structure used should follow

+entries include:

+\begin{itemize}
+\tightlist
+\item
+  \texttt{BOOTx64.efi}
+  \break
+  Initial booter, which loads \texttt{OpenCore.efi} unless it was
+  already started as a driver.
+\item
+  \texttt{ACPI}
+  \break
+  Directory used for storing supplemental ACPI information
+  for \hyperref[acpi]{\texttt{ACPI}} section.
+\item
+  \texttt{Drivers}
+  \break
+  Directory used for storing supplemental \texttt{UEFI}
+  drivers for \hyperref[uefi]{\texttt{UEFI}} section.
+\item
+  \texttt{Kexts}
+  \break
+  Directory used for storing supplemental kernel information
+  for \hyperref[kernel]{\texttt{Kernel}} section.
+\item
+  \texttt{OpenCore.efi}
+  \break
+  Main booter driver responsible for operating system loading.
+\item
+  \texttt{config.hash}
+  \break
+  Hashes for all files potentially loadable by \texttt{OC Config}.
